254SMO Stainless Steel Bar Description

254SMO is a stainless steel originally used in seawater and other aggressive chloride environments. This grade includes a very high-end austenitic stainless steel; consisting primarily of 17.5 to 18.5 percent nickel, 19.5 and 20.5 percent chromium, 6 to 6.5 percent molybdenum, and. 18 to. 22 percent nitrogen. In this "super austenitic" chemistry, these specific levels of Cr, Ni, Mo and N give the 31254 impact toughness to resist cracking, pitting and crevice corrosion, and almost twice the strength of 300 series stainless steel.
