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.
