Stellite 12 Weartech WT-12 Stellite 12 Green Hard Facing Rod Green
Color Plastics Paper-Making Chemical Fiber
Product Description
Allotech WL-Co12 that produces a deposit for high heat and
corrosion resistance, with excellent wear properties. The
Machinability, WL-Co12 makes it a good choice for knife cutting
edges in the carpet, paper, and plastic industry. WL-Co12 deposits
provide resistance to all types of wear, including galling. It can
be applied to all weldable steels, including stainless steels.
Another similar type is Co 12H rod, which has higher hardness.
