Measures to reduce cracking of 51CrV4 steel

In order to reduce the cracking phenomenon at the end of 51CrV4 steel, it is recommended to take the following measures:
1.Control the cooling of 51CrV4 steel after rolling, take appropriate measures for slow cooling, reduce the cooling rate of 51CrV4 steel and control it within a reasonable range, and inhibit the formation of bainite structure;

2.Increase the shear temperature of 51CrV4 steel;

3.Control the cooling rate of 51CrV4 steel after shearing to prevent delayed cracking. The machine should be moved quickly to suppress stress concentration after shearing and cause aging cracking.

The above measures cannot fundamentally solve the problem of cracking at the end of 51CrV4 steel, but it can greatly reduce the occurrence of this phenomenon. If you need to purchase 51CrV4 steel or consult more details, please feel free to contact us.
