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.
