Type UNS S30200 plate is an austenitic chromium-nickel stainless steel, non-hardenable by thermal treatments. It may be cold worked to high tensile strengths with slightly lower ductility than Type 301. Its corrosion resistance is superior to that of UNS S30200 plate. Type UNS S30200 plate is essentially nonmagnetic in the annealed condition and becomes slightly magnetic when cold worked.
