Hamad Fasteners, located in Riyadh, Saudi Arabia, has built a solid reputation as a reliable manufacturer and supplier of high-performance fasteners tailored for tough industrial settings. Our Duplex Steel Nuts are perfect for applications that demand not only outstanding mechanical strength but also top-notch corrosion resistance. These fasteners find their place in various industries, including oil and gas, petrochemical, marine, desalination, and structural engineering. Crafted to meet international standards, our Duplex Steel Nuts guarantee durable and dependable fastening, even in the most corrosive or high-stress environments.
Made from austenitic-ferritic stainless steel, Duplex Steel Nuts typically contain about 22–25% chromium, 4–7% nickel, and 3–5% molybdenum, depending on the specific grade. This unique dual-phase microstructure gives them impressive tensile strength (usually between 620–900 MPa) and exceptional resistance to stress corrosion cracking, pitting, and crevice corrosion. Plus, these nuts maintain good toughness and weldability. Their superior mechanical properties make them stronger than regular austenitic stainless steels while providing enhanced corrosion resistance in environments with chloride exposure.
