    • [News] Differences and effects of annealing, normalizing, quenching and tempering 日期:19-10-22 点击:163 好评:0

      The overall heat treatment is a metal heat treatment process that heats the workpiece as a whole and then cools it at an appropriate speed to change its overall mechanical properties. Annealing, normalizing, quenching and tempering are the four basic processes in the overall heat treatment. They are called “four fires”. The quenching and tempering are closely related and often used together....
