Features and Application

  • The steel has a wide heat treatment temperature range. Basically no quenching cracking phenomenon. According to the conditions of the mold, the heat treatment process can be adjusted appropriately.
  • For cold work molds, tempered at 520~560℃ can be selected
  • For hot work molds, tempering at 600~650℃ can be selected.

This steel can be used to manufacture hot extrusion bearing ring punch, hot extrusion die, hot stamping die, precision forging die. In addition, it can also be used as cold extrusion die, cold heading die.

The hot working process of this steel is difficult to master. The tendency of forging cracking is more serious. Attention should be paid to the hot working.
