At Hazlewood Fasteners, we manufacture and supply superior-quality Stainless Steel 317/317L Stud Bolts in Canberra, Australia, built for environments that demand exceptional corrosion resistance and mechanical strength. These bolts are designed to perform reliably in chemical, marine, and high-moisture settings. The higher molybdenum content in SS 317/317L enhances resistance to pitting, crevice corrosion, and acid attacks. The low-carbon variant (317L) offers excellent weldability and prevents carbide precipitation. Whether used in refineries, paper mills, or food processing plants, Hazlewood Fasteners’ 317/317L Stud Bolts deliver long-lasting durability and consistent performance in even the harshest conditions.
Stainless Steel 317/317L Stud Bolts contain approximately 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, offering enhanced corrosion and oxidation resistance. Grade 317L, with its low carbon content, minimizes intergranular corrosion during welding. These bolts provide a tensile strength of about 515–620 MPa and yield strength around 205–240 MPa, maintaining excellent mechanical integrity under high stress and temperature. Their superior formability, toughness, and resistance to acids like sulfuric and phosphoric make them ideal for demanding industrial applications where both strength and corrosion protection are vital.
