CORODUR 721 is a powder wire with an alloyed Fe-B-Cr weld metal with a martensitic carbide structure. It is suitable for highly wear-resistant surfacings subject to minor impact and severe wear at temperatures up to 450°C. Due to the high hardness, the surfacing should not exceed a thickness of 4 mm.
