hex bolt DIN931 933 254SMO hex bolt
254 SMO bolts are made from (UNS S31254) austenitic stainless steel which is very resistant to pitting and crevice corrosion due to its high molybdenum content. This metal is designed for use in halide-containing environments, such as seawater.
254 SMO also has good uniform corrosion resistance, superior to conventional stainless steels, especially in halide-containing acids. Meanwhile, 254SMO is an austenitic stainless steel designed for maximum resistance to pitting and crevice corrosion. 254SMO fasteners contain high levels of chromium, molybdenum and nitrogen and are especially suitable for use in high chlorine environments such as brackish seawater pulp mill bleach plants and other high chlorine process streams.
