The Fasteners Mart, which is a leading producer and distributor of Mumbai, India, exports and supplies high-strength Duplex Steel S31803 Bolts that are strong and corrosion resistant. The bolts are manufactured according to the stringent environments such as marine, chemical, and offshore environments and have superior quality and reliability. In focus with accuracy, quality monitoring, and guaranteed delivery, The Fasteners Mart distributes locally and globally to various industries. Our Duplex Steel S31803 Bolts provide lasting durability and make us a preferred partner for fastening solutions of high performance in numerous industries.
Duplex Steel S31803 Bolts contain 22% chromium, 5-6% nickel, 3% molybdenum, and impurities of nitrogen, giving a balanced austenite and ferrite microstructure. The alloy encourages pitting, crevice corrosion, and stress corrosion cracking resistance, particularly in chloride media. S31803 bolts, mechanically, possess a high yield point of around 450 MPa and tensile strength of 620–850 MPa, along with superior impact and fatigue characteristics. These traits are well-suited for demanding uses in the chemical, marine, and oil & gas industries, offering durability and long-term performance.

Duplex Steel S31803 Bolts have wide application in those industries where they have to offer high strength coupled with better corrosion resistance. Common applications are in the form of offshore oil and gas platforms, marine conditions, and chemical processing plants due to their resistance against chloride stress corrosion and pitting. They are also used in heat exchangers, pressure vessels, pipelines, and storage tanks handling aggressive chemicals. In addition, S31803 bolts are most apt for application in power plants, desalination plants, and marine construction projects. Their improved mechanical properties and corrosion resistance in aggressive environments make them an ideal choice for challenging fastening applications across various industries.
Duplex Steel S31803 Bolts at The Fasteners Mart are subjected to rigorous testing, i.e., mechanical, chemical, and non-destructive tests for maintaining conformity to high industry standards. Tensile strength, surface finishing, and dimensional checking are done on each bolt. Bolts are neatly packed in wooden crates, corrugated crates, or custom packaging according to client requirements for transportation safely. Proper labeling and protective packaging prevent damage, corrosion, and contamination in transit, and the bolts arrive at their destination in as good condition as when they were made.
