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. Stainless steel tee is the key pipe fitting used for the connection of pipeline branches, which is divided into two categories: equal diameter tee and different diameter tee according to the difference in the diameter of the pipe end. The product adopts hydraulic expansion, hot pressing forming or welding forming and other manufacturing processes, and the applicable materials cover stainless steel materials such as 304 and 316L, and conforms to more than ten international standards such as national standard (GB/T12459) and American standard (ASME B16.9). As the core component of the industrial pipeline system, the stainless steel tee undertakes the functions of diversion and confluence, pressure balance and direction conversion, and is widely used in petrochemical, natural gas transmission, power equipment, food and pharmaceutical industries, etc., and its corrosion resistance is enhanced by pickling and passivation processes
