Vision Alloys is a trusted Duplex Steel UNS S32205 Fasteners manufacturer and supplier in Mumbai, India. Known for their high strength, corrosion resistance, and excellent fatigue performance. We offer a wide range of duplex steel fasteners, including nuts, bolts, studs, washers, and custom solutions, all of which find widespread use in critical industrial applications. Marine, oil & gas, petrochemical, and infrastructure sectors commonly choose these S32205 fasteners, built to withstand harsh environments. With years of industry expertise, we deliver dependable fastening components engineered for precision and long-term use.
Each Duplex Steel S32205 nut and bolt is crafted from a nitrogen-enhanced duplex alloy composed of around 22% chromium, 5–6% nickel, 3% molybdenum, and trace nitrogen. This balanced composition provides them with exceptional resistance to general corrosion, erosion, and chloride stress corrosion cracking. Our S32205 fasteners are compliant with the ASTM A182, ASTM A479, ASME SA182, and EN 1.4462 standards. For seamless trade and documentation, these products are classified under HSN Code 731815. We follow strict quality assurance processes to guarantee that each quantity meets the highest standards of metallurgical and dimensional precision.
These S32205 Duplex Steel bolts, nuts, and washers are widely used in industries such as desalination plants, heat exchangers, chemical processing lines, pressure vessels, and offshore installations. Hex bolts, hex nuts, lock gaskets, socket head screws, threaded rods, and stud bolts comprise our assortment. The S32205 Duplex steel fasteners are available in both metric and imperial dimensions, with threading options including UNC, UNF, and metric coarse. Their sizes range from M6 to M64. Custom fasteners can also be manufactured based on client drawings or relevant industry standards.
All fasteners are thoroughly tested for tensile strength, corrosion resistance, and dimensional accuracy. Vision Alloys guarantees complete transparency by providing mill test reports, third-party inspection documents, and compliance documentation, in addition to being ISO certified. The S32205 duplex nut bolts price typically varies from $0.25 to $14 per piece, contingent upon the type, coating, and dimension. We provide timely deliveries and volume discounts to meet the needs of large-scale industrial operations without sacrificing quality.
