Stainless Steel Plate
The types and contents of chemical elements in 254SMO stainless steel have been precisely proportioned and optimized, giving it excellent corrosion resistance, high temperature strength and processing performance. Therefore, it has been widely used in petroleum, chemical industry, marine engineering and other fields.

254 SMO 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.
