DIN 1.2101

Tool alloy steel with higher toughness

DIN 1.2101 is an alloyed tool steel with a higher carbon, chromium and vanadium content. Compared to conventional high-carbon steels, it offers better toughness and is suitable for medium-duty tools. It allows for high hardness and good wear resistance.


Alternative designation : 62SiMnCr4, ČSN 19452

Type : Alloy tool steel

Heat treatment:

  • Preheat: 600–800 °C

  • Quenching: 800–850 °C (oil)

  • Tempering: 180–250 °C depending on the required hardness
