High Nitrogen Stainless Steel

摘要

A study was conducted to clarify the mechanical properties and stress corrosion cracking (SCC) resistance of high nitrogen stainless steel (HNSS) plates, produced by powder metallurgy rapid solidification process. It was found that the HNSS was highly workable and the yield strength, ultimate tensile strength, hardness, elongation, fracture toughness, and fatigue behavior were influenced by high nitrogen concentration and cold-work. Furthermore, the HNSS, annealed or cold-worked, was immune to SCC.
