Elvis Nickel Alloys, a reputable manufacturer and supplier located in Houston, USA, specializes in top-quality Duplex Steel S31803 Forged Fittings that are perfect for high-pressure and highly corrosive settings. Crafted from UNS S31803, a nitrogen-enhanced duplex stainless steel, these fittings boast an impressive blend of strength and outstanding corrosion resistance. Thanks to their balanced austenitic-ferritic microstructure, they offer exceptional protection against stress corrosion cracking, pitting, and crevice corrosion, particularly in environments with chloride. Available in various types like socket weld, threaded elbows, tees, couplings, and unions, these fittings comply with international standards such as ASTM A182 and ASME B16.11, ensuring they deliver durability and performance in critical applications.
Duplex Steel S31803 Forged Fittings are made up of roughly 21–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and 0.14–0.20% nitrogen, with the rest being iron and trace elements. This alloy offers impressive tensile strength (≥620 MPa) and yield strength (≥450 MPa), along with good ductility and impact toughness. The dual-phase structure significantly boosts resistance to fatigue, intergranular corrosion, and chloride-induced cracking. These forged fittings also demonstrate excellent thermal stability, making them ideal for welding, machining, and high-pressure operations in challenging environments.
