Long-term oxidation testing in still air for two years (720 days) at 1800°F(982° C) and one year (360 days) at 2000°F (1093°C) arrd 2100°F (1149°C) has been conducted on several high temperature chromia- forming commercial alloys containing less thm 2 wt% aluminum. Alloy samples were removed from the test furnace every thirty days and the weight change that occurred due to oxide scale spallation was recorded. The importance of long-term testirrg was demonstrated with some of the alloys experiencing breakaway oxidation atler efilbitirrg low weight losses for thousands of hours. At the completion of each test the samples were examined metallographically for internal penetration (i.e. internal oxidation, voids, etc.) and compared with the weight change results. For some alloys the internal penetration was significant and the metal loss based on weight change data drastically underestimated the remaining sound metal thickness. In addition, the fraction of the average metal affected due to internal penetration was typically found to decrease with increasing temperature and those alloys with the highest concentration of Al + Si exhibited the greatest degree of internal attack. Keywords: static oxidation, internal oxidation, average internal penetration, high temperature, oxides, long-term testing

This presentation summarizes the development and expansion of a comprehensive information system for corrosion of metals and alloys in high temperature gases.  New insights in analysis of thermochemical data for the Fe-Ni-Cr-Co-C-O-S-N system are being compiled.  Corrosion mechanisms emphasized are oxidation, sulfidation, sulfidation/oxidation, and carburization.
