Hardfacing alloy made for GMAW carbide embedding
- April 29, 2016
- Product Release
- Consumables
Postle Industries has introduced Postalloy® PS98 hardfacing alloy to be used as a matrix welding wire for tungsten carbide embedding, also known as GMAW carbide embedding. Tungsten carbide particles are fed from an overhead hopper directly into the alloy’s molten weld pool via vibratory feeding equipment. The resulting weld deposit, which has a hardness of 55 to 60 HRC, contains a large volume of tungsten carbide particles embedded in a hardface matrix alloy.
The alloy’s high-hardness tool steel microstructure is designed to encapsulate and protect the tungsten carbide particles from premature erosion. Comprising chromium and molybdenum, the triple-deoxidized, iron-based hardfacing matrix alloy provides an even distribution of carbide particles throughout the entire weld deposit.
