Incoloy 800/800H/800HT Forgings mainly consist of nickel (30–35%), chromium (19–23%), and iron, with added aluminum and titanium for improved stability. The 800H grade features a higher controlled carbon content to enhance creep and rupture strength, while the 800HT variant is optimized with Al+Ti levels for exceptional high-temperature performance. These forgings boast impressive tensile strength, oxidation resistance, and structural stability for long-term use in elevated temperatures. They effectively resist carburization, chloride stress cracking, and scaling, maintaining their mechanical integrity under thermal cycling, pressure loads, and corrosive environments, making them ideal for harsh industrial settings.
