Characteristics
Chrome-vanadium steel with the middle hardenability for hardening in oil, good dimensional stability after the heat treatment, especially good dimensional stability after the heat treatment and artificial aging, high hardness, very good resistance to the wear and cutting power, more significant carbidic spacing, slightly difficult ductility at the heat, good workability in the annealed state.
Suitability
Steel suitable for cutting tools, profile knives and milling machines for a fine machining of coloured metals and plastics by lower cutting speeds, machine files, tools for woodworking, tools for cold cutting, circular cutting knives.

Heat treatment of steel W.Nr. 1.2063
| Way | Temperature [°C] | Procedure | |
|---|---|---|---|
| Forging | 850-1050 | Cool slowly in calm air or better e.g. in dry ash. | |
| Soft annealing | 750-780 | Několik hodin prohřát (podle velikosti předmětu), většinou stačí 4 hodiny a pomalu ochlazovat v peci. Warm few hours (according to the size of object), mostly four hours are enough and cool slowly in the furnace. | |
| Annealing to lower tension | 600-650 | Warm 1 to 2 hours and cool slowly in the furnace. | |
| Hardening in oil | 830-870 | Cool in air, the degree of tempering is set by hardness and toughness of instrument according to the tempering chart. | |
| Tempering | 150-250 | Cool in air. | |

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
