Characteristics
TQ 1 is an unalloyed Cr-Mo-V steel with very high toughness, firmness during the heat and resistance to the hot abrasion (higher than by other classic steels 1.2343, 1.2344, 1.2367). TQ 1 is produced only by ESU technology due to which the material has a high cleanness and a low content of trace elements. It is delivered in the soft-annealed state of max. 220 HB.
Suitability
TQ 1 is appropriate for using in the following applications during a very high stress: pressure casting, extrusion, stamping, hot working. It is very appropriate for highly polished parts of molds (e.g. production of headlights etc.) due to ESU properties.

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
