Wai Nickel Alloys, a top-notch manufacturer and supplier located in Naypyidaw, Myanmar, specializes in high-quality Super Duplex Steel S32750 Bolts. These bolts are crafted for exceptional strength, corrosion resistance, and reliability, even in the toughest environments. Made from premium Super Duplex S32750 alloy, they shine in seawater, chemical, and high-pressure situations. Thanks to their balanced austenitic-ferritic structure, these bolts resist pitting, crevice corrosion, and stress corrosion cracking remarkably well. With impressive tensile strength and toughness, they’re perfect for offshore platforms, marine structures, oil refineries, and the chemical processing industry.
Super Duplex Steel S32750 Bolts are mainly made up of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–4%), and Iron, along with small amounts of Tungsten, Copper, Nitrogen, and Manganese. This unique blend creates a microstructure that boasts exceptional tensile strength (800–1000 MPa) and yield strength (~550 MPa). These bolts are known for their high impact toughness, fatigue strength, and resistance to chloride stress corrosion. They hold their mechanical stability even in high temperatures and harsh environments, ensuring they perform reliably for fastening applications in both industrial and marine settings.
