POSTALLOY®
PS-10
Description

POSTALLOY®PS-10 is a tungsten carbide, nickel base hardfacing wire designed to resist severe abrasion but unlike traditional tungsten carbide wires, it absorb more impact without fracturing. This alloy can be applied crack-free with the proper welding procedures. This alloy are great for parts that are repeatedly hardfaced and are prone to spalling. Because of the unique chemistry, Tungsten-Carbide-Nickel-Chromium-Silicon-Boron, PS-10 also has excellent resistance to erosive wear, frictional wear, corrosive wear, and maintain their hardness, even at temperatures of 1100°F (593°C). Weld deposits contain over 50% fully fused, pre-alloyed carbides. The alloying elements in this wire produces a high hardness alloy that encapsulates and protects the carbide particles, reducing premature wear caused by erosion next to the carbide particles. POSTALLOY®PS-10 has very good weldability and a very soft arc, this, in combination with the nickel matrix, reduces weld dilution and carbide dilution to produce a truly outstanding multi-wear wire.
