The **Incoloy 800/800H/800HT Sheet and Plates** are primarily made up of nickel (30–35%), chromium (19–23%), and iron (the balance), with small amounts of carbon, titanium, and aluminum added in. The 800H and 800HT grades feature a higher carbon content, which boosts their strength at elevated temperatures. These sheets and plates deliver tensile strength between 550–700 MPa and yield strength ranging from 205–450 MPa, depending on the specific grade. **Incoloy** is known for its excellent resistance to oxidation, scaling, and thermal fatigue, maintaining mechanical stability at temperatures as high as 1100°C, while also offering good weldability and formability.
