Advantages of Stainless Steel 348H Sheet/Plate

  1. High-Temperature Strength: Stainless Steel 348H exhibits excellent high-temperature strength, withstanding elevated temperatures up to 1700°F (927°C). This makes it ideal for applications in environments with prolonged exposure to high temperatures, such as furnace components and heat exchangers.
  2. Improved Creep Resistance: 348H offers enhanced creep resistance at elevated temperatures compared to standard austenitic stainless steels. It maintains structural integrity and dimensional stability even under long-term stress, making it suitable for applications requiring prolonged exposure to high temperatures and mechanical loading.
  3. Oxidation Resistance: Stainless Steel 348H demonstrates excellent oxidation resistance, even at high temperatures. When exposed to elevated temperatures, it forms a protective oxide layer on the surface, preventing corrosion and oxidation and ensuring long-term performance in oxidative environments.
  4. Corrosion Resistance: 348H Sheet/Plate offers corrosion resistance in many corrosive environments, including acidic and alkaline solutions. It is resistant to intergranular corrosion and stress corrosion cracking, ensuring durability and reliability in aggressive chemical environments.
  5. Versatility: Stainless Steel 348H Sheet/Plate can be easily fabricated into various shapes and components using standard machining, welding, and forming techniques. It can be tailored to meet the specific requirements of different applications, offering flexibility in design and fabrication.
  6. Low Carbon Content: The low carbon content in 348H minimizes the risk of sensitization and carbide precipitation during welding, improving its corrosion resistance in welded structures and reducing the susceptibility to intergranular corrosion.
