GMM MIG 2209 (ER2209)

ER2209 is intended to weld duplex stainless steels. It exhibits high tensile strength and resistance to stress and corrosion cracking. Exhibits a low ferrite. Weld deposit has an austenite and ferrite microstructure which classifies 2209 as a “duplex stainless”. In media containing chloride and hydrogen sulphide the alloy has a high resistance to intergranular, pitting and especially to stress corrosion.
