Tanvir Nickel Alloys is a leading manufacturer and supplier of Duplex Steel 2205 Stud Bolts in Cairo, Egypt, offering high-quality fasteners engineered for superior strength, durability, and corrosion resistance. These stud bolts are precision-manufactured to meet international standards, ensuring reliable performance in demanding industrial and marine environments. Tanvir Nickel Alloys’ Duplex Steel 2205 Stud Bolts are widely used in oil & gas, chemical, petrochemical, and desalination industries, where exposure to corrosive media, high pressure, and extreme temperatures requires fasteners that maintain integrity and long-term reliability.
Duplex Steel 2205 Stud Bolts are composed of approximately 22% chromium, 5–6% nickel, 3% molybdenum, with the remainder iron, and small additions of nitrogen to enhance mechanical strength and corrosion resistance. They exhibit a high tensile strength of 620–850 MPa, excellent yield strength, and superior resistance to stress corrosion cracking, pitting, and crevice corrosion. These stud bolts also offer good ductility, toughness, and weldability, making them suitable for high-pressure and corrosive applications.
