What is the difference between high-frequency quenching and normalizing, tempering, and heating annealing? 1. Process technology is different: Normalizing is the heating of the product workpiece to Ac3 (Ac refers to the final temperature at...

1. Complete annealing Complete annealing is used to refine the coarse superheated structure of medium and low carbon steel which has poor mechanical properties after casting, forging and welding. The workpiece is heated to a temperature of 3...

Steel annealing and tempering have the same purpose and have different effects. The key use of annealing is to soften the metal material and enhance the flexibility. The application field is heat treatment of various metals. The tempering is...
