ASTM B163 Bright Annealed Stainless Steel Tube Incoloy 825 SS Coil Tubing OD 1/2'' X 0.035''
Alloy 825 is an austenitic nickel-iron-chromium alloy with additions of copper, molybdenum and titanium. The alloy chemical composition is designed to provide exceptional corrosion resistance in both oxidizing and reducing environments. The nickel content is sufficient for resistance to chloride-ion stress corrosion cracking and the molybdenum also aids resistance to pitting and crevice corrosion. The addition of titanium stabilized the alloy 825 against sensitization and inter granular corrosion. The resistance of alloy 825 to general and localized corrosion under diverse conditions gives the alloy broad use fullness.
INCOLOY® alloy 825 (UNS N08825/W.Nr. 2.4858) 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 alloy 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.
