Chloride-ion stress-corrosion cracking is adequate to prevent chloride-ion stress. Molybdenum contributes to the resistance of metals to pitting and crevice corrosion. Chromium provides resistance to oxidising conditions, while titanium prevents the alloy from becoming sensitised to intergranular corrosion.

Alloy 825 exhibits excellent mechanical properties at temperatures ranging from cryogenic to moderately high temperatures near 540°C. Additionally, it has high impact strength at room temperature and retains its strength when frozen. Cold working can significantly strengthen this alloy.
