Steel properties

ALTA 1.2367 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.

This 1.2367 steel increases the content of Mo on the basis of 1.2344/H13 steel, while reducing the content of Si, in order to improve the secondary hardening effect of the material during tempering.

Its thermal stability and impact toughness were better than that of 1.2344/H13 steel.
