DIN 1.1730

Tool carbon steel

DIN 1.1730 is a medium carbon tool steel. It is characterized by good machinability and easy heat treatment. Due to its lower wear resistance and lower hardenability, it is used for less stressed tools, fixtures and components where high hardness or impact resistance is not required.


Alternative designation : C45W, C45, ČSN 19083

Type : Carbon tool steel

Heat treatment:

  • Hardening: approx. 820–860 °C (water or oil)

  • Tempering: approx. 550–660 °C
