Manufacturer, Supplier & Exporter of EN 1.4362 Spool
EN 1.4362, also known as X2CrNiN23‑4 or UNS S32304, is a lean duplex stainless steel grade widely used in industrial applications requiring both high strength and corrosion resistance. Its microstructure is roughly balanced between ferrite and austenite phases, which gives it a unique combination of mechanical strength, toughness, and resistance to stress corrosion cracking. Compared to traditional austenitic stainless steels like 304 or 316, EN 1.4362 offers nearly double the yield strength, making it an ideal choice for structural and pressure-bearing applications..
Chemically, EN 1.4362 contains approximately 22–24% chromium, 3.5–5.5% nickel, 0.05–0.20% nitrogen, along with small amounts of molybdenum and copper to stabilize its duplex structure. The presence of nitrogen significantly increases strength and enhances resistance to pitting and crevice corrosion, while low carbon content improves weldability and minimizes the risk of intergranular corrosion. This makes it particularly suitable for applications in chemical processing, water treatment, marine environments, and construction.
Mechanically, EN 1.4362 exhibits a 0.2% yield strength of 400 MPa or more, an ultimate tensile strength of 600–830 MPa, and elongation at break of ≥ 25%, offering an excellent combination of strength and ductility. Its hardness remains moderate, allowing it to be fabricated into spools, pipes, sheets, and flanges without compromising performance. These properties make it a versatile material for industries where both structural integrity and corrosion resistance are critical..
Corrosion resistance is a key feature of EN 1.4362. It demonstrates excellent resistance to stress corrosion cracking and performs comparably to 316L in many chloride-containing environments. Its Pitting Resistance Equivalent Number (PREN) ensures reliable performance in moderately aggressive chemical conditions. The duplex structure minimizes the risk of localized corrosion, making it suitable for industrial piping systems, pressure vessels, and marine infrastructure..
In fabrication, EN 1.4362 can be welded using standard methods such as TIG, MIG, and arc welding, and post-weld solution annealing helps restore its balanced microstructure. The material maintains stability across a wide service temperature range, typically –40°C to +250°C, and has a lower coefficient of thermal expansion than austenitic steels, reducing the risk of distortion in temperature-sensitive applications. Proper handling and certified material documentation are important to ensure the duplex properties are preserved during welding and forming processes..
