5140 steel is medium carbon modulated steel and cold heading die steel. The steel is inexpensive and easy to process. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. Normalizing can promote the spheroidization of the structure and improve the cutting performance of the blank with hardness less than 160HBS. Tempered at 550~570 ℃, the steel has the best comprehensive mechanical properties. The hardenability of this steel is higher than that of S45C steel, and it is suitable for surface hardening treatment such as high-frequency quenching and flame quenching.
