Duplex Steel 2205 Bolts are made from an alloy with a balanced microstructure of austenite and ferrite. The composition includes chromium, nickel, molybdenum, and nitrogen, providing superior corrosion resistance and mechanical strength. High chromium and molybdenum content enhance resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, these bolts offer high tensile and yield strength, excellent toughness, and good fatigue resistance. They perform reliably under fluctuating loads, high pressure, and moderate-to-high temperature conditions, ensuring long-term durability.

Duplex Steel 2205 Bolts are widely used with nuts and studs in industries requiring secure and corrosion-resistant fastening. Common applications include oil and gas facilities, petrochemical plants, chemical processing equipment, offshore platforms, marine structures, and power generation units. They are also used in pipelines, heat exchangers, pressure vessels, and desalination plants. Due to their excellent resistance to chloride-induced corrosion and harsh environments, Duplex Steel 2205 Bolts are ideal for flanged joints, valves, pumps, and structural assemblies where operational safety, durability, and long-term reliability are critical.
