Brian Fasteners is a preeminent Houston-based Duplex Steel Stud Bolts 2205 manufacturer and supplier of high-strength and corrosion-resistant fasteners for rigorous environments. Duplex 2205 (UNS S32205/S31803) is the largest-sold duplex stainless steel grade with superior strength and corrosion resistance. Our precision-made Duplex 2205 Stud Bolts to ASTM A182/A479 specifications ensure reliability in chemical processing, marine, and oil & gas industry applications. Brian Fasteners supplies fasteners that exhibit superior performance in high-pressure, corrosive, and structurally challenging situations in all major global industries.
Duplex 2205 Stud Bolts will have 22% chromium, 5–6.5% nickel, 3% molybdenum, and nitrogen to increase the strength of the alloy. They provide great resistance to crevice corrosion and pitting. The alloy has tensile strength of 95–115 ksi, yield strength of 65–80 ksi, and Rockwell hardness of about B100. The duplex microstructure provides greater mechanical strength and stress corrosion resistance especially in chloride-bearing environments. These bolts are a cost-efficient and long–lasting substitute for high-nickel alloys and work in dynamic loading well.
