WISDOM Brand Chinese Leading Manufacturer
Hardfacing welding series
We are your reliable alloy consultant
PRODUCT INTRODUCTION
WISDOM WD-Co12 that produces a deposit for high heat and corrosion resistance, with excellent wear properties. The Machineability, WD-Co12 makes it a good choice for knife cutting edges in the carpet, paper, and plastic industry. WD-Co12 deposits provide resistance to all types of wear, including galling. It can be applied to all weldable steels, including stainless steels.
