(S225) Temperature dependence of grain refinement strengthening in SUS316L stainless steel

摘要

Austenitic stainless steels, represented by SUS316L (Fe-18Cr-12Ni-2Mo), is often used in the cryogenic environment because it exhibits high ductility and toughness even at low temperature. However, since austenitic steels generally exhibits low yield stress, some further strengthening is required to be used as structural materials for low temperature use.
