Elucidating the role of secondary cryogenic treatment on mechanical properties of a martensitic ultra-high strength stainless steel

Cryogenic treatment (CT) has been proved to be a critical process of the iron-based alloys. A unique series of processes including two steps of CTs are utilized for the treatment of Ferrium S53 ultra-high strength stainless steel. In the current work, the role of the secondary cryogenic treatment on the mechanical properties and corresponding microstructure of Ferrium S53 ultra-high strength stainless steel was investigated. The results indicate...
