The aim of this research work was the heat treatment optimization of a high chrome white cast iron in order to obtain a final product with a high hardness (wear resistance). The effect of modifying the maintenance temperature during the different phases of the heat treatment (simple and double temperings and quenching followed by one or two temperings) on the microstructure and hardness of this product was evaluated. The necessity of performing the whole heat treatment, a quenching and a double tempering, was demonstrated in order to obtain the optimal properties of the product.
