Incoloy Alloy 825 Plate
INCOLOY® alloy 825 (UNS N08825/W.Nr. 2.4858) is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. The alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. The nickel content is sufficient for resistance to chloride-ion stress-corrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives outstanding resistance to reducing environments such as those containing sulfuric and phosphoric acids. The molybdenum also aids resistance to pitting and crevice corrosion. The alloy’s chromium content confers resistance to a variety of oxidizing substances such as nitric acid, nitrates and oxidizing salt. The titanium addition serves, with an appropriate heat treatment, to stabilize the alloy against sensitization to intergranular corrosion.
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
