The Super duplex stainless steel UNS S32750 pipe fittings is combining the most desirable features of both austenitic and ferritic steel. It is high resistance to corrosion in a greater range of media. It's resistant to pitting and crevice corrosion and also chloride-containing environments because of molybdenum, high chromium and nitrogen level. However duplex microstructure provides this grade greater strength UNS S32750 low coefficient of thermal expansion and high heat conductivity 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 pipe fittings stainless steel UNS S32750 is ASME SA815 and ASTM A815. The thickness is 0.5 to 45mm. Its outer diameter is 6.0 to 630mm. The dimensions of the fitting are WT (0.5-45) mm and OD (6.0-630) mm. The schedule is SCH 20, 80, 30, 40 and STD. In length, the fitting available are single random and in cut length. To buy it online you must have to specify all about which specification tubing is needed for you. Accordingly, you will be served by sellers.
