Abstract
The present work has studied the effect of subjecting an AISI 441 ferritic stainless steel in a box furnace exposure in air at 800 °C for up to 10 years. During operation, the mass gain was repeatedly measured at selected time intervals. The results show that there are only small differences in spinel composition when a sample exposed for ~5 years is compared to a sample exposed for 10 years, with the main difference being a growth of the chromia scale from ~10 to ~14 µm. In addition, the chromium content is 12.3 wt-% after 5 years whereafter it is further reduced to 10.5 wt-% during the following exposure time. Despite a relatively low chromium content already after 5 years, there are no visible signs of material failure, e.g, neither spallation nor a a large increase in mass gain during the 10 years in the furnace.
