254SMo stainless steel is known for its excellent corrosion resistance and is suitable for halide and acidic environments. Its unique alloy design reduces the risk of intergranular corrosion, enhances the corrosion resistance, and is widely used in chemical industry, desulfurization, environmental protection and other fields, becoming an important material in modern industry.
254SMO is an austenitic stainless steel. Due to its high molybdenum content, it has very high resistance to spot corrosion and crevice corrosion. This grade of stainless steel was developed for use in halogenated environments such as seawater. 254SMO also has good resistance to uniform corrosion. Especially in acids containing halides, the steel is superior to ordinary stainless steel. Its C content is <0.03%, so it is called pure austenitic stainless steel (<0.01% is also called super austenitic stainless steel). Super stainless steel is a kind of special stainless steel, first of all, different from ordinary stainless steel in chemical composition, it refers to a high-alloy stainless steel containing high nickel, high chromium, high molybdenum. One of the more famous is the 254SMo containing 6%Mo, this kind of steel has very good local corrosion resistance, in seawater, inflation, there are gaps, low speed erosion conditions, has good pitting resistance (PI≥40) and better stress corrosion resistance, is a substitute material for Ni-based alloys and titanium alloys. Secondly, in the performance of high temperature or corrosion resistance, it has more excellent high temperature or corrosion resistance, and is irreplaceable in 304 stainless steel. In addition, from the classification of stainless steel, the metallographic structure of special stainless steel is a stable austenitic metallographic structure.
Because this special stainless steel is a high-alloy material, it is quite complex in the manufacturing process, and generally people can only rely on traditional processes to manufacture this special stainless steel, such as perfusion, forging, calendering and so on.
