Abstract
The invention discloses a steel material for a cold-working mould. The steel material comprises, by weight, 0-3 % of carbon, 1-5 % of tungsten, 6-8 % of chromium, at most 5 % of silicon, at most 0.35 % of niobium, at most 0.35 % of manganese, at most 0.35 % of nickel, 10-12 % of zinc, 3-8 % of copper and the balance iron. The steel material for the cold-working mould has the beneficial effects that the steel material is mainly composed of iron, chromium, zinc and copper, so that embrittlement cracking of the mould is reduced or avoided, the production cost is reduced, the service life of the mould is prolonged, and the properties are improved.
Description
Technical field
The present invention relates to a kind of steel, particularly relate to a kind of cold-work die steel material.
Background technology
Die steel is used to the steel grade manufacturing the moulds such as cold-punching mould, hot-forging die, transfer mold.Mould is the main machining tool of finished parts in the industrial sectors such as machinofacture, radio meter, motor, electrical equipment.The quality of mould directly affects the quality of pressure processing craft, the precision output of product and production cost, and the quality of mould and work-ing life are except by except rational structure design and working accuracy, main by moulding stock with heat treatedly to affect.The die steel material of existing employing hotwork manufacturing process easily occurs the phenomenon of cracking have impact on quality in long-time use procedure.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The invention provides a kind of cold-work die steel material.
The technical solution used in the present invention is:
A kind of cold-work die steel material, the chemical composition of this steel and weight percent are:
Carbon is less than or equal to 3%;
Tungsten 1-5%;
Chromium 6-8%;
Silicon at the most 5%;
In niobium, manganese and nickel each maximum 0.35%;
Zinc 10-12%;
Copper 3-8%;
Iron is surplus.
Further, in described niobium, manganese and nickel each minimum 0.02%.
Further, the particle diameter of each chemical composition is 8-12 μm.
Further, the mass percent of described silicon is at least 1%.
The invention has the beneficial effects as follows: this kind of cold working die steel material forms minimizing by iron, chromium, zinc and copper main component or avoid mould to collapse crisp cracking, reduces production and application cost, extends the mold use life-span, improve performance.
