Deep cryogenic treatment of metal materials
Thread Content
Austenitic stainless steel plates and tubes can be used directly in air separation cryogenic tanks (at temperatures of -196 degrees). Do valves made from cast or forged austenitic stainless steel require cryogenic treatment when used in environments below -20 degrees?
Austenitic stainless steels generally require cryogenic treatment only when used at temperatures below -101°C
Deep cryogenic treatment of austenitic stainless steel at low temperatures can improve the dimensional stability of the material
