Wai Nickel Alloys, a top-notch manufacturer and supplier located in Naypyidaw, Myanmar, specializes in high-quality Super Duplex Steel Washers. These washers are celebrated for their exceptional corrosion resistance, mechanical strength, and reliability, even in the toughest environments. Crafted with cutting-edge technology and premium raw materials, they adhere to international standards for precision and durability. Designed to ensure secure fastening, Super Duplex Steel Washers excel in resisting stress corrosion cracking, pitting, and oxidation. They are perfect for heavy-duty industrial applications and are commonly found in offshore, chemical, marine, and oil & gas industries, where strength and longevity are essential.
Super Duplex Steel Washers are made up of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), and a balanced amount of Iron, along with small traces of Nitrogen, Manganese, and Silicon. This unique blend gives them remarkable corrosion resistance and mechanical strength, boasting a tensile strength of 800–1000 MPa and a yield strength of around 550 MPa. With a density of 7.8 g/cm³, they also feature high impact toughness and excellent resistance to chloride-induced corrosion. Super Duplex Washers maintain outstanding dimensional stability and performance, even under extreme pressure and temperature conditions, making them ideal for critical fastening applications.
