Duplex Steel Bolts are made of a mixture of ferrite and austenite. This combination creates a product with enhanced strength, corrosion resistance and temperature resistance when compared to other steel compositions. The most common composition is between 20-50% austenite and 70-50% ferrite. It contains a higher chromium, nickel and molybdenum content than many other regular bolts making it ideal for applications that require high levels of abrasion or corrosion resistance. Furthermore, Duplex Steel Bolts have greater yield and tensile strengths than standard stainless steel, making them great for use in construction projects or any application requiring strong bolting force.
Duplex steel bolts are an effective solution for many infrastructure projects. Their composition, comprised of ferritic and austenitic stainless steels, gives them superior strength, corrosion resistance, and longevity, making them an ideal choice for marine operations and a structural framework. They possess high tensile strength and ductility, making them ideal for heavy machinery and equipment use. Duplex steel bolts also boast excellent cryogenic properties – they remain stable at temperatures far below the freezing point of water without experiencing any severe deformation, making them ideally suited to industrial environments with extreme cold or heat. Beyond their functional capabilities, this bolt type is easily machinable as threads can be easily tapped directly into the head, providing a quick installation process. Additionally, duplex steel bolts offer good resistance to stress-corrosion cracking and can be used in various applications, from construction to mining operations.
