Thanks to advanced production techniques and rigorous quality control, MERIH STAINLESS guarantees that each flange adheres to international standards for precision, durability, and performance. These Stainless Steel 348H flanges are designed to endure tough environments, providing outstanding dimensional stability and resistance to high-temperature oxidation and scaling. They come in a range of sizes and specifications, making them a popular choice in power generation, chemical, petrochemical, and industrial sectors.
Stainless Steel 348H flanges are austenitic stainless steel products primarily made of iron, chromium, nickel, and stabilized with titanium. This unique composition offers remarkable corrosion resistance, high-temperature strength, and oxidation resistance. The alloy maintains its mechanical integrity and dimensional stability even when exposed to high temperatures for extended periods, making these flanges perfect for critical applications like heat exchangers, pressure vessels, and boiler systems. The titanium stabilization helps reduce carbide precipitation, ensuring reliable performance in harsh environments.
