Heat treatment of steel W. Nr. 1.2085

WayTemperature [°C]Procedure
Forging800-1100Cool slowly in calm air or better e.g. in dry ash or other thermally-insulated material
Normalization790-810Cool in air
Soft annealing850-880Warm few hours (according to the size of object), mostly four hours are enough and cool slowly in the furnace
Annealing to lower tension600-650Warm 1 to 2 hours and cool slowly in the furnace
Hardening1000-1050Cool in oil or hot bath, the degree of tempering is set by hardness and toughness of instrument according to the tempering chart
Tempering100-500

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
