UNS S31803

Duplex stainless steel UNS S31803 Nuts have two-phase, 5 to 6% nickel alloy steel, ferrite, 3% molybdenum, austenitic 22% chromium. It is one of the most extensively used graded duplex stainless steel. These stainless steel nuts are characterized by their elevated yield strength. Their characteristics are even double from standard steel grades of austenitic steel. They also exhibit fine resistance in situations of stress corrosion pitting, crevice & cracking along with better corrosion resistance in other severe environments. Their fatigue strength is also very good in all extreme conditions. The Duplex stainless steel UNS S31803 Nuts also exhibits fine strength against fatigue along with terrific resistance to counter stress corrosion crevice, cracking, pitting, erosion etc.


Duplex stainless steel UNS S31803 Nuts show their utilities in Chemical processors and the pieces of equipment of transport and storage firms. The types of equipment of gas and oil explorations like pipes, heat exchangers and tubes also utilize these nuts. Their workability in tough chloride environments also remains unaltered. Because of their appropriate contents of nitrogen, chromium and molybdenum give this material an excellent ability to withstand corrosion in every severe condition of working.
