ASTM A182 F 44 S31254 Stainless Steel Pipe Tee Pipe Equal Or Reducing Fittings
254SMO / F44 / UNS S31254 / 1.4547 / X1CrNiMoCuN20-18-7
254SMO is an austenitic stainless steel. Because of its high molybdenum content, it has extremely high resistance to pitting corrosion and crevice corrosion. This grade of stainless steel is developed and developed for use in environments containing halide such as seawater. 254SMO also has good resistance to uniform corrosion. Especially in the acid containing halide, 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 special stainless steel. First of all, it is different from ordinary stainless steel in chemical composition. It refers to a high alloy stainless steel containing high nickel, high chromium, and high molybdenum. Among them is 254SMo with 6% Mo. This type of steel has very good local corrosion resistance. It has good pitting corrosion resistance (PI ≥ 40) and good performance under seawater, aeration, gaps, and low-speed erosion Stress corrosion resistance is a substitute for Ni-based alloys and titanium alloys. Secondly, in terms of high temperature resistance or corrosion resistance, it has more excellent high temperature resistance or corrosion resistance and is irreplaceable by 304 stainless steel. In addition, from the classification of stainless steel, the metallographic structure of special stainless steel is a stable austenite metallographic structure.
