Steel 1.1730




1.1730 / C45U / C45W / AISI 1045


Properties and application:

  • steel for cold work without alloy with 675 N / mm² (max 207 HB);

  • very easy to machine;

  • good dimensional stability;

  • molds, base plates, spacer strips, simple machine parts;

  • mold making, template construction.



Material 1.1730 (C 45) is the most commonly used non-alloy tool steel. For non-alloy steels, the C content (0.45% carbon) is decisive. The working temperature is a maximum of 200 ° C.


Steel is used due to its good price-performance ratio for less thick parts and body tools. Due to the difference in the price of alloy tool steels, one must carefully check whether an alloy steel is sufficient for the application or whether an alloy steel should be used better.



We supply the steel in flat and round!

Hardening is possible but not recommended. To prevent cracking during welding, it is essential to preheat it.


For welding applications we recommend structural steel 1.0570 (ST52-3).
