What's The Heat Treatment Normolizing ?

- Feb 19, 2020-

Normalizing, also known as normalization, is a metal heat treatment process in which the workpiece is heated to above Ac3 or Accm at 30-50 ° C, and after being held for a period of time, is taken out of the furnace in the air or sprayed with water, spray or air. The difference between normalizing and annealing is that the normalizing cooling rate is slightly faster than the annealing cooling rate, so the normalized structure is thinner than the annealed structure, and its mechanical properties are also improved. In addition, the cooling outside the normalizing furnace does not occupy equipment and has high productivity, so normalizing is used instead of annealing in production as much as possible.
