CORODUR 721 is a flux cored wire with alloyed Fe-B-Cr-weld metal with a martensitic carbide structure. It is suitable for highly abrasion resistant hardfacings that are exposed to minor impact and high wear at temperatures of up to 450°C. Due to its high hardness the hardfacing should not exceed 4 mm thickness.
