We craft our Incoloy 800HT seamless tube 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 superior 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 diameters from 0.5″ (12.7mm) to 8″ (203.2mm) and wall thicknesses from 0.065″ (1.65mm) to 0.5″ (12.7mm), it’s designed for seamless construction and weldability, meeting standards like ASTM B407 and ASME SB 407. Our rigorous testing ensures purity and consistency, delivering tubes that resist scaling, creep, and thermal fatigue, lasting 3-5 years in demanding furnace environments. This makes it perfect for petrochemical, steel production, and power generation applications.
In industrial furnace applications, our Incoloy 800HT seamless tube is a workhorse. It’s used in radiant tubes, resisting oxidation and creep in high-heat steel and glass production. Reformer tubes in ammonia or methanol production rely on it to handle carburizing atmospheres at 1500°F (816°C). Heat exchanger tubing benefits from its ability to withstand thermal cycling and oxidation, ensuring efficient heat transfer. We’ve seen it applied in petrochemical furnaces, resisting carburization from hydrocarbon processing, and in power plants, handling high-temperature combustion byproducts. Its seamless design ensures uniform strength and corrosion resistance, while its weldability makes it ideal for fabricating complex furnace assemblies, ensuring robust performance in high-heat systems.
