Description |
This steel for hardening in the airflow with the high hardenability. The steel is characterized by a relatively high hardness after hardening, especially good toughness against the stress by pressure of shocks and hits, very good resistance to the wear and rather good dimensional stability at the heat treatment. It is rather difficult to form the steel at the heat and it shows relatively more difficult workability in the soft-annealed state |
