W. NR. 1.2210

Characteristics

Chrome-vanadium steel with the middle hardenability for hardening in oil and water, relatively good toughness at the high hardness, good resistance to the wear and cutting power. More difficult ductility during the heat and good workability in the annealed state.

Suitability

Tools for cold cutting, i.e. cutting tools and punching tools, shear blades for cutting of materials of smaller thicknesses. Cutting tools for machining by smaller cutting speeds, e.g. drills, reamers, screw taps etc. Further for molds and auxiliary components, e.g. ejectors, pins etc.

Heat treatment of steel W.Nr. 1.2210

WayTemperature [°C]Procedure
Forging800-1050Cool slowly in calm air or better e.g. in dry ash or other thermally-insulated material
Soft annealing710-750Warm few hours (according to the size of object), mostly four hours are enough and cool slowly in furnace
Annealing to lower tension600-650Warm 1 to 2 hours and cool slowly in the furnace
Hardeningin water810-840Materials of thickness up to about 15 mm
in oil780-810Materials of thickness above about 15 mm
Tempering180-250Cool in air, 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 has 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
