D256 high manganese steel welding electrodes Model: EDMn-A-16 Description: high manganese steel welding electrodes, AC and DC (AC welding load voltage space of not less than 70V), surfacing should be used when a small current, narrow channel welding, Now while hammering the red hot or water, to reduce the tendency to crack. Surfacing metal is austenitic high manganese steel, with hardening, high toughness and wear resistance characteristics. Uses: for easy wear parts surfacing crusher, high manganese rails, bucket, bulldozer. Deposited metal chemical composition /% C≤1.1 Si≤1.3 Mn 11 -16 Other ≤5 Surfacing hardness HRC: HB≥170 22,
