Noah Tubefittings is a well-respected manufacturer and supplier located in Kinshasa, Congo, specializing in top-notch **Duplex Steel Tube Fittings**. These fittings are celebrated for their impressive strength, resistance to corrosion, and durability, making them perfect for tough industrial settings. They’re crafted to ensure secure, leak-proof connections in instrumentation, hydraulic, and process systems that operate under high pressure and temperature. Made from high-quality Duplex Steel, these fittings offer a fantastic blend of mechanical strength and resistance to pitting, crevice corrosion, and stress corrosion cracking. With a focus on precision engineering and reliability, Noah Tubefittings’ Duplex Steel Tube Fittings are the go-to choice for critical applications.
The composition of Duplex Steel Tube Fittings primarily includes chromium (22–23%), nickel (4.5–6.5%), and molybdenum (2.5–3.5%), with nitrogen added to boost strength and corrosion resistance. They boast a tensile strength of about 620 MPa and a yield strength of around 450 MPa. Thanks to their dual-phase (austenitic-ferritic) structure, they offer remarkable toughness, fatigue resistance, and stability even in extreme pressure and temperature situations.
