DIN 1.2210

Tool, alloy steel

DIN 1.2210 is an alloyed tool steel containing chromium and tungsten. It is known for its very good dimensional stability during heat treatment and high hardness. It is suitable for the production of smaller tools and components where a combination of strength, hardness and wear resistance is required.


Alternative designation : 115CrW4, ČSN 19421

Type : Alloy, tool steel

Heat treatment:

  • Preheat: 600–700 °C

  • Quenching: 770–810 °C (oil)

  • Tempering: 150–250 °C (to achieve the required hardness)

Round bars, rolled, ground h9, annealed

Features:

  • High hardness (up to 64 HRC) after hardening

  • Very good dimensional stability during hardening

  • Good wear resistance

  • Lower toughness – suitable for precision tools, not for impact stress

  • Good machinability in the annealed condition

Use:

  • Drills, reamers, cold cutting tools.

  • Ejectors, pins, dies
