Product Description

Polystel Co 12 Erccocr-B Cobalt Based Alloy Stellite 12 Green High Temperature And High-Pressure Valve

Product Description

WLCo 12 cobalt based rod that produces a deposit for high heat and corrosion resistance, with excellent wear properties. The Machineability, WLCo 12 makes it a good choice for knife cutting edges in the carpet, paper, and plastic industry. WLCo 12 deposits provide resistance to all types of wear, including galling. It can be applied to all weldable steels, including stainless steels.
