Stainless Steel 348H Flanges are made from a high-alloy austenitic stainless steel, primarily consisting of iron, chromium, nickel, along with trace amounts of niobium and carbon. This unique composition grants them remarkable mechanical properties, such as high tensile and yield strength, exceptional creep resistance, and outstanding toughness at elevated temperatures. These flanges maintain their shape under thermal stress and resist oxidation and corrosion, even in harsh environments. Their ability to endure prolonged exposure to high temperatures without compromising structural integrity makes Stainless Steel 348H Flanges perfect for critical piping systems in power plants and other high-temperature industrial applications.

348H stainless steel flanges find extensive usage in high temperature processes where corrosion and structural strength are demanded. They find extensive usage in chemical processing, petrochemicals, power generation and oil refining industries. Flanges are best suited for usage in heat exchangers, reactors, pressure vessels and steam systems where they are subjected to high temperature and corrosive chemicals. They can be hot formed or cold formed to produce flanges that match any requirement. The presence of titanium prevents carbide precipitation, thus these flanges are appropriate for welded structures. Their superior oxidation and intergranular corrosion resistance guarantees long-term performance in aggressive environments guaranteeing reliability in high-stakes pipeline systems
