Abstract

The gas simulated that used for the direct reduction of iron ores in the steelmaking process being developed in Japan. Chromel and Alumel were selectively oxidized. Chromel was also carburized at about 923 K. Severe internal oxidation occurred at about 873-1073 K in Chromel. Corrosion also affected the magnetic properties of Chromel, changing from paramagnetic to ferromagnetic. Alumel shows increasing magnetic susceptibility.
