Pollution control Nickel Alloy Tube , UNS N08825 ASTM B163 Alloy 825 Tubing

Description:

Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum and copper. 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 1020° F

Permission for pressure-vessel use at wall temperatures up to 800°F
