GB/T 984 EDCrMn-B-16 GB/T 984 EDCrMn-B-15
Suitable for surfacing welding of parts damaged by cavitation in hydraulic turbines and high-manganese steel components requiring high wear resistance and toughness, such as hydraulic turbine blades, guide vanes, railway switches, screw conveyors, bulldozer blades, grab buckets, crusher blades, etc.
A high CrMn type surfacing welding electrode with a low-hydrogen coating. The weld metal can be work-hardened, is highly tough, cavitation-resistant, and has good crack resistance.
D276 AC, DC reverse polarity (AC, DC⁺); D277 DC reverse polarity (DC⁺)
