Austenitic stainless steel as a key cryogenic
Manual Gas Valves sealing materials at room temperature in a metastable state, the steel Manual Gas Valves is rapidly cooled from the austenite state, at lower temperatures (below Ms point) martensitic transformation occurs. At this time, the iron atoms and carbon atoms are not diffused, its transformation process is only the Fe lattice reorganization, no macroscopic manifestation of this diffusion phase change that is the size of the change in the Manual Gas Valves parts. Maximum deformation occurs austenitic stainless steel cryogenic treatment size changes, after a sample larger than the deep cold, cryogenic size after the second largest amount of deformation significantly reduced. To ensure Gas Top Burner Valve full martensitic transformation, the material should be finished before the material twice cryogenic treatment, change in use to minimize the Manual Gas Valves size at low temperatures. Austenitic stainless steel cryogenic treatment, it will effectively solve the material under cryogenic conditions of deformation problems in order to ensure that low-temperature Manual Gas Valves sealing performance.
