S20910 stainless steel provides a combination of good corrosion resistance and strength not found in any other commercial material available in its price range. This austenitic stainless steel has corrosion resistance greater than that provided by types 316 and 316L, plus approximately twice the yield strength at room temperature in the annealed condition.
In addition S20910 stainless steel has very good mechanical properties at both elevated and sub-zero temperatures a well as outstanding cryogenic properties. And, unlike many austenitic stainless steels, 22-13-5 stainless steel can be heavily cold worked to enhance its yield strength and remain non-magnetic.
