Duplex Steel Bolts are crafted from duplex stainless steel, a unique two-phase alloy that combines austenitic and ferritic microstructures. Their typical composition features chromium (around 21–23%), nickel (approximately 4.5–6.5%), molybdenum (about 2.5–3.5%), nitrogen, and iron as the balance. This well-balanced structure provides mechanical strength that is nearly double that of standard austenitic stainless steels. For instance, Duplex S32205 bolts exhibit a tensile strength of around 800 MPa and a yield strength of about 550 MPa, along with commendable elongation and toughness. They also offer excellent resistance to corrosion, pitting, and stress-corrosion cracking, even in aggressive environments.

Duplex Steel Bolts find extensive use in applications where strong fastening and corrosion resistance are crucial. In the oil and gas sector, they play a vital role in securing structural components on offshore platforms and drilling equipment. Their ability to withstand chloride-induced corrosion makes them a perfect fit for marine environments, including shipbuilding, seawater systems, and coastal infrastructure. Additionally, these bolts are utilized in chemical processing plants, power generation equipment, and desalination facilities, where they are exposed to aggressive conditions.
