AMS 5837
AMS 5837 is the SAE Aerospace Material Specification for Inconel 625 (UNS N06625) nickel-chromium-molybdenum-niobium alloy welding wire. It is used as filler metal for gas tungsten arc (TIG) and gas metal arc (MIG) welding of Inconel 625 base metal, other nickel alloys, and dissimilar metal joints where high-strength, corrosion-resistant welds are required.
AMS 5837 wire produces welds with room-temperature tensile strength above 100 ksi and outstanding resistance to pitting, crevice corrosion, and chloride stress-corrosion cracking — maintaining weld integrity from cryogenic temperatures to 1800°F (982°C).
AMS 5837 wire is available in diameters from 0.030″ to 0.125″ (0.76–3.18 mm). Chemistry: Ni 58% min, Cr 20–23%, Mo 8–10%, Nb+Ta 3.15–4.15%, Fe 5% max. No post-weld heat treatment required for most applications. Weld metal microstructure is austenitic and not susceptible to precipitation during service.
