Punit Fasteners is a reliable manufacturer and supplier of Duplex Steel Bolts 2205 in Delhi, India. These bolts are made from UNS S32205, a nitrogen-enhanced duplex stainless steel known for its high strength and excellent resistance to corrosion and stress cracking. Our Duplex 2205 Bolts meet ASTM A479 and A182 standards, ensuring strong performance in tough environments. Available in hex head, heavy hex, and other types, these bolts are commonly used in offshore, chemical processing, and structural engineering. Punit Fasteners guarantees precision machining and high-performance fasteners designed for demanding industrial conditions and critical joint integrity.
Duplex Steel 2205 Bolts (UNS S32205) consist of about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, giving them a balanced dual-phase structure. They show high tensile strength (620–880 MPa) and yield strength (around 450–550 MPa). The Brinell hardness is about 250, which helps resist impact, fatigue, and wear. Duplex 2205 resists chloride-induced pitting, crevice corrosion, and stress corrosion cracking. These bolts maintain their integrity at high temperatures and under stress, making them suitable for aggressive, high-pressure situations.
