Mitchell Stainless is a reliable manufacturer and supplier of top-notch Stainless Steel 316L fasteners based in Hamilton, New Zealand. With a strong focus on precision engineering and adherence to international quality standards, the company provides durable, corrosion-resistant fastening solutions tailored for a variety of industrial applications. Known for their outstanding performance in tough and corrosive settings, especially where chloride exposure is prevalent, Mitchell Stainless’s fasteners are backed by advanced manufacturing techniques, rigorous quality control, and dependable supply capabilities. They cater to industries like marine, chemical processing, construction, and food processing, both in New Zealand and around the globe.
Stainless Steel 316L fasteners are primarily made of iron, containing about 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, along with a low carbon content of a maximum of 0.03%. This low carbon content helps reduce carbide precipitation and enhances weldability. In terms of mechanical properties, 316L fasteners boast good tensile strength, excellent ductility, and toughness, even in low temperatures. They also offer remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive environments.
