Description

POSTALLOY®PS-11W with Reactive Core Technology™ (RCT) is a nickel base hardfacing cored wire containing a special blend of tungsten carbides for extreme abrasion as well as corrosion. The matrix is resistant to acids, bases, lye and other corrosive media. This alloy can be applied crack-free with the proper welding procedures. The alloying elements in the wire produce a higher hardness weld deposit that encapsulates and protects the carbide particles, reducing the premature wear caused by erosion to the carbide particles. As a result it achieves a considerable service life improvement in extreme applications compared to PS-10 which it has replaced. The alloy has a low melting range and features good weldability with a smooth arc, reduces weld dilution and carbide dilution to produce a truly outstanding multi-wear wire. Use on low carbon mild and low alloy steels, stainless, nickel and cast iron.
