Product Description

Overview:

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.
Characteristics:
* 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
* 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°
Application:

* Sulphuric acid piping and vessels
* Phosphoric acid evaporators
* Pickling tank heaters, pickling tanks and equipment
* Chemical process equipment
* Propellor shafts
* Tank trucks
* Calorifiers
* Electrostatic precipitator electrodes
* Hot vessels for food, water and seawater,
* Ammonium sulphate vessels
* Expansion bellows
* Marine exhaust systems
* Power station ash hoppers
