Field of application
Austenitic flux-cored wire for surfacing on parts made of austenitic manganese steel which are subjected mainly to impact and shock wear stress. Hammers, crusher rolls and cones, blow bars, etc . Welding must be carried out as cold as possible, since austenitic manganese steel tends towards grain growth and therefore towards embrittlement at temperatures above 400 ° C. The weld metal is brought to a hardness of 400-450 HB by work hardening
