Mitchell Stainless, a trusted manufacturer and supplier in Hamilton, New Zealand, provides premium Stainless Steel 314 fasteners designed for high-temperature applications requiring excellent oxidation and corrosion resistance. 314 is an austenitic stainless steel alloy formulated for extreme heat environments, offering excellent scaling resistance and mechanical stability. Mitchell Stainless ensures that each fastener meets stringent quality standards, providing precise dimensions, consistent mechanical performance, and long-term durability. These fasteners are ideal for industrial, chemical, and high-temperature processing environments where strength, thermal stability, and corrosion resistance are critical for reliable performance.
Stainless Steel 314 fasteners are composed primarily of iron, with 24–26% chromium, 19–22% nickel, and small amounts of manganese, silicon, and carbon. This composition provides superior oxidation and scaling resistance at elevated temperatures, excellent high-temperature strength, and moderate corrosion resistance. Chromium and nickel ensure mechanical stability and toughness under extreme thermal conditions, while the balanced alloying maintains durability. These fasteners are suitable for demanding applications where high-temperature performance and long-term reliability are required, such as in furnaces, heat exchangers, and other high-heat industrial equipment.
