What is the difference between Incoloy 800 and 800H?

The main difference between Incoloy 800 and Incoloy 800H lies in their composition and performance characteristics, specifically with respect to high-temperature strength and creep resistance.

Creep Strength and High-Temperature Stability:

Incoloy 800: While Incoloy 800 is a heat-resistant alloy and offers good oxidation resistance, it does not have the enhanced creep strength required for some high-temperature applications.

Incoloy 800H: Incoloy 800H is specifically designed to have improved creep strength at high temperatures (typically above 1000°F or 537°C). It is better suited for applications involving prolonged exposure to elevated temperatures, such as in high-temperature reactors or turbine components.

Nickel Content:

Incoloy 800: Contains 30-35% nickel, providing good resistance to oxidation and carburization.

Incoloy 800H: Has the same nickel content as Incoloy 800 (around 30-35%), but the difference is the higher carbon content and modified heat treatment, which enhances its stability under prolonged stress at high temperatures.

Temperature Range:

Incoloy 800: Suitable for applications up to around 1100°F (593°C), typically used in environments where the temperature doesn’t exceed the alloy’s limits for strength and corrosion resistance.

Incoloy 800H: Performs better in higher temperature environments, often used for applications requiring extended high-temperature exposure, like reactors, heat exchangers, and gas turbines operating at temperatures exceeding 1100°F (593°C).+

Heat Treatment:

Incoloy 800: Can be heat-treated to improve its strength, but it doesn’t have the same level of heat resistance as Incoloy 800H without further modifications.

Incoloy 800H: Specifically heat-treated for improved high-temperature strength and creep resistance, making it suitable for applications requiring long-term thermal stability.

Summary of Differences:

Feature	Incoloy 800	Incoloy 800H
Carbon Content	0.05% to 0.10%	Controlled carbon content up to 0.05%
Creep Strength	Moderate at high temperatures	Enhanced creep strength at high temperatures
Temperature Range	Up to 1100°F (593°C)	Better performance at higher temperatures
Applications	Furnace parts, heat exchangers, etc.	High-temperature reactors, turbines, etc.
Strength at High Temperatures	Standard high-temperature strength	Higher strength and creep resistance at high temperatures

In essence, Incoloy 800H is a more advanced version of Incoloy 800, designed specifically for high-temperature applications where long-term stability and resistance to creep are critical.
