Inconel 800

Inconel 800 by Riyaarth Overseas in Mumbai

Inconel 800 is a nickel-iron-chromium alloy known for its excellent strength, oxidation resistance, and stability in extreme high-temperature environments. Designed for applications that require high-performance materials to withstand prolonged exposure to elevated temperatures and corrosive conditions, Inconel 800 is widely used across industries such as chemical processing, power generation, and petrochemical refining.

Key Features of Inconel 800

  1. High-Temperature Strength: Retains its strength and structural integrity in temperatures up to 1100°C (2010°F).
  2. Excellent Oxidation Resistance: Resists scaling and maintains surface stability in oxidizing atmospheres.
  3. Good Corrosion Resistance: Particularly effective against sulfuric and nitric acids, making it suitable for chemical processing environments.
  4. Resistance to Carburization: Ideal for applications exposed to carbon-rich gases at high temperatures.
  5. Structural Stability: Maintains excellent creep and rupture strength over extended periods.

Applications of Inconel 800

  1. Chemical and Petrochemical Processing: Ideal for heat exchangers, process piping, and reactors due to its resistance to corrosion and oxidation.
  2. Power Generation: Commonly used in superheaters and reheaters in power plants.
  3. Industrial Furnaces: Used in furnace components, radiant tubes, and supports due to its high-temperature stability.
  4. Heat Treatment Equipment: Essential for trays, baskets, and fixtures used in heat-treating furnaces.
  5. Nuclear Industry: Preferred for steam generator tubing and other components in nuclear power plants.
  6. Gas Turbines: Components exposed to high heat and stress in turbine engines.

Advantages of Inconel 800

  1. Extended Service Life: Withstands prolonged exposure to high temperatures and corrosive environments.
  2. High Structural Integrity: Resists deformation under mechanical stress and thermal cycling.
  3. Versatile Fabrication: Easily machined and welded, making it suitable for complex designs.
  4. Reduced Maintenance: Superior corrosion and oxidation resistance reduce the need for frequent repairs and replacements.

Available Forms

  1. Sheets and Plates: Used for structural and thermal applications.
  2. Bars and Rods: Ideal for machining and custom fabrication.
  3. Pipes and Tubes: Suitable for the transport of high-temperature or corrosive substances.
  4. Forgings: Customized shapes for specialized industrial needs.
  5. Wire and Strips: Precision materials for heating elements and fine applications.

FAQs

What is the main difference between Inconel 800 and Inconel 600?

Inconel 800 contains higher iron content compared to Inconel 600, providing superior structural stability and creep resistance at high temperatures.

Is Inconel 800 suitable for cryogenic applications?

While primarily used in high-temperature applications, Inconel 800 also performs well in cryogenic conditions due to its toughness and ductility.

Can Inconel 800 be welded?

Yes, Inconel 800 is weldable using standard welding techniques such as TIG and MIG. Preheating and post-weld heat treatment are not generally required.
