At Mitchell Stainless in Hamilton, New Zealand, we specialise in supplying stainless steel fasteners that perform in extreme environments. Our Stainless Steel 314 Bolts are designed for applications where very high temperatures and oxidation resistance are critical. Known for their reliability in intense heat, these bolts are supported by Mitchell Stainless’ strong focus on quality and local service. We work closely with customers across industrial and engineering sectors to provide fastening solutions they can trust, even in the most demanding conditions where standard stainless grades are simply not enough.
Stainless Steel 314 Bolts are manufactured from an austenitic stainless steel alloy with very high chromium and nickel content. This composition provides exceptional resistance to oxidation and scaling at extremely elevated temperatures. The material maintains good strength, toughness, and structural stability under prolonged heat exposure. Compared to other heat-resistant stainless grades, 314 offers superior high-temperature performance, making it suitable for applications where mechanical integrity must be retained in severe thermal environments.

After manufacturing Stainless Steel 314 Bolts, our quality control team tests these bolts with a rigorous destructive and non-destructive test using modern tools and techniques to ensure the reliability and strength of the product. We closely inspect each bolt for corrosion resistance dimensional accuracy, and performance. Once tested the bolts are packed safely with high-quality materials to prevent any damage while in transit. We ensure on-time and efficient delivery to our customers, adhering to the deadlines without any compromise. Moreover, all the relevant documentation, including certificates of compliance, is given along with delivery so that one has total trust in the product.
Stainless Steel 314 Bolts are commonly used in extreme high-temperature applications. Typical uses include furnaces, kilns, radiant tubes, heat treatment equipment, and petrochemical processing plants. They are also suited to power generation facilities, industrial burners, and thermal processing systems operating at very high temperatures. At Mitchell Stainless, we supply 314 bolts for specialised engineering projects where failure is not an option. Their outstanding heat and oxidation resistance make them a dependable fastening solution for the most demanding industrial environments.
