Wear-Arc Ni-Manganese is a "build-up" alloy that produces a crack resistant weld deposit that forms a ductile, hig strength bond.
Wear-Arc Nickel Manganese weld deposit is crack resistant and forms a ductile, high-strength fusion bond on manganese steel. The austenitic structure of the weld provides excellent resistance to wear caused by heavy impact and compressive loads. Under conditions of continuous impact, the deposit surface work hardens to a BHN of 510. Wear-Arc Nickel Manganese is best suited for applications where severe impact and compressive forces are encountered continuously. Because of the sound, high-strength welds from this electrode, it should also be used for the attachment welding of wear plates, teeth, rounds, and shapes of manganese steel.

Wear-Arc Nickel Manganese electrodes require no special technique of application. When welding manganese steel, these general recommendations should be followed:
1. Weld only on sound, clean, unhardened base metal.
2. The use of preheat on manganese steel is not recommended. Avoid overheating the base metal by using the lowest current which produces good metal transfer and arc characteristics. Keep austenitic manganese steel below 600ºF (315ºC), interpass temperature.
Weld deposits can be cut with oxy-acetylene torch or by air carbon-arc cutting.
