ER625 is a nickel-chromium-molybdenum filler metal used for MIG, TIG, submerged arc and plasma arc welding of Inconel® alloys 601, 625 and 690 as well as Incoloy® alloys 800, 825 and 800HT to themselves or to each other. Washington Alloy 625 is excellent for joining these Inconel® and Incoloy® alloys to dissimilar metals such as carbon steel, low alloy steel, ferritic and austenitic stainless steels. This filler metal produces weld deposits with excel lent corrosion and oxidation resistance against phosphoric acids, organic acids and seawater. Good resistance against pitting and stress corrosion cracking in chloride containing environments. The weld deposits exhibit high strength and fatigue resistance over a broad range of temperatures ranging from cryogenic up to 1800°F. ER625 is most commonly used in the chemical processing industry, pollution control equipment, marine equipment, nuclear reactor components, pump shafts.
