At Hazlewood Fasteners, we specialize in manufacturing and supplying premium-quality Duplex Steel S32205 Bolts in Canberra, Australia. These bolts are engineered to deliver exceptional strength, corrosion resistance, and durability — even in the most demanding environments. Made from duplex stainless steel grade S32205, they combine the toughness of austenitic stainless steel with the strength of ferritic alloys. Duplex S32205 Bolts perform exceptionally well in applications exposed to chloride stress, seawater, and acidic environments. Trusted by industries like oil & gas, petrochemical, and marine engineering, these bolts ensure reliable fastening where both power and performance are critical.
Duplex Steel S32205 Bolts are composed of chromium (22%), nickel (5–6%), molybdenum (3%), and balanced iron, with trace amounts of nitrogen and manganese. This unique dual-phase microstructure offers excellent resistance to pitting, crevice corrosion, and stress cracking. The alloy provides a tensile strength of about 620 MPa and yield strength near 450 MPa, almost twice that of conventional stainless steels. It maintains outstanding mechanical stability at both low and high temperatures, ensuring excellent fatigue strength and extended service life in demanding industrial environments.
