Steel 1.2842 / 90MnCrV8

1.2842 steel is a medium alloy cold work steel containing approximately 1% carbon. It has a high hardening ability towards the core. It is dimensionally stable and offers good compression strength. It has a similarity to 1.2510 steel. 1.2842 quality steel is also called oil steel because it can be hardened in oil.

DIN 1.2842 STEEL TYPICAL APPLICATIONS

  • Suitable for making various precision templates, block gauges and measuring tools with small deformation and good wear resistance
  • Suitable for making small stamping dies with thickness less than 6mm.
  • Suitable for scissors, taps, dies and reamers, etc.
  • After quenching and low temperature tempering, its hardness is ≤55HRC, which is suitable for molds with small production batches and high requirements on strength and wear resistance.
  • Higher-sized punching dies, cold pressing dies, engraving dies, and plastic dies.
  • For making thermosetting plastic molds with quenching hardness of 46~52HRC
  • Small cores, punches, cavity plates, inserts, etc.
  • For solid hardened plastic molds.
  • Suitable for making plastic molds with smaller size, more complex shape and higher precision.
  • Thermosetting plastic molding die, requiring high wear resistance and high strength
