Fasteners Mart, Mumbai, India, is a leading manufacturer and supplier of high-quality Duplex Steel 2205 Fasteners with high strength and very good corrosion resistance. The fasteners are designed to operate in challenging environments such as marine, chemical, and offshore applications, where chloride-induced corrosion resistance is necessary. With a commitment to precision, rigorous quality control, and prompt delivery, The Fasteners Mart serves industries worldwide with strong and reliable fastening products that ensure long-term performance and structural integrity in demanding conditions.
Duplex Steel 2205 Fasteners contain 22% chromium, 5-6% nickel, 3% molybdenum, and nitrogen, possessing a balanced austenite-ferrite microstructure. The composition provides adequate resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride media. From a mechanical properties standpoint, Duplex 2205 fasteners exhibit high tensile strength (upto 620–800 MPa) and yield strength (around 450 MPa), and they also exhibit excellent fatigue resistance and impact toughness. They are ideally suited for application in aggressive applications such as marine, chemical processing, and offshore markets for lasting durability and long-term reliability.
