CORROSION PERFORMANCE OF AUSTENITIC AND FERRITIC ALLOYS IN AUTOMOBILE EXHAUST TRAIN ENVIRONMENTS
The performance of several commercial austenitic and ferritic alloys has been evaluated from 1300-2000 degrees F in cyclic air plus 10 percent water vapor and is a gasoline engine exhaust gas from 1300-1800 degrees F. The significance of underscaled and descaled weight losses, metal loss, depth of internal attack, and total depth of damage is discussed, along with visual inspection and microstructure. The austenitic alloys exhibited better behavior than the ferritic alloys, with the exception of 18 SR.
