The scale resistance of the deposited steel 15N8G6M3FTB subjected to surface oxidation at a temperature of 900 °C was studied. It was established that the main increase in the mass of scale for this steel occurs in the first hours, and later this dependence is almost straightforward. The average weight gain of the metal scale of such a coating at 900 °C is 0.0128 kg/(m 2 ·h). It has been shown that the basis of metal oxide of composition 15N8G6M3FTB is hematite Fe 2 O 3 and magnetite Fe 3 O 4 , as well as MnO, which have weak protective properties. The number of other phase compounds with high protective properties is extremely small. The coating of steel 15N8G6M3FTB can be used for applying to the surface of parts operating at low temperatures.
