Resistant to the corrosion, Martensite steel with the high content of chrome. The steel has good resistance to the wear, good workability and polishability.
Molds for pressing of chemically-aggressive plastic substances etc.
|Steel grade||Chemical composition in %||Hardness in state|
|C||Mn||Si||Cr||W||Mo||V||Ni max||Co||P max.||S max.||HB max.||HRC min.|
|Forging||1000-1050||Cool slowly in calm air or better e.g. in dry ash or other thermally-insulated material|
|Normalization||790-810||Cool in air|
|Soft annealing||750-800||Warm few hours (according to the size of object), mostly four hours are enough and cool slowly in the furnace|
|Annealing to lower tension||600-650||Warm 1 to 2 hours and cool slowly in the furnace|
|Hardening||1000-1050||diagram Cool in oil or hot bath, the degree of tempering is set by hardness and toughness of instrument according to the tempering chart|
|Tempering||150-300||For cold work|
|400-600||For hot work|
Chart of tempering values depending on the hardness:
We will deliver any semi-finished products from the above mentioned dimensions. Other dimensions, except for given stock supplies, have to be consulted with us.
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
