CLASSIFICATION: ERNiCrMo-3 per AWS A5.14

SelectAlloy 625-C is a nickel, chromium, molybdenum electrode primarily utilized for welding alloys 625, 601, 802 and 9% nickel using the gas metal arc and gas tungsten arc method of welding. This wire is also designed for welding NiCrMo to itself, to steel, to other nickel-based alloys and for cladding steel with NiCrMo weld metal and the clad side of joints in steel with NiCrMo alloy.

APPLICATIONS: SelectAlloy 625-C is an excellent choice for welding piping systems and reactor components in the power generation industry and for high temperature service in a variety of other engineering applications.
