Description
Cr5Mo1V is air-quenched mold steel. This is extremely beneficial for complex molds that must retain their shape after quenching and tempering.
The deformation of this steel due to air quenching is only about 1/4 of that of manganese-containing oil-quenched tool steel. The wear resistance is between manganese type and high carbon and high chromium type tool steel. Its toughness is better than anyone. It is especially suitable for tools that require good wear resistance and special toughness. Widely used in blanking and forming dies, rolls, punches, calendering dies and rolling dies. Also used for scissors.

Heat Treatment
Annealing: 1) Slow cooling at 800-850oc 2) Spheroidizing annealing process
Tempering: 180-220oc air cooling. HRC = 60-64 510-520oc air cooling HRC = 57-60
Application
- It is used to form elastic steel sheets with a carbon content of 0.65% to 0.80%. The hardness is 37~42HRC, and the service life can reach 110,000~120,000 times. With additional nitriding treatment, the service life can reach 400,000 times.
- The steel is used for wire rolling die. For machining aluminum and copper alloys.
- It is suitable for making forming dies, blanking dies and cold blanking dies.
- It is used to make drill sleeves, punches, trimming dies and thread rolling dies.
- For wear-resistant plastic molds.
