1) | 5140 is medium carbon tempered steel, cold heading die steel; |
2) | The steel is moderate in price and easy to process. It can obtain a certain toughness, plasticity and wear resistance after proper heat treatment; |
3) | Normalizing can promote the spheroidization, improve the cutting performance of hardness less than 160HBS of blank; |
4) | The steel has the best comprehensive mechanical properties at the temperature of 550~570; |
5) | The steel is a high degree of quenching, suitable for high frequency quenching, flame hardening and other surface hardening treatment. |
