THE PRODUCTION PROCESS OF QUENCHING TEMPERING BAR

 Quenching  tempering bar mostly work under relatively large dynamic loads. They are subjected to tension, compression, bending, torsion or shear. Some surfaces also have friction, requiring a certain degree of wear resistance and so on. In short, parts work under various complex stresses. These parts are mainly structural parts of various machines and mechanisms, such as cylinder shafts, connecting rods, bolts, gears, etc. They are widely used in machine tools, automobiles, tractors and other manufacturing industries.

Especially for large parts in heavy machine manufacturing, quenching and high temperature tempering is more used. Because of the different stress conditions, the properties of conditioned parts in mechanical products are not exactly the same. Generally speaking, all kinds of quenched and tempered chrome bar should have excellent comprehensive mechanical properties, that is, proper combination of high strength and high toughness, in order to ensure the long-term smooth work of parts.Heat Treatments Of YUTONG's rod bar: Quench and Temper, Induction hardening, Surface hardening Normalizing ,Stress Relief Annealing​​
