The austenitic hard-manganese steel electrode Fidur 7/200 is suited for wear-resistant surfacings on materials and machine parts from hard-manganese steel, for example digging teeth, blow bars, crushing jaws, rail frogs and crossing pieces which are mainly impact and shock-loaded. The weld metal has in welding condition a hardness of 200 HB which can be increased up to 500 HB by work-hardening under mechanical strain.
