PS-98 Matrix

Postalloy® PS-98 Matrix hardfacing wire, alloyed with chromium and molybdenum is developed primarily to be used in conjunction with the MIG Carbide Embedding process. PS-98 Matrix provides a clean, molten and fluid weld bead that readily accepts tungsten carbide grit.

Improves the performance of MIG Tungsten Carbide embedded parts
• Hardness of 55-59Rc protects the tungsten carbide grit which has a hardness in excess of 75Rc.
• The molten weld results in an even distribution of carbide particles throughout the entire weld deposit.

Unlike soft metal steel welding wires which are commonly used with the MIG Carbide Embedding Process, the high hardness tool steel micro-structure of Postalloy® PS-98 Matrix is designed to encapsulate and protect the carbide particles from premature erosion. Use on carbon, low alloy steel and manganese steel.
