The effect of carbon content on the hardness of powder steel PK70D3 after quenching is studied. Thermokinetic diagrams are plotted for powder steels with carbon content of 0.3, 0.5, and 0.7%. The data of the thermokinetic diagrams and the method of mathematical simulation are used to compute the hardenability of powder steels PK50D3 and PK70D3.
