With the carburizing process, we can make use of low carbon materials that, in the course of the process, will create a high tensile strength surface with a tough core. The benefit of hardening is making high tensile surfaces throughout the part possible. If necessary, LEAX can prevent certain areas of a specific part from being carburized by applying a special paste, which is quite common in threads with small diameters. After the tempering is performed, the parts get totally hard, from surface to core. Usually, the hardness is lower than in carburized parts, ap. 40-50 HRC.
Of course, LEAX provides follow-up operations after the heat treatment, such as straightening, blasting, crack detection, hard turning, and grinding.
