As a premier Duplex Steel Bolts Manufacturer in the Cape Town, we create bolts with a carefully balanced chemical composition, typically featuring 22–23% Chromium, 4.5–6.5% Nickel, 3–3.5% Molybdenum, and low carbon content. These bolts boast impressive mechanical properties, including high tensile strength (620–880 MPa), yield strength (~450 MPa), and remarkable hardness and elongation. The unique microstructure of duplex stainless steel, which combines austenitic and ferritic phases, provides enhanced corrosion resistance, stress corrosion cracking resistance, and toughness, making them perfect for critical and high-pressure applications across various industrial sectors.
