At Mitchell Stainless in Hamilton, New Zealand, we supply fastening solutions that balance strength, reliability, and real-world performance. Our Stainless Steel 316H Bolts are designed for applications where higher temperatures and mechanical strength are part of the job. With a higher carbon content than standard 316, these bolts deliver added confidence in demanding industrial environments. Supported by our knowledgeable local team, Mitchell Stainless ensures you receive quality products that meet your project requirements, along with practical advice from people who understand the pressures of working in challenging conditions.
Stainless Steel 316H Bolts are manufactured from an austenitic stainless steel alloy containing chromium, nickel, and molybdenum, with an increased carbon content compared to 316 and 316L grades. This higher carbon level improves high-temperature strength and creep resistance. The molybdenum enhances resistance to pitting and crevice corrosion, while the alloy maintains good toughness and oxidation resistance. These bolts perform well under elevated temperatures, offering dependable mechanical stability where heat and pressure are ongoing concerns.
