VAUTID VVP 150
For highly wear-resistant hardfacing layers
This composite wear plate comprises a base plate which has been overlaid, using a special metal arc welding process, with our highly abrasion-resistant VAUTID 150 hardfacing welding consumable.
In VAUTID 150, the abrasion wear resistance of a traditional chrome carbide alloy is significantly increased by the addition of boron.
- Components which are exposed to temperatures up to 350°C.
- To protect surfaces subject to a high level of abrasion combined with moderate shock loadings, e.g. compression screws and feeder screws, dust ducts, and separator and cyclone components.
This welding alloy is also available as a VAUTID hardfacing welding consumable (VAUTID 150).
In abrasive applications, VAUTID 150 extends service life up to a factor of 10 compared to S235JR
