Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. It is similar to alloy 800 but has improved resistance to aqueous corrosion. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Alloy 825 is especially resistant to sulfuric and phosphoric acids. This nickel steel alloy is used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.

Feature
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
Application
Due to its superior corrosion resistance characteristics, Incoloy 825 is in use in a number of industries and applications including:
- Chemical processing components
- Oil and gas piping, recovery
- Acid production
- Pickling tank heaters, tanks, and equipment
- Marine exhaust systems
- Pollution control equipment
- Calorifiers
- Hot vessels for food, water, and seawater
- Nuclear fuel reprocessing
- Radioactive waste handling
It is an alloy that provides high levels of corrosion resistance to both moderately oxidizing and moderately reducing environments.
