254SMO overview: 254SMO is a high-mo austenitic stainless steel with high corrosion resistance and crevice corrosion resistance. This brand of stainless steel is developed and developed for use in environments such as seawater containing halides. The corrosion resistance of 254SMO in the acidic solution and oxidized halide solution, such as pulp bleaching production, is comparable to that of the most corrosion-resistant nickel-base alloy and titanium alloy.
