UNS S31803 is ferritic-austenitic microstructure duplex steel. The alloy contains approximately 40–50 ferrite in its annealed state. The duplex microstructure combines the strength of ferritic steels with the corrosion resistance of austenitic steels. The metal is frequently employed as a viable remedy for chloride-induced stress cracking. The alloy has excellent resistance to corrosion in saltwater and most sulfuric acid concentrations. Furthermore, it is sulfide stress corrosion cracking resistant (sour-gas environments). Duplex stainless steel grades are up to twice as robust as austenitic and ferritic stainless steel grades in terms of strength. Duplex stainless steel valves are more formable under pressure and have a longer lifespan than ferrite types.

Global Steel assures you that these products are made to the highest possible quality standards. Only the best raw materials are used to make these valves. Duplex stainless steel valves are one type of industrial valve in high demand. Because of the grade’s ability to be solution treated but not thermally toughened, it can be used in a variety of applications. Duplex Steel UNS S31803 valves can be used in harsh circumstances. Many sectors, such as the chemical industry, oil and gas industry, petrochemical industry, power generation industry, sugar industry, food processing industry, paper and pulp industry, and offshore and onshore services use it. Global Steel delivers all types of products with complete safety and correct packing.
