ABSTRACT
Duplex stainless steel 2205 is an alloy containing 22% Cr and 5% Ni. The steel microstructures are a δ-ferrite matrix with BCC structure with intercalated FCC lattice with γ-austenite in the ratio 50:50. Duplex stainless steel is used in industry for its high mechanical and corrosion resistance, better than in ferritic or austenitic stainless steels. During the welding process a low intensity electromagnetic interaction was induced using axial external electromagnetic fields 0, 3 and 12 mT. Resistance to crack formation and growth was also evaluated in a low cycle corrosion fatigue test mode to monitor short crack behavior. It was found that low intensity electromagnetic interaction (3 mT) improves localized corrosion resistance.
