Steel properties :

High-alloy chrome steel with big hardenability for hardening in oil and in air, especially high resistance to the wear both by metal and by mineral substances, good cutting power, very high hardness in the pressure, significantly low toughness especially in traverse, significant carbide spacing. This steel has a good dimensional stability during the heat treatment but the change of dimensions is bigger than by the steel 1.2842. The steel is sensitive to the fast and uneven heating, suitable for hardening on the secondary hardness (the possibility of nitriding). Further the steel is brushed with big difficulties, at the heat it is forged with big difficulties and it has a rather difficult workability in the annealed state.
