Mumbai-based well-known manufacturer and supplier of quality Duplex Steel 2205 Bolts is Jyoti Steels. We are into providing long-lasting and corrosion-proof fastening products to the construction, marine, chemical, as well as the oil & gas industries. We design our 2205 Duplex Bolts for higher strength, reliability, and long-life performance in the toughest conditions. With state-of-the-art production methods, rigorous quality control, and effective logistics, Jyoti Steels strives to provide top-quality products and superior service to cater to the varied needs of customers both domestic and international.
Duplex Steel 2205 Bolts contain approximately 22.0–23.0% Chromium, 4.5–6.5% Nickel, 3.0–3.5% Molybdenum, up to 2.0% Manganese, and 0.14–0.20% Nitrogen. These components have very good corrosion resistance, particularly against crevice corrosion and pitting. Mechanically, they have about 620 MPa tensile strength, 450 MPa yield strength, and about 25% elongation. Physically, the density of the bolts is 7.8 g/cm³ and the melting point is in the range of 1350°C to 1450°C. Their double-phase (ferritic-austenitic) microstructure makes them perform exceedingly well under stress, high pressure, and corrosive conditions.

Duplex Steel 2205 Bolts are widely utilized in applications where strength and corrosion resistance are essential. These bolts are best suited for offshore platforms, subsea equipment, heat exchangers, pressure vessels, and pipelines in the oil and gas industry. They are also utilized in marine applications, desalination plants, paper and pulp processing, and chemical production. Due to their excellent resistance to chloride-induced corrosion and stress corrosion cracking, they are appropriate for coastal and high-humidity applications. They are also used in structural assemblies, heavy machinery, and architectural structures that need robust and low-maintenance fastening systems.
