825

Incoloy 825 is a nickel-base alloy generally similar to Alloy 20 in aqueous corrosion. It has useful resistance to boiling sulfuric acid up to 40% concentration, to 60% concentration at 176°F and in all concentrations to 150°F. Alloy 825 is stabilized annealed at the mill to resist intergranular corrosion as-welded. If exposed for long time to the sensitive temperature range 1200-1400°F the alloy may exhibit severe intergranular corrosion in certain very aggressive environments.
