Wai Nickel Alloys, a reputable manufacturer and supplier located in Naypyidaw, Myanmar, specializes in high-quality Super Duplex Steel Threaded Rods designed for exceptional strength, corrosion resistance, and long-lasting durability. Crafted with precision through advanced metallurgical techniques, these threaded rods adhere to international standards for both performance and dimensional accuracy. Renowned for their remarkable resistance to pitting, crevice corrosion, and stress cracking, Super Duplex Steel Threaded Rods provide impressive mechanical strength and toughness, even in challenging environments. They find extensive use in chemical, marine, oil & gas, and offshore applications where reliability and resilience against extreme conditions are essential.
Super Duplex Steel Threaded Rods are mainly made up of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), and a balanced amount of Iron, along with trace elements of Nitrogen, Manganese, and Silicon. This unique composition guarantees excellent corrosion resistance and high tensile strength, reaching up to 800–1000 MPa. They have a density of 7.8 g/cm³, a yield strength of about 550 MPa, and outstanding impact toughness at both high and low temperatures. These rods maintain their mechanical stability in chloride-rich and acidic environments, providing remarkable resistance to oxidation and fatigue under demanding service conditions.
