Characteristics
Chrome-molybdenum steel for hardening in oil with very good hardenability and good firmness during the heat. The steel has the increased resistance to the corrosion regarding an increased content of chrome. The steel has the excellent resistance to the wear, good workability and polishability, for the usage it is delivered in the heat-treated state.
Suitability
Molds for pressing of chemically-aggressive plastic substances etc.

Heat treatment of steel W.Nr. 1.2316
| Way | Temperature [°C] | Procedure | |
|---|---|---|---|
| Forging | 850-1050 | Cool slowly in dry ash or thick cross-sections in the furnace | |
| Soft annealing | 760-800 | Warm few hours (according to the size of object), mostly four hours are enough and cool slowly in the furnace | |
| Hardening | 1020-1050 | Cool in oil or hot bath which has the temperature of 500-600°C, the degree of tempering is set by hardness and toughness of instrument according to the tempering chart | |

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
