چکیده
Abstract Duplex stainless steels offer a high strength alternative to steel, while providing excellent corrosion resistance, due their dual-phase microstructure. This microstructure can be significantly influenced during welding, thus the maximum recommended heat input is usually 2.5 kJ/mm. In this research, we inspected (3 kJ/mm) weldability of NSSC 2120 lean duplex which designed and developed specifically for purpose. The welds were evaluated by metallographic techniques tests. It was found grade welded with without deterioration in phase balance
