S22053 (022Cr23Ni5Mo3N) is a corrosion-resistant stainless steel, particularly suitable for equipment in chloride environments. It has a narrow composition range and is one of the most commonly used steel grades in duplex stainless steel. S22053 can not only be formed by cold and hot processing, but also has good welding performance. It can be used as a structural material to replace traditional 304 and 316 stainless steel applications.
