Weston Stainless, a Midland, UK-based company, is a prominent distributor of high-quality stainless steel products that offer long-lasting and reliable solutions for industrial use. Their Stainless Steel 347 Bolts are manufactured from columbium-stabilized austenitic stainless steel, providing superior resistance to intergranular corrosion, oxidation, and high-temperature conditions. The bolts come in different shapes, such as hex bolts, U-bolts, eye bolts, T-bolts, and flange bolts, to provide secure fastening in challenging applications. With higher mechanical strength, weldability, and resistance to carbide precipitation, SS 347 bolts are best suited for applications in high–performance and long-lasting industries.
Stainless Steel 347 Bolts have 17-19% chromium, 9-13% nickel, and columbium (niobium), which improves their stability against carbide precipitation and high-temperature oxidation. The tensile strength of these bolts is 515 MPa, yield strength is 205 MPa, and elongation is 40%. Their hardness is around 95 HRB. Their physical properties are a density of 7.9 g/cm³, a melting point of 1400°C, and a thermal conductivity of 16.3 W/m-K, which makes them extremely durable and resistant to extreme heat and corrosive conditions.
