When comparing N2 Batch HPGQ vs. Oil, whereas N2 being the most common gas quenching media used for HPGQ quenching, just begins to become as strong as oil when entering the 20-24 Bar ranges. He and H2 round out the other two gasses that both perform better than N2. Meer weergeven Quenching of steel for hardening purposes is a metallurgical process that takes place after a material is heated through its phase transformation … Meer weergeven Press quenching is a process used when batch quenching provides too much distortion where a part’s movement after quench exceeds the additional material left for post heat-treatment removal. These parts consist … Meer weergeven 4D HPGQ is a new process that allows for significant improvements to the quenching process with the main focus on reduction of distortion.
