Incoloy® 800 is an iron-nickel-chromium alloy designed for excellent strength and oxidation resistance at elevated temperatures, particularly in applications up to 1100°F (600°C). With its balanced composition, it provides superior resistance to carburization, sulfidation, and oxidation, making it ideal for high-temperature industrial environments. A key attribute of Incoloy® 800 is its ability to maintain structural stability and mechanical properties during prolonged exposure to heat, which makes it widely used across multiple industries. In petrochemical and chemical processing, it is applied in heat exchangers, process piping, and reactors that handle corrosive fluids and gases. Power generation plants utilize Incoloy® 800 in superheater tubes, steam piping, and boiler components where thermal and corrosion resistance are critical. The alloy is also common in industrial furnaces, heat-treating equipment, and nuclear power systems due to its reliability under sustained thermal stress. Fasteners made from Incoloy® 800—including bolts, nuts, screws, washers, and studs—are essential for securing assemblies in these demanding conditions. These fasteners resist oxidation, creep, and stress-corrosion cracking, ensuring long-term performance in high-heat and corrosive environments. By combining high-temperature strength with excellent corrosion resistance, Incoloy® 800 fasteners and components play a vital role in maintaining the integrity of critical equipment across heavy industrial sectors.
Incoloy® 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium, designed for excellent corrosion resistance in a wide range of aggressive environments. Its balanced chemistry provides outstanding protection against both oxidizing and reducing agents, as well as resistance to stress-corrosion cracking, pitting, and crevice corrosion. A defining property of Incoloy® 825 is its ability to withstand sulfuric and phosphoric acids, as well as chloride-containing environments, making it highly versatile for chemical and marine applications. Industries that rely on Incoloy® 825 include chemical processing, oil and gas, marine, pollution control, and nuclear power. In chemical plants, it is commonly used in heat exchangers, tanks, pickling equipment, and piping systems exposed to strong acids.
