Duplex Steel Stud Bolts are made up of about 22–25% chromium, 4–7% nickel, 3–5% molybdenum, along with nitrogen, manganese, and the balance being iron. This well-balanced microstructure of austenite and ferrite gives them exceptional mechanical strength and resistance to localized corrosion. They boast a tensile strength ranging from 600–800 MPa, impressive yield strength, and good elongation. These bolts maintain their toughness even at low and high temperatures. Their strong resistance to chloride-induced stress corrosion cracking makes them a reliable choice for marine, chemical, and offshore applications where durability is crucial.
Duplex Steel Stud Bolts are widely utilized in industries that demand outstanding corrosion resistance and strength. They are perfect for offshore platforms, chemical processing equipment, heat exchangers, pressure vessels, and seawater systems. In oil and gas refineries, they ensure safe operation under high pressure and harsh conditions. Power generation plants and desalination facilities also depend on these bolts for their durability and resistance to stress cracking. Their versatility makes them ideal for marine engineering, food processing, and more.
