ERNiCrMo-3 Nickel-Chromium-Moly Alloy Welding Wire
ERNiCrMo-3 Nickel-Chromium-Moly Alloy Welding Wire Introduction
ERNiCrMo-3 (NA625) is used primarily for gas tungsten and gas metal arc and matching composition base metals. It is also used for Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW) of Inconel 601, Inconel 625, Incoloy 825 and a range of high alloy austenitic and super austenitic stainless steels.
It can be used to weld dissimilar metal combinations such as steel, stainless steel, Inconel and Incoloy alloys. This Nickel-Chromium-Moly Alloy Wire provides excellent resistance to corrosion and oxidation, high strength and good fatigue resistance over a broad range of temperatures from cryogenic up to 1,800°F.
