Incoloy 800 Alloy: High-Performance Nickel-Iron-Chromium Alloy For High-Temperature Applications

Incoloy 800 Alloy Product Description:

Incoloy 800 is a widely used nickel-iron-chromium alloy characterized by its excellent strength and high temperature resistance. It offers exceptional resistance to oxidation, carburization, and sulfidation at elevated temperatures. The alloy maintains a stable structure during prolonged exposure to high temperatures, making it ideal for applications in industrial furnaces, petrochemical processing, and power generation.

Key Features:

• High Temperature Resistance: With a melting point of 1357-1385°C (2475-2525°F), Incoloy 800 exhibits superior strength and stability at elevated temperatures.
• Oxidation and Corrosion Resistance: Provides excellent resistance to oxidation, carburization, and sulfidation in high-temperature environments, ensuring prolonged service life.
• Mechanical Properties: Offers high tensile strength (minimum 520 MPa) and good creep rupture strength, maintaining structural integrity under stress.
• Chemical Composition: Primarily composed of nickel (30-35%), iron (39.5% min), and chromium (19-23%), with additions of copper, manganese, carbon, and silicon for enhanced properties.
• Applications: Widely used in industrial heating systems, heat-treating equipment, chemical processing plants, and thermal processing units where reliability under extreme conditions is critical.
