Assab Steels ASP 23 Cold Work Steel
Categories: Metal; Ferrous Metal; Chrome-moly Steel; Tool Steel; Cold Work Steel

Material Notes: ASP 23 is a chromium-molybdenum-tungsten-vanadium alloyed high speed steel which is characterized by:
  • High wear resistance (abrasive profile)
  • High compressive strength
  • Very good through-hardening properties
  • Good toughness
  • Very good dimensional stability on heat treatment
  • Very good temper resistance

ASP 23 is especially suitable for blanking and forming of thinner work materials where a mixed (abrasive-adhesive) or abrasive type of wear is encountered and where the risk for plastic deformation of the working surfaces of the tool is high, e.g.:

  • Blanking of medium to high carbon steels
  • Blanking of harder materials such as hardened or cold-rolled strip steels
  • Plastics mold tooling subjected to abrasive wear condition
  • Plastics processing parts, e.g. feed screws, barrel liners, nozzles, screw tips, non-return check ring valves, pellitizer blades, granulator knives.
