Duplex Steel 2205 Fasteners are high-performance components made from a specialized duplex stainless steel that combines the strengths of both ferritic and austenitic steels, offering exceptional strength and superior corrosion resistance. Renowned for their durability, these 2205 duplex stainless steel fasteners provide up to 97 ksi minimum yield strength and 131 ksi minimum tensile strength, making them nearly twice as strong as standard austenitic steel fasteners. 

They are versatile, suitable for demanding environments such as chemical processing, oil and gas, and marine applications, thanks to their ability to withstand high temperatures and pressures. Composed of 22% chromium, 4.5% nickel, and 3% molybdenum, duplex SS 2205 fasteners are engineered for robust mechanical properties and come in various types, including bolts, nuts, screws, and studs, meeting industry standards like ASME SA 182 and SA 240 for reliable performance across diverse applications.
