Cold Work Tool Steel

Cold work tool steel has a good combination of wear resistance, toughness and compressive strength. This permits heavy forming and cutting operations at room temperature.

Typical uses for Cold Work Tool Steel:

  • Blanking dies, trim dies, forming dies, coining dies, drawing dies, punches, shear blades, knives, thread-rolling dies, forming rolls, powder compaction tooling, and many other applications involving metal forming.
  • These grades may also be used in abrasive plastic processing applications.
