The effect of additional elements in low-alloy steel on the protective rust layer has been discussed from the view point of atmospheric corrosion. The rust layer of corrosion resistant low-alloy steel is ready up of two layers, the outer one which is α or γ FeOOH and the inner one which is amorphous or very fine spinel type oxide (Fe_3O_4). The inner layer is supposed to play an important role in the corrosion resistance of low-alloy steels in atmosphere. The method of detecting the above-mentioned dense amorphous oxide layer is presented, and the mechanism of its formation is also discussed.
