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.
- Components which are exposed to temperatures of up to 850°C.
- Components which are subjected to very high levels of abrasive wear e.g. sinter crushers, glass recycling equipment, and material slides handling extremely abrasive media.
- Components which are subjected to very high levels of abrasion at elevated temperatures, such as hot gas ventilation fans, hot dust ducts, blast furnace bell liners and screens in smelting plants.
This welding alloy is also available as a VAUTID composite wear plate, produced using a special metal arc welding process (VAUTID VVP 147).
In abrasive applications, VAUTID 147 extends service life up to a factor of 16 compared to S235JR
