  • The 5% chromium content makes this steel especially desirable for punches and dies to be used in long production runs since it gives the tools far longer life
  • High wear resistance is also ideal for punches and dies to stamp silicon, stainless steels, monel metal and other types of abrasive material
  • Maintains close dimensional accuracy throughout the heat treating process, the wide 75 deg hardening range make this virtually foolproof
  • Full length identification eliminates confusion with other steels
  • Up to 50% more pieces per sharpening can be produced than with oil hardening steel
