Cast stainless steel alloys are an important element in VAUTID system solutions for fittings, food technology and in the chemical industry.
Mechanical properties
VAUTID stainless steel castings are used in food processing and in flue gas desulfurization applications in the chemical industry. They are also used for valves and fittings and in the manufacture of machines, pumps and pressure vessels.

Thanks to its mechanical properties, its good machinability and good weldability, VAUTID’s cast steel is not just a good choice for wear solutions.
Mechanical properties
VAUTID carbon steel castings are used in machinery manufacture and steel production, as well as in applications for pressure vessels, turbines and boilers, and crusher hammers.

With its high elongation coefficient and its tendency for surface cold work hardening under stress, VAUTID austenitic manganese steel is an outstanding solution for components that are subject to impact. It has understandably become a firm fixture in the VAUTID product portfolio.
Mechanical properties
VAUTID castings made from austenitic manganese steel are used in crusher jaws and crusher cones

Heat-resistant cast alloys are an important building block in VAUTID system solutions in the recycling industry and in cement and steel works.
Mechanical properties
VAUTID heat resistant cast iron is used for industrial furnace engineering (up to 1.150 °C), for stirring teeth (up to 1.100 °C) and for petroleum and natural gas plants (up to 1.100 °C).

This technology combines different casting materials within a single product. The various melts are poured one after another into different sections of the mold. They then solidify together. A firm bond forms between the different casting zones. This method meets in full the requirement to have different materials in different sections of the same casting, and avoids the need for compromise.

For example, this technique is used to produce hammers for crushing plants, in which the heads are made from a highly wear-resistant VAUTID alloy, while a free-machining cast steel is used in the area of the shank and the eye.

This manufacturing process can also be used to modify weldable areas of white cast iron components, so they can be assembled quickly and easily.

Thanks to the high level of automation and modern production techniques used in their manufacture, VAUTID composite castings offer an economical high-end solution for serial production parts that have to meet complex challenges.

For thin-walled components (30 mm max) that are subject to a combination of impact and abrasion
This alloy is used in the manufacture of highly abrasion-resistant castings that are also subject to moderate impact. Its wear resistance can be reduced through heat treatment. This is an advantage for close-tolerance parts in particular, as the part can then be precision machined. The process can be reversed. Once machining has been completed, the component’s wear resistance can be restored to its previous level.

VAUTID W7 is particularly suitable for thin-walled components, with wall thicknesses of up to 30 mm. In the VAUTID W72 and VAUTID W73 variants, the composition is modified to permit higher wall thicknesses.

Components that are subjected to very severe abrasion and significant impact g. hammers, impact heads, chisels, and beater bars.

For thin-walled components (30mm maximum) subject to low impact and high abrasion
VAUTID W3 is first in the range of highly wear-resistant casting materials developed by VAUTID engineers. This alloy has been specifically designed for thin-walled components which are subject to severe abrasion.

VAUTID W3 is a “naturally hard” material, i.e. it is already hard in its as-cast condition, and no heat treatment is needed to activate its wear-resistant properties. Which means that components cast in genuine VAUTID W3 offer a clear cost advantage.

Because of this material’s high wear-resistance, components made from VAUTID W3 cannot be machined.

Recommended applications:

Cast components that are exposed to temperatures up to 400°C.
Thin-walled components (< 30 mm) that are subject to severe abrasion, e.g. tiles used as liners in mixing plants or agitators.

For thin-walled components (30 mm max) that are subject to a combination of impact and abrasion
Due to their extreme hardness, components cast in VAUTID W4 offer outstanding resistance to abrasive wear. This specification has been adapted to give exceptional ductility, enabling it to handle moderate impact and shock loadings.

VAUTID W4 is a “naturally hard” material, i.e. its wear resistant properties are present as soon as the casting forms. Since no expensive heat treatment is required, products made in genuine VAUTID W4 offer a particularly economical solution.

Because of the material’s high wear-resistance, components made from VAUTID W4 cannot be machined.

Recommended applications:

Cast components that are exposed to temperatures up to 400°C.
Thin-walled components (< 30 mm) that are subject to abrasion and impact, e.g. liners in crushing plants, or deflector plates.

Best abrasion protection for horizontal and vertical welds (positions PC and PF)
With VAUTID high wear-resistance hardfacing welding consumables, the emphasis is on maximizing service life. Other properties, such as metal flow characteristics and the welding positions that these permit, are secondary to this overall objective.

However, if you need a wear-resistant welding consumable for special positions, then VAUTID 105 is the ideal choice. All VAUTID welding consumables are basically well suited to welding in positions PA and PB — but this alloy can also be used when welding in positions PC and PF.

Recommended applications:

For producing abrasion-resistant layers in welding positions PC and PF.

Best protection against combined impact and abrasion for horizontal and vertical welds (positions PC and PF)
This welding consumable produces a hardfaced layer that is both shock-resistant and impact-resistant. The metal flow characteristics have been designed for good weldability in positions PC and PF. This enables wear-resistant hardfaced layers to be produced on vertical surfaces. And that means plant improvement works can be carried out without the need for dismantling.

Recommended applications:

Producing layers which are both abrasion-resistant and impact-resistant in welding positions PC and PF.

For hardfacing layers with an extremely high level of wear resistance and good heat resistance properties
Carbides of tungsten, niobium and vanadium are some of the hardest and most effective particles available for wear protection. They are all combined in our tried-and-tested VAUTID 145. This alloy offers reliable protection against both extreme abrasion and high temperatures.

Recommended applications:

Components which are exposed to temperatures of up to 750°C.
Components which are subjected to very high levels of abrasive wear
e.g. sinter crushers, glass recycling equipment, and the wear edges of excavator buckets and chain conveyors.
Components which are subjected to very high levels of abrasion at elevated temperatures, such as hot gas ventilation fans, hot dust ducts and blast furnace bell liners.
This welding alloy is also available as a VAUTID composite wear plate, produced using a special metal arc welding process (VAUTID VVP 145).

For hardfacing layers with an exceptionally high level of wear resistance and very good heat resistance properties
VAUTID 147 represents an improvement on our tried-and-tested VAUTID 145 specification.
The result is even greater protection against abrasive wear and an increase in maximum operating temperature. But, as always, we only use cost-effective wear absorption elements, enabling us to achieve the best possible price-performance ratio.

For highly wear-resistant hardfacing in applications which also involve a low level of shock loading
Adding boron significantly increases the wear resistance of our classic VAUTID chrome carbide alloys. This is why VAUTID 150 produces a weld material with a particularly high hardness level. The boride and chrome carbide inclusions offer excellent resistance to abrasion.

Recommended applications:

Components which are exposed to temperatures up to 350°C.
Components which are subjected to significant abrasion combined with a low level of shock loading, e.g. compression screws and feeder screws, dust ducts, and separator and cyclone components.
This welding alloy is also available as a VAUTID composite wear plate, produced using a special metal arc welding process (VAUTID VVP 150).

For highly wear-resistant hardfacing, even with a low level of impact
VAUTID 100Mo is a variant of our well-proven VAUTID 100 specification. In addition to carbides of chrome, this welding material incorporates finely distributed special carbides, which increase resistance against abrasion wear. In addition, because of a specific adjustment to the formulation, VAUTID 100Mo has a finer gain structure than VAUTID 100. As a result, this weld material responds more flexibly to shock loads. This improves wear resistance under light impact conditions.

VAUTID 100Mo is therefore best suited for overlays on components which are subjected to high levels of abrasion and moderate impact loads.

Recommended applications:

Components which are exposed to temperatures up to 350°C.
Components which carry a steady flow of abrasive media and are also subject to light impact, e.g. chutes and material slides onto which bulk material of a medium particle size falls and slides, and grinding tables in vertical mills where the material being milled contains even larger objects.
Moving components which operate in homogenous abrasive media and strike solid bodies at moderate speeds, e.g. rollers and wear liners operating in very homogenous materials where no foreign bodies are present in the mill stock, centrifugal separators for sand, excavator bucket teeth and bucket edge wear strips.

For highly wear-resistant hardfacing layers in applications with a combination of impact and abrasion
This material combines compact, needle-shaped chrome carbides with small, extremely hard niobium carbides. Because of their shape, niobium carbides serve to stabilize the wear-resistant weld overlay. They work like clamps, holding the structure together against impact-generated forces. At the same time, their extreme hardness increases abrasion wear resistance.

In VAUTID 143, chrome carbide and niobium carbide complement each other to produce a material which offers outstanding protection against both abrasion and impact.

Recommended applications:

Components which are exposed to temperatures up to 350°C.
Components which are exposed not only to severe abrasion but also to significant impact, e.g. funnels into which highly abrasive materials drop and slide.
Moving components which operate in highly abrasive media and strike solid bodies at high speed, e.g. roll liners in crusher mills and high-pressure finishing rollers.

e.g. hammers in crushing mills processing hard materials, and beater bars.
This welding alloy is also available as a VAUTID composite wear plate, produced using a special metal arc welding process (VAUTID VVP 143).

Palm oil industry
This material was designed to meet the specific wear conditions encountered in the palm oil industry.

Carbides of chrome are used to protect crushing mills against the effects of abrasive plant fibers. The carbides are dispersed extremely finely within the structure, giving this product the elasticity and plasticity to absorb the impacts and shocks that arise during operations.

Recommended applications:

Components which are exposed to temperatures up to 350°C.
Moving parts operating in abrasive media which encounter moderately hard objects, e.g. feeder screws in biomass applications.
Components which serve as impact elements or opposing bodies,
e.g. impactors and blades used in vegetation shredding equipment.

For applications combining impact and abrasion
In VAUTID 80, finely distributed wear-resistant particles of chrome carbide form a reliable defense against abrasion wear. At the same time, their fine structure provides an elastic framework, thereby ensuring an extended service life under impact conditions.

VAUTID 80 is therefore ideal for parts which are exposed to a combination of impact and abrasion.

Among its applications, these properties have made VAUTID 80 the centerpiece of our wear protection system for the sugar industry.

Recommended applications:

Components which are exposed to temperatures up to 350°C.

e.g. impactors and blades used in vegetation shredding equipment, impact mill housings, and components in recycling facilities.

The all-round solution for hardfacing layers with excellent wear resistance
VAUTID 100 is recognized around the world as the industry standard for wear protection. This well-proven specification forms the basis of the entire VAUTID 100 product family. The concept behind this overlay material is as follows: the right proportion of extremely wear-resistant hard particles embedded within a stable matrix.

This formulation offers an excellent price-to-performance ratio and covers a wide range of applications. In its basic form, VAUTID 100 is a great all-rounder. Its tried-and-tested characteristics have been modified for specific applications, leading to several variants: VAUTID 100 T, VAUTID 100 Mo and VAUTID 100 C.

Recommended applications:

Components which are exposed to temperatures up to 350°C.
Components which carry a steady flow of abrasive media e.g. material slides, dust ducts, separators, liners in mixing plants, and side wall surfaces and grinding tables in vertical mills.
Components that operate in homogenous, abrasive media e.g. excavator buckets, mixer buckets, feeder screws, wear liners, and separator bars in vertical mills.
This welding alloy is also available as a VAUTID composite wear plate, produced using a special metal arc welding process (VAUTID VVP 100).

For tough, hard, heat-resistant overlays in applications where there is a combination of impact and abrasion
The metal used in VAUTID 70 contains titanium, which forms one of the hardest types of carbide in existence. Because of its titanium carbide content, this alloy offers excellent resistance to abrasive wear. The carbides of titanium are embedded in an extremely tough matrix. This provides particularly effective protection against impact. Furthermore, weld layers constructed from VAUTID 70 are crack-free and resistant to high temperatures.

Hence VAUTID 70 offers ideal wear protection for components which operate at elevated temperatures and are simultaneously subject to high levels of abrasion and impact.

Recommended applications:

Components exposed to temperatures up to 670°C.
Components which are subject to significant impact from abrasive materials,
e.g. deflector plates, blast furnace throat armor, funnels and chutes.
Moving components which operate in highly abrasive media and either strike solid bodies at high speed or experience extreme pressures within the media, e.g. high-pressure rollers, parts of crusher rolls, roller presses and hammers in hammer mills.
Metal-on-metal wear applications, e.g. tools for hot forming or forging steel components.

For impact loads and moderate abrasion
In impact load situations, it is important that the armored overlay is malleable and capable of being formed. This allows the kinetic energy of striking particles to be absorbed and, ideally, to be released again. VAUTID 40 meets this challenge in full. With its ductile matrix, this alloy offers exceptional protection against shock loadings, yet still contains a sufficient quantity of hard particles to provide moderate protection against abrasion as well.

It can even be machined after tempering, making this alloy particularly well-suited for the production of close-tolerance components. Very good results can also be achieved in metal-on-metal wear applications.

Recommended applications:

Components which are subject to both impact and abrasion, in applications where impact stresses are the major consideration, e.g. hammers for crushing plants handling moderately abrasive media.
Components which need to be machined after hard-facing.
Metal-on-metal wear applications, e.g. guides and rails.

For applications involving severe impact wear and for buffer layers
Shock loadings have a surface work-hardening effect on alloys with a high manganese content. With its very high manganese content, VAUTID 60 demonstrates exceptional resistance to impact wear.

This alloy produces an extremely tough, crack-resistant weld metal which is non-magnetic and has a high tensile strength. The material is characterized by excellent compatibility with all weldable steels, and it can be flame cut. Hence VAUTID 60 is suitable for tough, pressure-tight buffer layers and for hardfacing components which are predominantly subject to impact stresses. It is also suitable for the remanufacture of components made from high manganese steel, e.g. hammers, beater bars and crushing rolls.

Recommended applications:

Wear protection of components which are subject predominantly to impact stresses, e.g. impact heads, transfer points below fall pipes, and racks in blasting facilities.
As a buffer layer between components made of weldable steel and wear-resistant VAUTID welding consumables.

For tough hardfacing layers in high shock load applications
Alloys with a high manganese content work harden under impact. Hence they are very well-suited to protect components which are subject to impact forces; because the more an area is impacted, the harder it becomes.

With VAUTID 50, any weldable component can acquire this useful attribute. This material is also equally suitable for remanufacturing components made from high manganese steel.

Recommended applications:

As a buffer layer between steel components and wear-resistant VAUTID welding consumables.
Components which are subject predominantly to impact stresses, e.g. impact heads, transfer points below fall pipes, and racks in blasting facilities.

For pressure-tight, crack-resistant overlays and buffer layers
With its high compressive strength, this alloy is best suited for build-up layers and weld repairs to steel materials. This low-alloy welding consumable is crack-free, machinable and ductile.

Recommended applications:

As a buffer layer between steel components and wear-resistant VAUTID welding consumables.
When protecting or remanufacturing highly stressed machine components, such as crane pulleys, cable drums and rails.

For buffer layers and hardfacing
Due to its high compressive strength, VAUTID 30/9 is the ideal product for build-up layers in weld repairs. As a buffer layer material, this alloy works not only with all weldable steels and weldable steel castings, but also — and equally well — with steels that are difficult to weld, such as Cr-Ni-Mo grades.

It is also extremely well suited as a buffer layer when joining VAUTID composite wear plates. This crack-resistant, rustproof welding metal has work-hardening properties and offers a high level of resistance to pressure, impact and cavitation.

Recommended applications:

As a buffer layer for components made from steels that are difficult to weld, such as Cr-Ni-Mo grades, and wear-resistant VAUTID welding consumables.
In the remanufacture of components which are made from steels that are difficult to weld or are specifically required to be rustproof.
To protect components that are subject to pressure, impact or cavitation.
To protect weld joints in fabrications made from VAUTID composite wear plates

For overlays and buffer layers subject to impact and pressure
This is a traditional material for weld joints and buffer layer applications. It ensures that VAUTID wear protection alloys fuse securely with austenitic manganese steel and hardening steels.

Due to its excellent corrosion resistance qualities, work-hardening capabilities and high ductility, VAUTID 18/8/6 is especially well-suited for the protection and remanufacture of components which are subject to impact and pressure loads.

Recommended applications:

Buffer layers between components made from austenitic manganese steel or hardening steels and wear-resistant VAUTID welding consumables.
For use when remanufacturing components which are made from austenitic manganese steel or which have a specific ductility or corrosion-resistance requirement, e.g. rails, railway points/shunting switches, firing bolts and gears.
Components subject to high temperatures used in mineral wool production.
