Duplex stainless steel has good welding performance and high strength. Compared with austenitic stainless steel, it is about double yield strength of stainless steel 316, 317 etc., it make the equipment lighter and stronger. Duplex stainless steel pipe has very good resistance to localized corrosion and stress corrosion cracking. Duplex steel is not intended to be used at temperatures above 300°C due to embrittlement, the continuous use temperature is from -50 to 250 °C.
