What is Stainless Steel? A Brief History of Stainless SteelThe birth of steel goes back about 4000 years when Development of Lean Duplex Stainless Steels (LDSS) with Low-Ni and Ni-free varieties of duplex stainless steels (DSSs) have been successfully developed for the first time on laboratory scale in SAIL.The alloy compositions for Ni-free and low-Ni ( A Brief History Of The Development Of Duplex Stainless Steellt;1.5 wt%) DSSs were evolved through formulation of appropriate chromium and nickel equivalents to achieve an optimum phase balance of 55 vol% austenite and 45 vol% ferrite in stainless steel microstructures.Development history of duplex stainless steel - YaangDuplex stainless steel,which combines many beneficial properties of ferritic and austenitic stainless steels,was originally developed in the early 1930s.The initial duplex stainless steel provides good performance characteristics but has limitations under welding conditions.
