Product Introduction
Properties and Applications
The raw material of MSM-NM50Ni-1 welding wire is martensitic stainless steel, featuring an excellent combination of strength and toughness. The surfacing layer formed by this welding wire has good machinability, along with high hardness, moderate toughness, high strength and outstanding corrosion resistance. This welding wire also exhibits excellent weldability and low susceptibility to welding cracks, making it suitable for surfacing the surfaces of components that require wear resistance, corrosion resistance, as well as high strength and toughness.

Precautions
1. Suitable for welding processes such as MIG, MAG, TIG or plasma arc welding. The shielding gas shall be 100% Ar or argon-rich mixed gas.
2. Oil stains, moisture, oxide films and other contaminants on the welding area must be thoroughly removed.
3. Effective wind shielding shall be provided at the welding site to prevent the dispersion of shielding gas which may cause welding defects.
4. The humidity of the welding environment should generally not exceed 70%.
5. The preheating or interpass temperature shall generally be controlled within the range of 100–300℃.
