Wai Nickel Alloys, located in Naypyidaw, Myanmar, has made a name for itself as a top-notch manufacturer and supplier of high-quality Super Duplex Steel Nuts. These nuts are designed to deliver outstanding strength, remarkable corrosion resistance, and top performance even in the toughest industrial settings. Thanks to cutting-edge technology and precise manufacturing processes, Wai Nickel Alloys guarantees that every product meets international quality and performance benchmarks. With a commitment to reliability, innovation, and customer satisfaction, the company provides durable and efficient Super Duplex Steel Nuts suitable for industries like chemical processing, marine, oil and gas, and construction.
Super Duplex Steel Nuts are made up of chromium (24–26%), nickel (6–8%), molybdenum (3–4%), and nitrogen, which gives them exceptional resistance to pitting, crevice, and stress corrosion cracking. They boast a tensile strength of around 800 MPa and a yield strength of about 550 MPa, along with excellent fatigue and impact resistance. The unique dual-phase microstructure, combining ferrite and austenite, ensures a perfect balance of strength and corrosion resistance, making them reliable in high-pressure, high-temperature, and chloride-rich environments.
