I often hear friends asking whether heat treatment is quenching. First of all, everyone must be clear that heat treatment includes quenching, normalizing, tempering and annealing, not just quenching.
Let us understand what heat treatment is:
Heat treatment refers to a metal thermal processing technology in which the material is in a solid state, through heating, heat preservation and cooling, to obtain the expected structure and performance.
Next, let's look at what quenching is:
Quenching is a heat treatment process in which the steel is austenitized and cooled at an appropriate cooling rate to cause the workpiece to undergo martensite and other unstable structural transformations in the cross section or within a certain range.
Now everyone understands what quenching is and what heat treatment process is.
