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.
Components which serve as impact elements or opposing bodies,
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).
