Bohler-Uddeholm P20 PREMIUM MODIFIED Pre-hardened Mold Steel
Categories: Metal; Ferrous Metal; Alloy Steel; Chrome-moly Steel; Tool Steel; Mold Steel

Material Notes: Cr-Mo alloyed steel

P20 Modified offers the following benefits:

  • No hardening risks
  • No hardening costs
  • Time saving, e.g. no waiting for heat treatment
  • Lower tool cost (e.g. no distortion to rectify)
  • Modifications easily carried out
  • Can be subsequently nitrided to increase surface wear resistance or locally flame hardened to reduce surface damage.
      Manufactured to consistently high quality standards, P20 modified has good polishing and texturing properties, good machinability and uniformed hardness.
      Heavier sections are supplied premachined which offers the following advantages compared with unmachined material:
      • Saving of weight
      • Non-decarburized surface
      • Exact nominal size (plus tolerance)
      • Less machining
      • Absence of scale minimizes machine and tool wear
      • For large injection and compression molds
      • Extrusion dies for thermoplastics
      • Blow mold
      • High strength holders, plates and bolsters
      • Forming tools, press-brake dies (possibly flame hardened or nitrided)
      • Aluminum die casting prototype dies
      • Zinc die casting dies
      • Long run die shoes
      • Structural components, shafts.
