Weston Stainless, based in Midland, UK, is a renowned supplier and producer of premium-quality stainless steel products, catering to numerous industries with robust and reliable solutions. Of its high-end products, Stainless Steel 348 Pipes are most noted for its robust resistance to intergranular corrosion and stability at elevated temperatures. Manufactured in seamless, welded, ERW, and fabricated types, the pipes are produced using Grade 348 stainless steel, an austenitic columbium-stabilized alloy. Made of iron, chromium, nickel, and trace elements, these pipes provide superior oxidation resistance, high strength, and durability for severe industrial use.
Stainless Steel 348 Pipes consist of iron (balance), 17-19% chromium, 9-13% nickel, columbium for stabilization, and trace elements like manganese and silicon. They have a tensile strength of about 75 ksi (515 MPa), a yield strength of 30 ksi (205 MPa), and an elongation of 40%. Their physical characteristics are a density of 7.93 g/cm³, thermal conductivity of 16.3 W/m·K, and a melting point of about 1400°C. Such features guarantee high mechanical strength, high thermal stability, and resistance to corrosion, suitable for high-temperature conditions.
