Incoloy 800HT Plate: Superior Heat Resistance for Power Generation Systems
Our Incoloy 800H T plate is engineered to deliver top-tier heat resistance, keeping power generation systems like steam generators and turbines running strong in extreme conditions. This isn’t just metal—it’s a high-performance solution for the toughest high-temperature challenges. Let’s dive into what makes our Incoloy 800HT plate a standout, from its robust materials to its critical applications, while exploring industry trends and why our company is the go-to for power generation durability.
We craft our Incoloy 800HT plate from a high-performance alloy of 30-35% nickel, 19-23% chromium, iron, with a higher carbon content (0.06-0.10%) and increased aluminum and titanium for enhanced creep strength. The nickel and chromium form a stable oxide layer that fights oxidation and carburization up to 1500°F (816°C), while the elevated carbon and Al/Ti additions boost creep and rupture strength 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 power generation environments. This makes it perfect for nuclear, fossil fuel, and renewable energy systems.
