Selection of the chemical composition of steels and their thermal hardening mode using a computer program

The relationships between the parameters of structure heat‑treated steels and their abrasive wear resistance are established. At all temperatures final tempering hardened steel, there is a direct relationship its (the number elements in solid solution, density dislocations, size cementite particles intercementite distance) when sliding friction against loose particles. A computer program has been developed to select chemical composition steel grade methods thermal hardening order ensure required resistance.
