We craft our Incoloy 800H plate from a high-performance alloy of 30-35% nickel, 19-23% chromium, iron, with controlled carbon (0.05-0.10%), and aluminum/titanium additions for enhanced durability. The nickel and chromium form a stable oxide layer that fights oxidation and carburization up to 1500°F (816°C), while the controlled carbon boosts creep resistance for long-term performance under thermal stress. Available in thicknesses from 0.1875″ (4.8mm) to 2.00″ (50.8mm), it’s designed for easy forming and welding, meeting standards like ASTM B409 and ASME SB 409. Our rigorous testing ensures purity and consistency, delivering plates that resist scaling, creep, and thermal fatigue, lasting 3-5 years in demanding industrial environments. This makes it perfect for petrochemical, power generation, and industrial furnace applications.
