Request For Our Latest Prices on Stainless Steel 310/310S Nuts in Canberra, Australia!
At Hazlewood Fasteners, we proudly manufacture and supply durable Stainless Steel 310/310S Nuts in Canberra, Australia—crafted for exceptional strength, heat resistance, and reliability in high-temperature environments. These nuts are made from an austenitic stainless steel alloy with a high chromium and nickel content, providing outstanding oxidation and corrosion resistance. The 310S variant, with lower carbon content, offers enhanced weldability and minimizes carbide precipitation. Ideal for use in industrial furnaces, chemical plants, and heat exchangers, Hazlewood Fasteners’ 310/310S Nuts deliver dependable fastening performance, long service life, and superior resistance to scaling and thermal stress.
Stainless Steel 310/310S Nuts contain approximately 24–26% chromium, 19–22% nickel, and a maximum carbon content of 0.25% (0.08% in 310S). This high-alloy composition offers excellent oxidation resistance up to 1100°C and good ductility at both high and low temperatures. With a tensile strength around 515 MPa and yield strength near 205 MPa, these nuts provide outstanding mechanical stability. 310 offers superior high-temperature strength, while 310S provides better weldability and reduced susceptibility to intergranular corrosion, making them suitable for continuous high-heat applications.
