About 22–25% chromium, 4–6% nickel, 2.5–3.5% molybdenum, and nitrogen make up duplex steel bolts, which have a mixed austenite and ferrite microstructure. High mechanical strength and exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking are provided by this well-balanced structure. Even at very high temperatures, these bolts show exceptional toughness and durability thanks to their tensile strength of 620–880 MPa and yield strength of over 450 MPa. They are perfect for demanding industrial applications that require both structural integrity and long-term reliability because of their strength and resistance to corrosion.
In industries where strength and resistance to corrosion are crucial, duplex steel bolts are indispensable. Because of their remarkable performance in high-pressure, chloride-rich environments, they are extensively utilised in desalination plants, chemical processing facilities, offshore oil platforms, and subsea systems. They protect structural elements exposed to seawater in marine engineering. They are used in the infrastructure and construction industries for high-load joints and assemblies, particularly in humid or corrosive conditions. These bolts are essential to pulp and paper mills and power generation facilities because they are resistant to mechanical wear and chemical attack, guaranteeing long service life and operational safety.
