At Mitchell Stainless in Hamilton, New Zealand, we supply stainless steel fasteners built for demanding conditions. Our Stainless Steel 304H Bolts are designed for applications where higher temperatures and consistent strength are essential. With a higher carbon content than standard 304 grades, these bolts provide added confidence in heat-exposed environments. Backed by Mitchell Stainless’ reputation for quality and local expertise, our 304H bolts are supplied to customers who value reliability, performance, and practical support. They are a dependable choice for industrial projects where conditions push standard fasteners beyond their limits.
Stainless Steel 304H Bolts are manufactured from an austenitic stainless steel alloy containing chromium and nickel, with a higher carbon content than 304 and 304L. This increased carbon improves high-temperature strength and creep resistance. The material maintains good toughness, oxidation resistance, and structural stability under heat. Stainless Steel 304H remains non-magnetic in the annealed condition and performs reliably in elevated temperature environments where long-term mechanical integrity is required.
