Influence of the Heat Treatments on the Wear-Resistant Steels Properties

Abstract

The paper presents how the final heat treatments quenching (hardening) followed by tempering influence the properties of the wearresistant steels. The quenching temperature and maintaining time at quenching temperature have influence on the studied steels hardness. The study shows that maintaining time has an optimum interval for which the maximum hardness is reached. Also the quenching temperature influences the hardness; higher values are obtained when the quenching temperature attend the maximum allowed. The resilience and wear, other essential tools properties, were studied to find the optimal heat treatment parameters to provide the highest values of mechanical characteristics.
