Weston Stainless, Midland, UK, is a reliable provider of quality stainless steel products that meet various industrial requirements. Their Stainless Steel 347/347H Sheet and Plates are produced using columbium-stabilized austenitic stainless steel that provides good resistance to intergranular corrosion and oxidation at high temperatures. These sheets and plates are available in ASTM A240 and ASME SA240 grades, and various thicknesses and sizes to fit specific uses. SS 347 is suitable for general high-temperature use, whereas SS 347H, with increased carbon content, offers greater creep strength and resistance, making them appropriate for harsh industrial conditions.
Stainless Steel 347/347H Sheet and Plates have 17-19% chromium, 9-13% nickel, and columbium (niobium), which enhances carbide precipitation resistance. The mechanical properties are tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 40%. The hardness is approximately 95 HRB. Their physical properties include a density of 7.9 g/cm³, melting point of 1400°C, and thermal conductivity of 16.3 W/m-K. These properties provide superior strength, oxidation resistance, and thermal stability at high temperatures.
