Our commitment is to deliver not just a product, but a solution that ensures the integrity and longevity of your piping systems, backed by our expertise and a dedication to quality that our customers have relied on for years.
The strength of Stainless Steel 348H Flanges lies in their specific composition, which includes Columbium and Tantalum for exceptional stability. This grade is designed to retain its strength and resist corrosion under high temperatures, making it far superior to standard stainless steels in challenging conditions. This robust combination of elements ensures the flanges can handle significant pressure and heat without compromising their structural integrity, providing a reliable seal when it matters most.

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
