Abstract: Austenitic stainless steel is with excellent low temperature toughness. The low tem-
perature performance characteristics of austenitic stainless steel were given. Analysis of impac
factors of the low-temperature properties of austenitic stainless steel was made, and the proposal
for design of different types of austenitic stainless steel was given as we
