Duplex stainless steels, are dual phase materials that combines excellent mechanical strength with good corrosion resistance. Nitrogen is a key element to form the dual phase balance of ferrite and austenite together with a structural stability that ensures good weldability. Understanding the correlation of the metallurgy to base material, filler metal, shielding gas and cooling rate makes you and expert in duplex stainless steel welding.
