The Core Distinction: Heat vs. Corrosion To simplify the selection process, categorize the alloys by their primary strength: Incoloy 800 (UNS N08800): Engineered for High-Temperature Stability. It is the go-to choice for resistance to oxidation and carburization in heat-treating atmospheres. Incoloy 825 (UNS N08825): Engineered for Aggressive Wet Corrosion. With added molybdenum and copper, it excels in reducing acids and oxidizing chemicals where standard stainless steels fail.
