DSS have high strength,high corrosion resistance and good welding properties.Comparing with the same corrosion resistance level austenitic stainless steel,DSS decrease largely Ni content and realize the thinning of thickness design to perfectly optimize properties and decrease costs.Now DSS have been widely used in many fields such as petroleum,chemical industry,paper production,shipbuilding,nuclear power, seawater desalting,vacuum salt production and architecture.Tisco have began the process development and product application research of DSS products from last century and gradually solved a lot of technical problems such as AOD nitrogen alloying control of various content DSS,high temperature deformation mechanism of thermal process,large deformation hot rolling process of coils,the effect of bad phase precipitated during hot treatment process on properties and high efficiency pickling of high Cr/Mo content DSS plates.The various alloy content DSS plates and wide cold rolling coils(3Re60,S32101,S32304, S31803,S32205,S32750 and SUS329J4L) were successfully developed and used in national important constructions,key industries and abroad projects.
