Evaluation of Nickel-Alloy Panels from the 20-Year ASTM G01.04 Atmospheric Test Program Completed in 1996


This paper is an evaluation of 20-year atmospheric exposure test panels of Nickel 200 (UNS N02200), MONEL® alloy 400 (UNS N04400), INCONEL® alloy 600 (UNS N06600), INCONEL alloy 625 (UNS N06625, INCOLOY® alloy 800 (UNS N08800) and INCOLOY alloy 825 (UNS N08825) from the ASTM Committee G01.04 Atmospheric Test Program, started in the United States of America's bicentennial year of 1976 and completed in 1996. The 20-year exposure test panels were evaluated to determine corrosion rates, pit depth data, and mechanical properties. The results are reported for each alloy as average values of three individual test panels exposed at each of five test sites. The test sites are ranked as to severity.
