Weston Stainless, Midland, UK, is a reliable distributor of stainless steel products of highest quality, with specialization in precision-made fasteners for the different industries. Of their products, Stainless Steel 304H Stud Bolts are extensively utilized in high-temperature services because of their good strength and corrosion resistance. They are made of Grade 304H stainless steel with high carbon content for a more durable product. They are available in different shapes such as fully threaded, double-ended, and tap-end to meet different industrial applications. The material makeup of 304H stainless steel guarantees higher mechanical properties to make these stud bolts suitable for pressure vessels, heat exchangers, and power plants.
Stainless Steel 304H Stud Bolts consist of carbon (0.04-0.10%), chromium (18-20%), nickel (8-11%), manganese (≤2%), silicon (≤1%), phosphorus (≤0.045%), and sulfur (≤0.03%), which adds to the strength and resistance against corrosion. Their physical properties are tensile strength of ≥515 MPa, yield strength of ≥205 MPa, elongation of ≥40%, and hardness of ≤217 Brinell (HB). The physical characteristics have a density of 8.0 g/cm³, melting point of 1400-1450°C, thermal conductivity of 16.2 W/m·K, and electrical resistivity of 720 nΩ·m, making them suitable for high-temperature applications.
