The Super duplex stainless steel UNS S32750 pipe fittings is combining most desirable feature of both austenitic and ferritic steel. It is high resistance to corrosion to greater range of media. It’s being resistance to pitting and crevice corrosion into sweater and also chloride containing environment because of molybdenum, high chromium and nitrogen level. However duplex microstructure is providing this grade greater strength UNS S32750 low coefficient of thermal expansion and high conductivity of heat than austenitic steel. It is designed to meet the features like high strength, pitting resistance, crevice corrosion, erosion cracking, corrosion fatigue, stress corrosion cracking and strong weldability.
The specification of the super duplex stainless steel UNS S32750 pipe fittings is ASME SA815 and ASTM A815. The thickness is 0.5 to 45mm. Its outer diameter is 6.0 to 630mm. The dimensions of fitting are WT (0.5-45) mm and OD (6.0-630) mm. The schedule i
