Themba Nickel Alloys, based in Cape Town, Cape Town, stands out as a top manufacturer and supplier of high-quality Duplex Steel S32205 Bolts. These bolts are designed to deliver exceptional strength, durability, and corrosion resistance, making them perfect for tough industrial settings. Crafted to meet international quality standards, they excel in applications where mechanical reliability and resistance to harsh chemicals and seawater are essential. Thanks to their unique duplex microstructure, which blends the properties of ferritic and austenitic stainless steel, Themba Nickel Alloys’ S32205 Bolts offer remarkable tensile strength, toughness, and resistance to stress corrosion cracking, pitting, and crevice corrosion, making them ideal for the chemical, petrochemical, marine, and offshore sectors.
Duplex Steel S32205 Bolts are made from a blend of iron, chromium, nickel, and molybdenum, with a touch of nitrogen. This alloy features a well-balanced duplex microstructure that provides a tensile strength ranging from about 690 to 850 MPa, a yield strength of 450 to 550 MPa, and an elongation of 20 to 25%. This composition ensures outstanding resistance to chloride-induced pitting and crevice corrosion, along with impressive fatigue strength. These bolts maintain their mechanical integrity even under high temperatures and pressures, and they are also easy to weld and machine, guaranteeing long-lasting and dependable performance in corrosive and high-stress environments.
