  254SMO also has good resistance to uniform corrosion. Especially in acids containing halides, this steel is superior to ordinary stainless steel. Its C content is<0.03%, therefore it is called pure austenitic stainless steel (<0.01%, also known as super austenitic stainless steel). Super stainless steel is a special type of stainless steel, which differs from ordinary stainless steel in chemical composition. It refers to a high alloy stainless steel with high nickel, high chromium, and high molybdenum content. One of the most famous is 254SMo, which contains 6% Mo. This type of steel has excellent local corrosion resistance, good resistance to pitting corrosion (PI ≥ 40) and good stress corrosion resistance under conditions of seawater, inflation, presence of gaps, and low-speed erosion. It is a substitute material for Ni based alloys and titanium alloys. Secondly, in terms of high temperature or corrosion resistance, it has more excellent high temperature or corrosion resistance, which is irreplaceable for 304 stainless steel. In addition, from the classification of stainless steel, the metallographic structure of special stainless steel is a stable austenitic metallographic structure.
