Duplex Steel S31803/S32205 Round Bar & Rods offer exceptional performance in challenging environments due to their balanced microstructure of austenite and ferrite phases. Manufactured per ASTM A276 / A479 and ASME SA276 / A479 standards, these round bars and rods are suitable for a variety of industrial applications requiring high strength and excellent corrosion resistance. Available in dimensions ranging from 14mm to 300mm in diameter and lengths from 50 mm up to 6 meters, these bars are offered in multiple forms including round, square, hex, rectangle, billet, ingot, and forging. Known for superior resistance to chloride stress corrosion cracking, pitting, and crevice corrosion thanks to their chromium, molybdenum, and nitrogen content, Duplex Steel S31803/S32205 bars are ideal for chemical, petrochemical, oil & gas, and marine industries. They provide good weldability and formability but are not recommended for continuous use above 300°C or below -50°C due to potential microstructural brittleness. Hot working is best performed between 954°C to 1149°C to optimize mechanical properties. These rods are widely available in hot rolled, cold rolled, polished, and forged finishes, ensuring adaptability to diverse manufacturing needs.
