At Mitchell Stainless in Hamilton, New Zealand, we provide stainless steel bars engineered for extreme high-temperature and demanding industrial applications. Our Stainless Steel 314 Bars are designed to retain strength, resist oxidation, and deliver reliable long-term performance in elevated heat environments. Ideal for furnaces, kilns, and thermal processing systems, these bars are used where durability and mechanical stability are critical. Backed by Mitchell Stainless’ commitment to quality and local expertise, 314 bars offer customers a dependable solution for industrial projects requiring superior heat resistance and structural integrity.
Stainless Steel 314 Bars are manufactured from a high-chromium and high-nickel austenitic stainless steel alloy. This composition provides excellent resistance to oxidation, scaling, and corrosion at extremely elevated temperatures. The bars maintain good tensile strength, toughness, and structural stability under prolonged heat exposure. Stainless Steel 314 retains its mechanical properties effectively in continuous high-temperature service, making it suitable for industrial applications that require long-term durability and reliable performance in severe thermal conditions.
