Wai Nickel Alloys, a leading manufacturer and supplier located in Naypyidaw, Myanmar, specializes in top-notch Super Duplex Steel Screws that are built for outstanding strength, corrosion resistance, and performance in tough environments. These screws are crafted using cutting-edge machining and heat-treatment techniques, ensuring they meet international standards for precision, reliability, and durability. With a perfect blend of high mechanical strength and remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, these screws are perfect for fastening applications in offshore, chemical, marine, and petrochemical industries, guaranteeing long-lasting stability, safety, and exceptional performance even in high-pressure, high-temperature, and corrosive conditions.
Super Duplex Steel Screws are made up of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), and a balanced mix of Iron, along with controlled amounts of Nitrogen, Manganese, and Silicon. This unique alloy composition provides impressive corrosion resistance, particularly in chloride and acidic environments. They boast a tensile strength ranging from 800 to 1000 MPa, a yield strength of about 550 MPa, and a density of 7.8 g/cm³. These screws are designed to offer excellent fatigue resistance, impact toughness, and thermal stability, making them ideal for high-stress and corrosive settings where both strength and durability are essential.
