High Tempreture Incoloy Alloy 825 UNSN08825 For Bar Plate Pipe Tube
Chemical Processing
Introduction
INCOLOY 825 is a nickel-iron-chromium alloy with additions of
molybdenum, copper, and titanium. The alloy’s chemical composition,
given in Table 1, 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.
The resistance of INCOLOY 825 to general and localized corrosion
under diverse conditions gives the alloy broad usefulness.
Applications include chemical processing, pollution control, oil
and gas recovery, acid production, pickling operations, nuclear
fuel reprocessing, and handling of radioactive wastes. Applications
for alloy 825 are similar to those for INCOLOY alloy 020.
