Alloy 825 features a high level of corrosion resistance. It resists general corrosion, pitting, crevice corrosion, intergranular corrosion, and stress-corrosion cracking in each reducing and oxidizing environments.
Excellent resistance to reducing and oxidizing acids
Good resistance to stress-corrosion cracking
Satisfactory resistance to localized attack like indentation and crevice corrosion
Very proof against chemical element and phosphorous acids
Good mechanical properties at each area and elevated temperatures up to some 1000°F
Permission for pressure-vessel use at wall temperatures up to 800°F
