Incoloy 800

Incoloy 800 alloy typically contains 15-25% chromium, 30-45% nickel, and small amounts of aluminum and titanium. After rapid cooling from high temperatures, Incoloy 800 alloy remains in the austenitic single-phase region; therefore, its state is a single austenitic structure. The alloy has a high chromium content and sufficient nickel content, resulting in high high-temperature corrosion resistance, leading to widespread industrial applications. In chloride, low-concentration NaOH aqueous solutions, and high-temperature, high-pressure water, it exhibits excellent resistance to stress corrosion cracking, making it suitable for manufacturing equipment resistant to stress corrosion cracking.
