What is HAYNES® 556® Welding Wire?
HAYNES® 556® Welding Wire is a distinctive iron-nickel-chromium-cobalt alloy, featuring a composition of about 22% chromium, 20% nickel, 18% cobalt, 3% molybdenum, along with small amounts of tungsten, silicon, and manganese. This unique blend provides remarkable strength, oxidation resistance, and carburization resistance at temperatures reaching 2100°F (1150°C). It also boasts excellent resistance to sulfidation and hot corrosion in both oxidizing and reducing environments. On the mechanical side, HAYNES® 556® showcases high tensile strength, good creep and stress-rupture resistance, and outstanding weldability, making it perfect for demanding industrial settings that require consistent high-temperature performance.
