1. High-temperature stability: Incoloy 800HT is designed to maintain its strength and corrosion resistance at high temperatures. It can withstand continuous exposure to temperatures up to approximately 1000°C (1832°F), as well as intermittent exposure to higher temperatures.
2. Corrosion Resistance: The Incoloy 800HT UNS N08811 has excellent resistance to oxidizing and reducing environments. It has strong corrosion resistance to acids such as sulfuric acid and phosphoric acid, as well as alkaline solutions. This makes it suitable for applications in the chemical and petrochemical industries.
3. Oxidation resistance: UNS N08811 shows excellent oxidation resistance in a high-temperature atmosphere. It forms a protective oxide layer on its surface that helps prevent further oxidation and maintains its integrity at high temperatures.
4. Creep and rupture strength: Incoloy alloy 800HT has good creep and rupture strength, which means it can withstand prolonged exposure to high stress at elevated temperatures without significant deformation or failure. This feature is critical for applications such as furnace components and heat exchangers.
5. Anti-carburization: Nickel alloy 800HT can resist carburization, that is, carbon is absorbed by metal at high temperatures. This property is valuable in applications that may be exposed to carbonaceous atmospheres.
