The heat treatment process of heating steel to a temperature slightly below Ac1, maintaining it for a certain period of time, and then slowly cooling is called low temperature annealing.
The heat treatment process of heating steel to a temperature slightly below Ac1, maintaining it for a certain period of time, and then slowly cooling is called low temperature annealing.Since there is no recrystalline process, the low-temperature annealing of the annealing furnace cannot refine the grain and tissue of the steel, but it can eliminate or reduce the internal stress in the steel and reduce the hardness, thereby improving the cutting performance.Low-temperature annealing has short heating time, low cost, and less loss of oxidation and decarbonization on the steel surface. In some cases, it can replace complete annealing or incomplete annealing.
