摘要	Pitting corrosion resistance and mechanical properties of 2304 duplex stainless steel with different Cr-eq/Ni-eq values after plasma-arc welding and welding thermal simulation were systematically studied. The results showed that the lower the Cr-eq/Ni-eq value in the experimental range, the better the microstructure after welding or welding thermal cycle. High pitting resistance equivalent number in the chemical composition brought in low weight loss rate and high critical pitting temperature for base metal. Furthermore, as the Cr-eq/Ni-eq, value decreased, the degradation of pitting corrosion resistance after welding thermal cycle reduced. (C) 2013 Elsevier Ltd. All rights reserved.
