Incoloy® 800 Rod

Incoloy® 800 Rod is a nickel–iron–chromium alloy notable for its ability to maintain structural stability and mechanical strength under prolonged high-temperature service. Its resistance to oxidation and carburization makes it a preferred material in environments where both heat and chemical attack are severe. The alloy finds primary applications in power generation, petrochemical, and heat-treatment industries, where rods are used for furnace supports, structural components, and heater assemblies. Specific uses include boiler tubes, reformer supports, and mechanical fasteners exposed to aggressive thermal cycling. In research, Incoloy® 800 Rod is employed to study long-term metallurgical stability and to develop advanced corrosion-resistant systems for energy and chemical plants. Its balance of mechanical integrity, corrosion resistance, and durability ensures lasting value in both scientific innovation and industrial reliability.
