Incoloy 800H Plates/Bars/Tubes

Incoloy 800H is a nickel-iron-chromium alloy specifically designed to provide enhanced high-temperature strength and superior resistance to oxidation and carburization in extreme environments. It is a modified version of Incoloy 800, distinguished by its controlled higher carbon content (0.05-0.10%), which improves its creep and stress rupture strength at elevated temperatures above 600°C (1112°F).
