Abstract
The invention discloses an alloy steel material for a pump shaft. The alloy steel material comprises the following chemical elementary compositions in percentage by mass: 0.5-0.6% of carbon, 7.6-7.8% of nickel, 0.2-0.4% of chromium, 3.0-3.2% of manganese, 0.3-0.5% of silicon, 0.03-0.05% of molybdenum, 0.01-0.03% of cerium, 0.02-0.04% of magnesium, 0.006-0.008% of tungsten, less than or equal to 0.01% of P, less than or equal to 0.01% of S and the balance of iron and inevitable impurities. The alloy steel material disclosed by the invention is prepared from the multiple elements by reasonably setting a ratio, has relatively good comprehensive mechanical property, high abrasive resistance and hardness, relatively good toughness, relatively high fatigue strength and good casting property and is high in rate of finished products. The alloy steel material is used for the pump shaft, so that the service life of the pump shaft is prolonged.
Description
Technical field
The present invention relates to metal material field, relate in particular to a kind of alloy steel material for pump shaft.
Background technology
The development of steel alloy has had the history of more than 100 year, and up to the present, diversified steel alloy is employed industrial, mainly contains with Types Below: quenched and tempered steel, spring steel, tool steel, rapid steel, die steel, high, normal, basic carbon alloy steel etc.The steel alloy that pump shaft is used has varied, technical growing a lot, still, still have a lot of problems to exist, as fastness to rubbing, hardness, rustless property, corrosion resistance nature, fragility, toughness, cost etc. can not be taken into account, can't meet the requirement of production in a lot of occasions, also require further improvement, to enhance productivity, reduce costs, improve security, for high-quality precision and sophisticated technology development provides safeguard, for social development provides power, task is also very arduous.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of alloy steel material for pump shaft is provided, there is high wear resistance and hardness, toughness and higher fatigue strength preferably, and good casting property, casting yield is high, long service life.
The present invention adopts following technical scheme to achieve these goals:
For an alloy steel material for pump shaft, chemical element composition and mass percent thereof that it contains are: carbon 0.5-0.6, nickel 7.6-7.8, chromium 0.2-0.4, manganese 3.0-3.2, silicon 0.3-0.5, molybdenum 0.03-0.05, cerium 0.01-0.03, magnesium 0.02-0.04, tungsten 0.006-0.008, P≤0.01, S≤0.01, surplus are iron and inevitable impurity.
Preferably, the described alloy steel material for pump shaft, chemical element composition and mass percent thereof that it contains are: carbon 0.55, nickel 7.7, chromium 0.3, manganese 3.2, silicon 0.5, molybdenum 0.04, cerium 0.02, magnesium 0.03, tungsten 0.007, P≤0.01, S≤0.01, surplus are iron and inevitable impurity.
Preparation method: scrap iron is dropped into fusing in stove and, as ferrous substrate source, carry out desulfurization, deoxidation, alloying, the refining of employing refining agent, casting, casting postheat treatment etc.
In the present invention, the content of carbon is controlled at 0.5-0.6, ensures the cooperation of intensity, hardness and toughness that alloy material obtains, and carbon content is too high, and the hardness of material can improve, but toughness can decline; The content of nickel, chromium is controlled at respectively 7.6-7.8 and 0.2-0.4, has ensured that material has high erosion resistance; Silicon obviously improves the castability of foundry goods.
Compared with the prior art, beneficial effect of the present invention is as follows:
Alloy steel material of the present invention uses multiple element, by proportioning is rationally set, the alloy material forming has good comprehensive mechanical property, there is high wear resistance and hardness, toughness and higher fatigue strength preferably, and good casting property, casting yield is high, for pump shaft, extend work-ing life.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
For an alloy steel material for pump shaft, chemical element composition and mass percent thereof that it contains are: carbon 0.5-0.6, nickel 7.6-7.8, chromium 0.2-0.4, manganese 3.0-3.2, silicon 0.3-0.5, molybdenum 0.03-0.05, cerium 0.01-0.03, magnesium 0.02-0.04, tungsten 0.006-0.008, P≤0.01, S≤0.01, surplus are iron and inevitable impurity.
The chemical element composition and the mass percent thereof that contain for the alloy steel material of pump shaft are exemplified below table:
The present invention for the mechanical property of pump shaft alloy steel material is: tensile strength is more than 998MPa, and more than yield strength 867MPa, unit elongation is more than 23%, more than impelling strength 68J/cm2.
