Ensinger PEI
International Mold Steel PX5 Pre-Hardened Mold Steel (P20 Type)
Categories: Metal; Ferrous Metal; Tool Steel; Mold Steel

Material Notes: PX5 is a modified P20, high performance, high precision, mold steel.

Unique Characteristics:

  • Exceptionally clean steel with uniform microstructure – no pin holes, inclusions or hard spots.
  • 30-33 HRc hardness.
  • Uniform hardness throughout, even in heavy sections.
  • 75% tougher than typical chrome-moly steels.
  • Patented chemistry suppresses weld cracking and hardness elevation in the heat affected zone, eliminating the need for pre-heating and post-heating in most welding situations.
  • Machines 30-50% faster than any other P20-type steel.
  • Never needs stress relieving, even after heavy machining.

Applications:
  • plastic molds
  • rubber molds
  • press platens
  • dies
