Incoloy

BMI’s INCOLOY® Nickel–Iron–Chromium Alloys are designed for superior strength and resistance to oxidation, carburization, and sulfidation at elevated temperatures.

Compared to INCONEL, INCOLOY alloys contain a higher percentage of iron and are optimized for intermediate temperature ranges (up to ~1100°C) where both economy and performance are important.

Ideal for chemical processing, heat exchangers, petrochemical heaters, and power generation applications.

SPECIFICATIONS FOR EVERY REQUIREMENT.

GRADES

INCOLOY 800 (UNS N08800) – Excellent high-temperature strength and oxidation resistance.
INCOLOY 800H (UNS N08810) – Improved creep resistance through higher carbon content.
INCOLOY 800HT (UNS N08811) – Highest creep and rupture strength, ideal for thermal processing.
INCOLOY 825 (UNS N08825) – Corrosion-resistant grade with Mo, Cu, and Ti for reducing and oxidizing acids.

Specialty grades available upon request.
