At Mitchell Stainless in Hamilton, New Zealand, we supply stainless steel fasteners engineered for high-temperature and demanding industrial applications. Our Stainless Steel 314 Nuts are designed to withstand extreme heat while maintaining strength, oxidation resistance, and durability. Ideal for furnaces, kilns, thermal processing systems, and heavy industrial machinery, these nuts provide reliable fastening in severe conditions. Supported by Mitchell Stainless’ commitment to quality and local expertise, 314 nuts offer a dependable solution for projects requiring long-term performance, mechanical integrity, and corrosion resistance in high-temperature and industrial environments.
Stainless Steel 314 Nuts are manufactured from an austenitic stainless steel alloy with very high chromium and nickel content. This composition ensures excellent oxidation and scaling resistance at elevated temperatures, along with good corrosion resistance. The nuts provide high tensile strength, toughness, and structural stability under prolonged heat exposure. Stainless Steel 314 maintains mechanical performance and dimensional stability in continuous high-temperature service, making it suitable for industrial applications where durability, heat resistance, and reliable fastening are essential.
