摘要
Spring steel (in wire or strip form) is produced from an austenitic stainless steel, the chromium content of which is sufficient to give the steel a metastable austenitic microstructure, by (1) annealing and (2) quenching under conditions to give it a wholly austenitic condition, followed by (3) a very substantial cold reduction which transforms its structure to an at least partially martensitic structure and produces increased hardness.
