Hudson Flanges is the leading manufacturer of high quality SS 348H flange in the Midlands, UK. Made of austenitic stainless steel alloys with increased carbon content these flanges provide excellent resistance to oxidation and intergranular corrosion. Especially at high temperatures Stainless steel 348H flanges are ideal for heating high-quality applications in industries such as synthetic chemicals, petrochemicals and energy generation . They provide exceptional strength, durability and weldability ensuring reliable performance in harsh environments. At Hudson Flange we are committed to delivering perfectly designed products that meet the highest industry standards of quality and performance.
SS 348H flanges are made with 18-20% chromium, 8-10% nickel, and higher carbon content compared to standard 348. When carbide precipitation is prevented with titanium these materials increase intergranular corrosion resistance, especially in at elevated temperatures. Mechanical characteristics include tensile strength of 75-85 ksi (515-585 MPa) and good resistance to creep and oxidation under high temperature conditions. Advantages of stainless steel 348H flanges include exceptional strength, corrosion resistance against its good weldability and for chemical processing, petrochemical, power generation industries Ideal for high temperature applications check see it as a long-term, reliable project
