Duplex Steel Boiler Tubing is typically produced using grades like UNS S31803 and S32205, which feature a unique dual-phase austenitic-ferritic microstructure. The chemical makeup includes around 22% chromium, 5–6.5% nickel, 3% molybdenum, and nitrogen, giving it outstanding resistance to chloride stress corrosion, pitting, and crevice corrosion. These tubes are known for their high mechanical strength, with a minimum yield strength of 450 MPa and tensile strength reaching up to 620 MPa. They also excel in toughness, thermal conductivity, and weldability, all of which are crucial for high-efficiency boiler applications that experience thermal cycling and pressurized conditions.
