Incoloy 825® is a nickel-iron- chromium
alloy with titanium, copper, and molybdenum. Incoloy® 825’s chemical
composition provides great resistance to many corrosive environments,
such as pitting, crevice corrosion, intergranular corrosion, and stress-
corrosion cracking. Incoloy 825® has good mechanical properties from
moderately to high temperatures. The hot- working range for Incoloy 825®
is 1600 to 2150ş F. The material has good weldability by all conventional
processes.
Available forms are seamless pipe, welded pipe,
seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe
fittings and flanges. |
