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. The end cap on a pipe cap pressure vessel is a main pressure-bearing component of the pressure vessel. Its function is to seal.Firstly, it serves as the top and bottom of a cylindrical pressure vessel. Secondly, if the pipeline ends and is not intended to extend further, then a pipe cap is used to seal the pipe through welding. Products similar to the function of a pipe cap include blind flanges and pipe caps, but those two products can be disassembled. In contrast, once a pipe cap is welded, it cannot be disassembled. Associated fittings include pressure vessels, pipelines, flanges, elbows, tees, and crosses.
