Description |
This steel for hardening in oil and in air with very good hardenability, high firmness during the heat and resistance to the tempering, very good toughness and plastic properties during normal and also higher temperatures. Further the steel has a very good resistance to tearing of thermal fatigue and low sensitivity to quick changes of temperature. The steel is appropriate for the heat treatment also for firmness over 1800 N/mm2 and for tools cooled by water. It is well-workable during the heat and well-workable in the soft-annealed state. In comparison with the steel CSN 19 552 this steel has a lowered content of Si and an increased content of Mo which in its consequence enables achieving higher firmness. At request it can also be delivered in ESU quality. |
