UNS N08825 Incoloy 825 is a nickel-iron-chromium alloy that contains small amounts of titanium, copper, and molybdenum. Incoloy 825’s chemical composition provides great resistance to many corrosive environments, such as pitting, crevice corrosion, intergranular corrosion, and stress- corrosion cracking. Incoloy 825 nickel alloy has good mechanical properties from moderate to high temperatures, with a hot- working range of 1600 to 2150º F. Alloy 825 also maintains good weldability for all conventional processes.
At HYT, we are an industry-leading provider of exceptional quality Incoloy 825 products including Incoloy 825 pipe, Incoloy 825 tube/tubing and Incoloy 825 plate.

UNS N08825 is designed to provide exceptional resistance to many corrosive environments. It is like alloy 800 but has improved resistance to aqueous corrosion. It also maintains excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Some of the additional benefits associated with Alloy 825, include:
Good mechanical properties at both room and elevated temperatures up to approximately 1000°F
Permission for pressure-vessel use at wall temperatures up to 800°F
Excellent resistance to reducing and oxidizing acids
Good resistance to stress-corrosion cracking
Satisfactory resistance to localized attack like pitting and crevice corrosion
Very resistant to sulfuric and phosphoric acids
