Mitchell Stainless, a trusted manufacturer and supplier in Hamilton, New Zealand, offers high-quality Stainless Steel 301 fasteners designed for applications requiring good corrosion resistance, high strength, and excellent formability. This austenitic stainless steel fastener provides a balance of toughness, ductility, and durability, making it ideal for structural, mechanical, and general-purpose fastening applications. Mitchell Stainless ensures that each fastener meets stringent quality standards, with precise dimensions and consistent mechanical performance. 301 fasteners are suitable for industrial, commercial, and architectural applications where reliable fastening, durability, and moderate corrosion resistance are essential.
Stainless Steel 301 fasteners are composed primarily of iron, with 16–18% chromium, 6–8% nickel, and small amounts of manganese, silicon, and carbon (max 0.15%). This composition provides good corrosion resistance, high tensile strength, and excellent ductility. The combination of chromium and nickel ensures resistance to oxidation and environmental corrosion while maintaining formability and weldability. 301 fasteners are suitable for applications requiring mechanical performance, moderate corrosion resistance, and long-lasting durability in industrial, commercial, and architectural environments.
