Overview
As a leading Incoloy Alloy 800 supplier in China, AEETHER provides cost-effective Incoloy® 800 products for a variety of industrial applications.

Incoloy® 800 (UNS N08800 / W.Nr. 1.4876) is a solid-solution nickel-iron-chromium alloy known for its exceptional resistance to oxidation and carburization at elevated temperatures. It combines the high-temperature strength of austenitic alloys with excellent resistance to oxidation, sulfidation, and carburization. Incoloy 800, Incoloy 800H, and Incoloy 800HT are ideal materials for use in harsh, high-temperature environments, particularly within the chemical and petrochemical industries.

Incoloy 800 is widely used in heat exchangers, furnace components, nuclear reactors, and other applications that demand high strength and resistance to oxidation at high temperatures. It is also frequently used in thermal processing equipment, such as in the production of heat exchangers, piping, and combustion chambers.

Mechanical Properties
Incoloy Alloy 800 offers outstanding mechanical properties at high temperatures, making it suitable for applications that experience both mechanical stress and elevated temperatures. The alloy maintains good tensile strength and creep resistance up to approximately 1100°F (593°C).

At high temperatures, Incoloy 800H and Incoloy 800 exhibit excellent strength, toughness, and low thermal expansion rates. These alloys also show great resistance to thermal fatigue, making them ideal for use in demanding high-temperature environments. Incoloy 800HT is specifically designed to retain its mechanical properties even under extreme heat, ensuring long-term performance in harsh conditions.

Corrosion Resistance
Incoloy 800 is highly resistant to both oxidation and carburization, particularly in high-temperature environments. This superior corrosion resistance makes Incoloy 800 ideal for furnace and combustion applications where exposure to high heat and aggressive chemical conditions is common.

The alloy also demonstrates exceptional resistance to many forms of sulfuric acid and chloride stress cracking, offering reliable performance in high-temperature and chemically aggressive environments. Incoloy 800H is especially resistant to corrosion in both carburizing and oxidizing atmospheres, making it a popular choice in petrochemical refining processes and similar high-temperature applications.

• Oxidation Resistance: Incoloy 800 provides outstanding protection against oxidation at elevated temperatures, making it a preferred material for furnace components and high-heat environments.
• Corrosion Resistance: The alloy exhibits remarkable resistance to sulfur-containing gases and acids, particularly at high temperatures, and is also highly resistant to aqueous corrosion in a variety of chemical environments.

Density of Incoloy 800
The density of Incoloy 800 is approximately 7.94 g/cm³ (7940 kg/m³) at room temperature. This makes it a relatively dense alloy, suitable for applications where strength and durability are critical in high-temperature conditions.
