Conclusions 1. We determined the conditions for decarburization-free heating of carbon steels 45, U8A, U10A, and U12A in an exothermal protective atmosphere of the PSO-09 type at 800–1000o with holding for 1–20 h. To prevent decarburizing, the protective atmosphere must be dried to a greater extent than is ordinarily achieved in commercial furnaces. 2. The process of decarburizing in dry exothermal atmospheres depends on the diffusion rate of carbon from the metal to the gas—metal interface. 3. The parameters of decarburizing in relation to the humidity of an exothermal protective atmosphere can be determined by calculation with an accuracy sufficient for engineering purposes. This makes it possible to determine the optimal degree of drying of the protective atmosphere for heat treatment of steels.
