Characteristics

HP1 is an unalloyed CR-Mo-V steel with a reduced content of Mo (in comparison with TQ1) with the admixture of Nb for the refinement of structure. It excels in a comparable thermal resistance and toughness as material TQ1 while the reduced content of Mo influences the price of material at the same time. HP 1 is only produced by technology ESU, due to this the material has a high cleanness and a low content of trace elements. It is delivered in the soft-annealed state of max. 230 HB.

Suitability

HP 1 is appropriate for using in the following applications during a very high stress: pressure casting, extrusion, stamping, hot mechanical working. It is not appropriate for polished parts in comparison with material TQ 1.

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
