W. NR. 1.2358


Chrome-molybdenum-vanadium steel is characterized by high toughness and good resistance to the wear. Further the steel has good hardenability and good dimensional stability after hardening and tempering. The steel can also be well welded and well polished. The toughness of quality 1.2358 reaches higher values than by other steels for cold work (1.2842, 1.2363, 1.2080, 1.2379, 1.2436). An excellent combination of toughness and resistance to the wear enables the usage of quality 1.2358 also for different pressing and injection applications during plastics processing.


Steel W. Nr. 1.2358 can be used both for cold work and for molds for plastics. In case of using for cold work we can talk mainly about these applications: cutting and mechanical working (also materials of bigger thicknesses), deep drawing, punching, rolling, production of shear blades, more complicated tools for cold work. In the area of molds for plastics the steel can be used e.g. for molds for large series, molds for plastics with additives, tools for plastics stamping etc.

WayTemperature [°C]Procedure
Soft annealing860Warm to 860 degrees and cool slowly in the furnace at the speed of 20 degrees an hour up to 770 degrees. Then cool at the speed of 10 degrees an hour up to 650 degrees and then cool slowly in air.
Annealing to lower tension650After rough processing warm the semi-finished product up to 650 degrees and remain at this temperature for 2 hours. Then cool slowly in the furnace up to 500 degrees and finally cool slowly in air.
Hardening950-970Pre-heat up to 600-750 degrees, austenitization temperature 950-970 degrees.
Tempering180Temper twice a minute at 180 degrees with the intercooling to the room temperature. Endurance 1hour/20 mm of thickness but at least 2 hours.

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 steelbest watch replica.

We supply these grades of steel: St52.3, C45, 16MnCr5, 42CrMo4
