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.
- 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).
In abrasive applications, VAUTID 145 extends service life up to a factor of 14 compared to S235JR
