Cryogenic treatment – Cryogenic Treatment of austenitic stainless steel for cryogenic valves

Most of Cr Ni austenitic stainless steels are in metastable state at room temperature, but martensitic transformation occurs in ultra-low temperature range due to lattice distortion. The temperature at which martensite begins to transform is the martensite transformation point (also known as transformation point), which is represented by the symbol Ms. The temperature of MS… Read more Cryogenic treatment – Cryogenic Treatment of austenitic stainless steel for cryogenic valves

Manufacturing method of ultra low temperature and cryogenic treatment equipment

At present, the mainstream technology of modification and strengthening treatment of formed metal materials, tools, moulds and accessories is coating. The disadvantages of coating technology are surface modification, high cost, long delivery cycle, complex technology and large investment, and it is powerless for non-standard parts, special-shaped parts and large workpieces. Cryogenic processing technology is a… Read more Manufacturing method of ultra low temperature and cryogenic treatment equipment
