Incoloy 800H Plate: High-Temperature Strength for Steam Generators and Furnaces
Our Incoloy 800H plate is built to deliver rock-solid strength for steam generators and furnaces, keeping critical components like tubing and superheaters reliable in scorching high-temperature environments. This isn’t just metal—it’s a tough, precision-crafted solution for power plants and industrial furnaces facing extreme heat and stress. Let’s dive into what makes our Incoloy 800H plate a top choice, from its durable materials to its key applications, while exploring industry trends and why our company is the go-to for high-temperature reliability.
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 strength. The nickel and chromium combo creates 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 steam generator and furnace environments. This makes it perfect for power generation, petrochemical, and industrial furnace applications.
