Explanation

The structure in solution treatment state is martensite. After aging treatment at 480-630 ° C, precipitation precipitates imermetallif compound or carbon/nitride produces precipitation precipitation strengthening effect on martensitic stainless steel. Its carbon content is less than 0.1%, and precipitation strengthening effect is produced by adding elements such as copper, molybdenum, niobium, titanium and aluminum during aging. It is widely used in structural parts such as fasteners, valves, springs, blades, etc. that require medium temperature, high strength, high wear resistance and high corrosion resistance in aerospace, nuclear power and petrochemical industries.
