Present paper shows a simple method for obtaining hardness data required for predicting the hardness values of carburized-quenched steel parts using carburized quenching simulations. Conventionally, the relationship between cooling rate and hardness values is evaluated by preparing specimens with various carbon concentrations and performing quench tests. In new method, Jominy end-quench test with only one specimen is used to obtain carburized-quenching hardness data that reflects the effect of carbon concentration. Finally, a comparison was made between simulated results and measured values of the effective case depth after carburizing-quenching of a cylindrical steel specimen. A good agreement between experimental and simulated results was confirmed.
