D256 High manganese steel surfacing electrode Model:EDMn-A-16
Description: High-manganese steel surfacing welding electrode, (at no-load voltage when AC welding is not less than 70V), when surfacing welding should use small current, narrow-track welding, hammering or water immediately when the red hot, in order to reduce the tendency of cracks. The surfacing metal is austenitic, high-manganese steel, which is characterized by work hardening, high toughness, and wear resistance.
Uses: Used for surfacing of various wear parts such as crushers, high manganese steel rails, buckets, bulldozers, etc.
