Carbon tool steel characterized by adequate hardness of hardening layer, high toughness and very significant insensitivity to hardening cracks. Further the steel is characterized by good ductility at the heat and good workability in the annealed state.
For locksmith and assembly tools, tools for woodworking, hardened components of molds, e.g. base plates, cases, columns, stops, suspension components and products etc. Further the steel is appropriate for agricultural, blacksmith and bricklayer tools.

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
