Adinox Overseas is a brands name in the industry of industrial fasteners, which produce the best quality of SMO 254 Fasteners to go with the greatest demand and of the most rigid engineering order. These fasteners are made out of SMO 254 stainless steel that is of super austenitic grade and also known by the name UNS S31254 and ASTM A479.
This alloy is an extremely pitting and crevice corrosion resistant and stress corrosion cracking resistant to chloride environments, and is therefore suited to marine, chemical, petrochemical and offshore environments. With an exceptional combination of high molybdenum (6%) and nitrogen content, SMO 254 Fasteners exhibit outstanding resistance to crevice and pitting corrosion even in environments with high concentrations of chlorides and halides.

Adinox Overseas is determined to introduce corrosion resistant SMO 254 Bolts, Nuts, Washers, Studs, Screws and other types of fastening components that will register good performance under severe pressure and heat. Such fasteners are common especially in the industries that handle high levels of halides, brines and organic acids. The distinct list of contents SMO 254 contented with high amounts of chromium, nickel, molybdenum, and nitrogen gives a critical balance of hardness and corrosion resistance that being a better substitute to typical stainless steels, 316L or 904L.
