The Fasteners Mart, which is located in Mumbai, India, is a reliable manufacturer and supplier of high-performance fasteners suitable for challenging industrial applications. One of their high-end products is SMO 254 Bolts, which are made from austenitic stainless steel that has high strength and resistance to corrosion. They are usually hexagonal in shape and meet international standards of durability and performance. SMO 254 (UNS S31254) finds special application in marine and chloride-contaminated environments because of its molybdenum content, and hence these bolts are perfect for harsh service conditions.
SMO 254 Bolts consist of high percentages of chromium (20%), nickel (18%), and molybdenum (6%), with the addition of nitrogen and trace quantities of copper. This characteristic combination confers enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking. They exhibit a high tensile strength of 650 MPa mechanically and good impact toughness. Physically, they show very good weldability, good ductility, and retain strength at high temperatures, which makes them appropriate in aggressive and corrosive environments.
