Incoloy 800 Alloy Plate (Ni-Fe-Cr Alloy)
Engineered for chemical processing, heat treatment, and nuclear applications demanding superior oxidation resistance and thermal stability, Incoloy 800 alloy plate combines a nickel-iron-chromium matrix (Ni-30%, Fe-39.5%, Cr-21%, Al-0.4%, Ti-0.4%) to deliver unmatched resistance to oxidation, carburization, and sulfur environments up to 815°C (1,500°F). Certified to AMS 5542, ASTM B409, and ASME SB409, this alloy outperforms 310S stainless steel and Inconel 600 in carburizing and oxidizing conditions, offering 2x the lifespan in cyclic thermal and acidic environments.

FAQ
Q1: How does Incoloy 800 compare to Inconel 600 in carburizing environments?
A: Incoloy 800 offers 40% lower carburization rates at 800°C due to its aluminum/titanium stabilization, while Inconel 600 excels in higher chloride resistance.
Q2: What heat treatment optimizes high-temperature performance?
A: Anneal at 1,010–1,070°C (1,850–1,958°F) for 20–30 minutes, followed by rapid air cooling to stabilize the grain structure.
