W. NR. 1.2343
Chrome–molybdenum–silicon–vanadium 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 suitable 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.
For molds for firm and movable core parts and other parts of molds for pressure casting of aluminum alloys and large series of castings of zinc and magnesium alloys. Tools for hot mechanical working, i.e. very stressed small and middle-sized dies and inserts of dies. Dies, thorns, jaws and punches especially with the high firmness over 1800 N/mm2 cooled by water. Very stressed extruders and other auxiliary tools for extrusion of non-ferrous metals during the heat, extrusion dies for aluminum and its alloys. Tools for hot cutting, e.g. small or middle-sized shear blades, trimming dies and cutting thorns.
