Description: Ni327 -6 is a nickel-based electrode with low-hydrogen sodium coating. Use DCEP (direct current electrode positive). The deposited metal has excellent plasticity, toughness and crack resistance. Deposited metal has a linear expansion coefficient similar to that of steel, and has high strength and strong corrosion resistance at room temperature and high temperature. Application: It is used for the welding of Ni9% steel, and can also be used for welding of dissimilar steels and difficult-to-weld alloys.
