Physical properties of Incoloy 800/800H

Tensile strength: σb≥450Mpa

Elongation: δ≥35%

The chemical composition of INCOLOY 800/800H/both are very similar, so both have good resistance to reduction, oxidation, nitriding medium corrosion and resistance to alternating redox medium corrosion performance, and high metallurgical stability in high temperature long-term applications. However, due to the different content of (Al+Ti), the two materials are used in different environments, specifically: INCOLOY 800 at sub-zero, room temperature and 600 ℃ high temperature will play a variety of properties. It is recommended to select the material according to the environment in which it is often used.
