Abstract
1. Heating of the steels investigated in a fluidized bed at a temperature of 850° and holding 30 min induces negligible oxidation of the metal with an air input factor of 0.3–0.7. 2. Steel 70SKhM isothermally hardened in a fluidized bed can be recommended for the production of farm machinery blades with higher quality than those made at the present time.
