W. NR. 1.2714

Characteristics

Nickel-chrome–molybdenum-vanadium steel for hardening in the stream of air or in oil with high hardenability. The steel has high hardness after hardening, good resistance to the tempering, good toughness and good firmness during the heat. Is resists quick temperature changes and also thermal fatigue. The steel is well-workable during the heat and well-workable in the soft-annealed state.

Suitability

For tools for mechanical working during the heat such as dies of all sizes, especially with the firmness over Nmm2 for drop hammers and forging presses, extruders with the firmness over 1600 Nmm2 for extrusion of non-ferrous metals. Further the steel is appropriate for knives during the cold cutting of materials of thick thicknesses, knives for scrap iron. For pressing of plastic substances, big forces and breeze-blocks can be produced from this steel and these can be hardened in air.

WayTemperature [°C]Procedure
Forging850-1100Cool slowly in air or in other thermally-insulated material
Soft annealing650-700Warm 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
Hardeningin air860-900Bigger and more rugged tools
in oil830-870Cool in oil up to about 100 °C
Tempering450-650Cool 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
