Ayten Tube Fittings is a well-respected manufacturer and supplier located in Addis Ababa, Ethiopia, known for its top-notch Duplex Steel S2205 Tube Fittings. These fittings are designed for exceptional performance and durability, blending impressive strength with outstanding resistance to corrosion. They find applications across various industries, including chemical processing, marine, oil and gas, and power generation. Thanks to a well-balanced microstructure of austenite and ferrite, Ayten’s Duplex S2205 Tube Fittings offer remarkable protection against stress corrosion cracking, pitting, and crevice corrosion. Each fitting is meticulously crafted to adhere to international standards, ensuring they deliver leak-free and long-lasting performance even in the toughest environments.
Duplex Steel S2205 Tube Fittings are made up of about 22% chromium, 5–6% nickel, 3% molybdenum, along with trace amounts of nitrogen, manganese, and silicon. This carefully balanced composition grants them exceptional resistance to corrosion caused by chlorides and oxidation. The material boasts high mechanical strength, with a tensile strength of around 620 MPa and a yield strength of 450 MPa. It also maintains excellent toughness and fatigue resistance, even in sub-zero temperatures. Additionally, Duplex S2205 offers superior thermal conductivity and reduced thermal expansion, ensuring it remains stable and reliable in harsh industrial conditions.
