Stainless steel 310S is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditionsthrough 2000°F. Grade 310S is a lower carbon version, less prone to embrittlement and sensitisation in service. The highchromium and medium nickel content make these steels capable for applications in reducing sulphur atmospheres containing H2S. They are widely used in moderately carburising atmospheres, as encountered in petrochemical environments. For more severe carburising atmospheres other heat resisting alloys should be selected. Grade 310 is not recommended for frequent liquid quenching as it suffers from thermal shock. The grade is often used in cryogenic applications, due to its toughness and low magnetic permeability. Socket welding tee is a highpressure pipeline connection fitting, mainly made of round steel or steel ingot forging blanks, and then processed by lathe.Forged Socket Weld Fittings Tee are used only in conjunction with ASME Pipe. Forged Pipe Fittings and Forged Socket Weld Fittings Tee Covers the Pressure, Tolerances, Dimensions, Temperature Ratings, Marking and Material Requirements for Forged Socket Weld Fittings Used in High-pressure Applications.
