Duplex Steel Fasteners are a balanced mixture of austenitic and ferritic structures with 22-25% chromium, 4-7% nickel, 3-5% molybdenum, and nitrogen composition. Duplex Steel Fasteners possess excellent pitting corrosion resistance, crevice corrosion resistance, and stress corrosion cracking resistance in chloride environments. Duplex Steel Fasteners are mechanically better with high tensile strength (up to 800 MPa), good yield strength (around 450 MPa), and good impact toughness. Their excellent resistance to fatigue and heat render them ideal for high-stress use in naval, chemical, and offshore services with a long-term operation in harsh environments.

Duplex Steel Fasteners are extensively applied in processes requiring high strength and adequate resistance to corrosion, especially under stringent conditions. They find maximum use in offshore platforms of oil rigs, marine applications, chemical process plants, desalination plants, and power plants. These fasteners are specifically best suited for use in heat exchangers, pressure vessels, pipelines, storage tanks, and structural parts for exposure to harsh chemicals or high-pressure conditions. Their crevice corrosion, stress corrosion cracking, and pitting resistance makes them highly reliable in chloride-rich environments. Duplex Steel Fasteners provide long-term strength and performance in harsh industrial applications across various industries.
Duplex Steel Fasteners at The Fasteners Mart are tested stringently, e.g., mechanical tests, chemical tests, and non-destructive tests, to ensure that they meet industry standards and client specifications. Each fastener is inspected for strength, size, and surface finish. For secure transportation, fasteners are securely packed in wooden crates, corrugated boxes, or special packaging based on requirements. Protective covering and proper labeling prevent corrosion, damage, and contamination during transit, ensuring the fasteners arrive at the stringent industrial applications in the optimal state.
The Fasteners Mart is a leading manufacturer and supplier of high-quality fasteners in Mumbai, India, with over 8 years of experience serving global industries.
