Duplex Steel UNS S31803 Instrumentation Fittings are characterized by their lasting strength and increased resistance to corrosion. These components boast an impressive chemical composition of chromium, nickel, nitrogen, molybdenum, and manganese, each imparting its unique properties. Chromium provides superior corrosion resistance, while nitrogen boosts the steel's mechanical strength and austenitic microstructure. Molybdenum improves pitting resistance and further enhances the material's resistance to corrosion, making it ideal for use in high-pressure applications deemed prone to wear and tear. Meanwhile, manganese helps ensure that the fittings will remain durable over time with minimal susceptibility to oxidation. As a result of its varied composition, Duplex Steel UNS S31803 Instrumentation Fittings can be relied on as economic components designed for extreme temperature or pressure conditions.
Duplex Steel UNS S31803 Instrumentation Fittings are an ideal choice for various applications due to their strength and corrosion resistance. They are instrumental in the petrochemical, oil & gas, food processing and chemical engineering industries which have highly corrosive environments. The UNS S31803 grade steel has high mechanical strength and excellent resistance to chloride-based stress corrosion cracking. It also offers an improved mechanical resistance compared to other stainless steel grades. In addition, it has excellent resistance to erosion-corrosion fatigue and scaling and is weldable with common arc welding processes. As such, these instrumentation fittings are suitable for use in large-scale and specialized applications where corrosion must be managed effectively.
