STAINLESS AND DUPLEX STEEL ROUND BARS

Stainless and duplex steel round bars are high-performance materials valued for their corrosion resistance and strength in industrial piping and structural applications.

Common grades like 304/304L and 316/316L offer good general corrosion resistance (PREN 18-24), tensile strengths 500-750 MPa, and availability in diameters 3-300mm, hot/cold rolled, peeled, or ground finishes per ASTM A276/A479. Ideal for shafts, valves, and fittings in chemical/marine settings.

UNS S32750 (2507 super duplex, F53) provides superior pitting resistance (PREN >40), minimum yield 550 MPa, tensile 800 MPa, and 15% elongation, in sizes 6-450mm diameter, lengths 100-6000mm, cold drawn/polished per ASTM A479/A276. Excels in offshore, sour service over 2205
