ER410NiMo
AWS A5.9: ER410NiMo is a solid wire rod for GTAW, suitable for welding 13/4 chromium-nickel steels, high strength martensitic steels. Weld metal has good resistance to corrosion, hydrocavitation and sulphide induced stress corrosion cracking. Main application is overlay mild and low alloy steels. Also used in Turbines, Valve bodies, High pressure piping, Offshore, Power generation. Grade 410NiMo steels are self-hardening steels and usually require pre-heating and stress relieving treatments in order to obtain adequate ductility.
Used to overlay mild and low alloy steels
Preheat and inter-pass temperatures of 300°F (150°C) or greater is recommended during welding
Post-weld heat treatment should not exceed 1150°F (620°C) as higher temperatures may result in hardening
