Abstract
The invention discloses a cold work die steel material. With 30-40 parts of iron as a raw material, the cold work die steel material comprises the following components in parts by weight: 3-5 parts of carbon, 0.5-0.8 part of silicon, 0.9-1.33 parts of molybdenum, 1.2-1.5 parts of copper, 20-25 parts of graphite, 0.66-0.78 part of sodium, 0.0068-0.045 part of chrome and 0.1-0.5 part of technetium. The cold work die steel material has the beneficial effects that the components are scientific and reasonable in proportion; inoculation on steel is carried out by high-activity sodium and silicon, so that the nucleation rate is improved; crystal grains are refined; the overall mechanical properties of the steel are effectively improved; the service life of the cold work die steel material is prolonged; and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of die steel material, particularly relate to a kind of cold working die steel material.
Background technology
Steel, at castingprocesses, crystal boundary easily occurs thick netted eutectic carbides and herring-bone form carbide, and crystal grain is thicker, and the intensity of steel and toughness are obviously reduced, serious curtailment die life.Obtaining the more tiny tissue of crystal grain and preventing thick network-like carbide to occur at crystal boundary is the prerequisite obtaining good blank tissue.In the Foundry Production of current various steel, multiple alterant is widely used and improves weave construction with crystal grain thinning.
Steel is a kind of cold-work die steel with extensive use, improves its starting material tissue, and improving its performance will have larger economic implications.Potassium sodium alterant is a kind of alterant, is widely used in casting.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The invention provides a kind of cold working die steel material.
The technical solution used in the present invention is:
A kind of cold working die steel material, with the iron of 30-40 weight part for raw material, also comprises the component of following weight part:
Carbon 3-5 part;
Silicon 0.5-0.8 part;
Molybdenum 0.9-1.33 part;
Copper 1.2-1.5 part;
Graphite 20-25 part;
Sodium 0.66-0.78 part;
Chromium 0.0068-0.045 part;
Technetium 0.1-0.5 part.
Further, the cobalt of 1-2 weight part can also be added.
Further, the aluminium of 5-10 weight part can also be added.
The invention has the beneficial effects as follows: component proportion is scientific and reasonable, adopt highly active sodium silicon to carry out inoculation to steel, improve its nucleation rate, crystal grain thinning, effectively improve the comprehensive mechanical property of steel, extend its work-ing life, reduce production cost.
