ASTM N08825 Welded Stainless Steel Electric Heating Tube

N08825 is the material designation for Incoloy 825, which is a nickel-iron-chromium alloy with excellent corrosion resistance in various environments, including acidic and chloride-containing environments. Incoloy 825 welded tubes can be used in electric heaters for specific applications that require its unique properties.

Incoloy 825 welded tubes can be utilized in electric heaters for the following reasons:

1. Corrosion Resistance: Incoloy 825 offers exceptional resistance to corrosion, making it suitable for electric heaters that operate in aggressive environments. It resists corrosion from sulfuric acid, phosphoric acid, and other acidic solutions, as well as chloride-induced stress corrosion cracking.

2. High-Temperature Strength: Incoloy 825 retains its strength and integrity at elevated temperatures, making it suitable for electric heaters that require heating fluids to high temperatures.

3. Resistance to Scaling and Oxidation: Incoloy 825 exhibits good resistance to scaling and oxidation at high temperatures. This property is beneficial in electric heaters where the heating elements are exposed to air or other oxidizing environments.

4. Compatibility with Various Fluids: Incoloy 825 is compatible with a wide range of fluids, including corrosive chemicals and seawater. This makes it a suitable choice for electric heaters used in industries such as chemical processing, oil and gas, and marine applications.

When using Incoloy 825 welded tubes in electric heaters, it is important to ensure proper design, fabrication, and installation to maximize the performance and longevity of the heating system. Consulting with materials engineers or experts in electric heater design is recommended to ensure the appropriate selection and use of Incoloy 825 welded tubes for specific electric heating applications.
