Hardening with high tempering

That technigue leads to an increase in the strength properties of the material (steel or spheroidal graphite cast iron) while maintaining good elongation and toughness properties. This technological process is similar to the hardening (i.e. quenching and low temperature tempering); It differs from that technology only by the tempering temperature (400 to 650 ° C compared to 150 to 400 °C) and the declared final performance requirements. Generally, high hardness is required for components in a hardened state, while for high tempered hardened components, an increased strength is required. The hardening with high tempering is carried out mainly on machine components that transmit power, torque and that are bent, and etc.; such as connecting rods, shafts, some gears, levers, safety components of road motor vehicles, and tractors, etc.
