Characteristics:
ERNiCrMo-3 or Inconel 625 is a nickel-chromium-molybdenum alloy solid bare wire. It is designed for welding Inconel 600 series , Nickle alloy to steel, to other nickel-base alloys. ERNiCrMo-3 provides moderate strengths, good fabricability, and superior corrosion resistance up to 1800°F temperatures and good oxidation resistance.
Applications:
It is suitable for welding of piping systems, reactor components in the power generation industry, furnace equipment, petrochemical plants and in marine and offshore environments.
Classification:
AWS A5.14 ERNiCrMo-3
