Commonly used delivery states are as follows:
Quenching: The process of cooling rapidly after heating above the temperature of the phase transition point. Increase the hardness of the material, but reduce the toughness.
Normalizing: Cooling normally (in air) after heating above the phase transition temperature.
Annealing: After heating to the temperature above the phase change point, slow cooling. Eliminate quenching effect, eliminate stress, uniform composition.
Tempering: After quenching, reheating to a certain temperature (below quenching temperature), holding, and then cooling. Uniform composition, slightly reduce hardness, greatly improve toughness.
Generally speaking: first to annealing, normalizing; Eliminate the effect of original heat treatment. Then quench, then temper.
