Martensitic step quenching below Ms point

Xanım nöqtəsindən aşağı olan martensitik dərəcəli söndürmə üsulu: When the bath temperature is lower than the Ms of the workpiece steel and higher than Mf, the workpiece cools faster in the bath, and the same result as the graded quenching can be obtained when the size is larger. Commonly used for larger size low hardenability steel workpieces.
