It is a steel characterized by a good hardening penetration and by equally good machinability, even when hardened and, thanks to the high sulfur content.
The classic use is for molds for plastic materials, even of large dimensions, provided that the surface finish requirements are not extremely thrusts.
It is also used for plates, door molds, molds for alloys with low melting point.
