George Metals, based in Houston, USA, is a well-respected manufacturer and supplier of Duplex Steel S31803 Bars and Rods. These products are crafted to deliver an impressive mix of strength, toughness, and resistance to corrosion. Thanks to its unique dual-phase microstructure of austenite and ferrite, S31803 duplex stainless steel stands out for its exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. George Metals offers S31803 bars and rods in a variety of sizes and lengths, all compliant with ASTM A276 and other international standards. These materials find extensive use in industries like oil & gas, marine, desalination, petrochemical, and construction, where maintaining structural integrity in harsh conditions is crucial.
The Duplex Steel S31803 Bars and Rods from George Metals are made up of roughly 21–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and 0.08–0.20% nitrogen, with iron making up the rest. This alloy is known for its impressive mechanical strength and resistance to localized corrosion. It boasts a yield strength of at least 450 MPa and a tensile strength around 620 MPa, along with excellent impact resistance. Typically, these bars are delivered in a solution-annealed and water-quenched state, ensuring the best phase balance and corrosion protection. The microstructure enhances durability, making these bars perfect for high-load applications and aggressive chemical environments.
