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.

Tool steel meets the requirements of various kinds of tools, e.g. for machining, hot- and cold-working, measuring instruments and die-casting moulds. We also offer high-speed steel.
Tool steel meets the requirements of various kinds of tools, e.g. for machining, hot- and cold-working, measuring instruments and die-casting moulds. These tool materials conform to great quality demands of steel, like temper, strength, toughness, resistance to tempering, hardening capacity, dimensional stability, etc. The range of tool steel in our store includes products from renowned manufacturers. We also supply high - speed steel.
Special tool steel is suitable for the manufacture of moulds, dies and pressing tools. This steel have better end-use properties than common classic steel, therefore it can help saving considerable amounts of money in manufacture.
This patented Swedish steel is distinguished by its high range of use. It is suitable for the manufacture of tools and moulds as well as machinery parts. This material can replace many kinds of classic tool and structural steel.
We supply these grades of steel: St52.3, C45, 16MnCr5, 42CrMo4
