HFK 135-G is CO2 gas-shielded and low alloyed flux cored wire. The deposit is tough, machinable, and proper for components subject to metal-to-metal wear. It also can be used for buildup.

Typical applications

Rebuilding and buffering of rolled mechanical components, carbon steel rolls, carrier rolls, tractor rollers, shafts, forging tools, and dies.
