Duplex steel bolts are made from a balanced microstructure of austenitic and ferritic stainless steel, typically containing chromium, nickel, molybdenum, and nitrogen. This unique composition provides high tensile strength, excellent yield strength, and superior resistance to stress corrosion cracking. Duplex steel offers good toughness, fatigue resistance, and impact strength while maintaining excellent corrosion resistance in chloride-rich and harsh environments. These bolts perform reliably under high pressure, heavy loads, and fluctuating temperatures.

Duplex steel bolts are widely used in applications where both strength and corrosion resistance are critical. They are commonly used in oil and gas platforms, offshore structures, and marine equipment due to their resistance to seawater and chlorides. In chemical processing plants, duplex bolts are used for reactors, pipelines, and pressure vessels. They are also suitable for construction, desalination plants, power generation, and heat exchangers. Their durability, high load-bearing capacity, and long service life make duplex steel bolts ideal for demanding industrial environments
