Annealing and Tempering #steel #shorts

The difference between annealing and tempering: Simply put, annealing means that hardness is not required, and tempering still retains a certain hardness. Tempering is generally not used alone. Tempering is performed after the parts are quenched. The main purpose is to eliminate the quenching stress and obtain the required structure. Tempering is divided into low temperature, medium and high temperature tempering according to the tempering temperature.
