Table of Content
Duplex Steel S31803 / S32205 Round Bars are extremely strong stainless steel bars that are produced with a balanced combination of austenitic, and ferritic microstructures. It has good corrosion resistant properties, and is suitable in hostile environments where regular stainless steel is not suitable. Preston Pipes & Alloys is recognized for supplying high-quality UNS S31803 Round Bars, which are suitable for demanding projects. These bars are immune to pitting, crevice corrosion and stress corrosion cracking. It is commonly used in petrochemicals, oil and gas, chemicals, power plants, energy, pharmaceuticals, pulp and paper, food processing, aerospace, and refining industries. Their wear resistance, high strength and durability make them the first choice in both structural and mechanical applications.
The Duplex Steel S32205 Round Bar range includes diameters of 10 mm to 100 mm and lengths of 100 mm to 6000 mm. Available finishes include bright, black, and polished. Forms offered are round, square, hex, bush, rectangle, and flat. Known under the trade name SAF 2205 Duplex Stainless Steel Bar, these products come in surfaces like hot-rolled pickled, sand-blasted, cold-drawn, bright, polished, or hairline finish. Size tolerances are available in H8 to H13 and K9 to K12, or as per project needs. The shapes we manufacture include flat bars, square bars, round bars, rings, hollows, blocks, and custom shapes designed to meet specific requirements.
The duplex 2205 round bar alloy is composed of chromium, nickel, molybdenum, nitrogen, carbon, manganese, silicon, phosphorus and sulfur in precise quantities to provide it, with outstanding durability. The UNS S31803 Round Bar has a minimum yield strength of 450 MPa and a minimum tensile strength of 620 MPa. The density is around 7,805 kg/m³ and the elastic modulus is 200 GPa. The physical properties include a thermal expansion rate that makes it suitable for stability in high temperature circumstances, good thermal conductivity for transferring energy and an outstanding specific heat capacity. These features provide both mechanical, and thermal stress reliability, which suits the material for use in critical engineering components.
Each Duplex Steel S31803 Round Bar goes through strict quality testing, which includes chemical analysis, mechanical testing and third-party checks. Each batch is traceable with documentation and inspection reports. Packing is done according to industry standards with the use of wooden boxes, plastic bags, and steel strip bundles, or as per customer requirements to ensure delivery safety. Precision in manufacturing and quality assurance ensures that each bar meets exact specifications for long-term performance. For reliable and durable round bars built for demanding environments, choose high quality Duplex Steel S31803/S32205.
