Abstract
The invention discloses high-strength alloy steel. The high-strength alloy steel is characterized by containing the following chemical element ingredients in percentage by mass: 0.3-0.4% of carbon, 0.8-1.25% of silicon, 1.7-1.9% of manganese, 1.1-1.3% of molybdenum, 2.4-2.6% of nickel, 1.3-1.5% of chromium, 0.6-0.8% of potassium, 0.2-0.4% of tungsten, not greater than 0.04% of S, not greater than 0.04% of P and the balance of iron. The alloy steel provided by the invention is high in hardness, relatively good in toughness, good in wear resistance, high in thermal strength, resistant to corrosion, relatively high in fatigue strength, good in casting performance, high in the yield of castings, and worthy of popularization.
Description
Technical field
The invention belongs to technical field of metal, be specifically related to a kind of high strength alloy steel.
Background technology
The environment of present use steel product is various, badly, very high to the requirement of material, current steel alloy has varied, technology has very much progress, but still have a lot of problem to exist, as wear resistance, hardness, rustless property, corrosion resistance nature, high and low temperature resistance, fragility, toughness etc., the requirement of production can't be met in a lot of occasion, also require further improvement, to enhance productivity, reduce costs, improve security, for high-quality precision and sophisticated technology development provides safeguard, create an iron and steel power, for social development provides power.
Summary of the invention
For solving the problem, the invention discloses a kind of high strength alloy steel, there is high rigidity, wear-resisting, corrosion-resistant, impact-resistant advantage.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of high strength alloy steel, is characterized in that: the chemical element composition that it contains and mass percent thereof are: carbon 0.3-0.4, silicon 0.8-1.25, manganese 1.7-1.9, molybdenum 1.1-1.3, nickel 2.4-2.6, chromium 1.3-1.5, potassium 0.6-0.8, tungsten 0.2-0.4, S≤0.04, P≤0.04, surplus are iron.
One as invention is improved, and the chemical element composition that it contains and mass percent thereof are: carbon 0.4, silicon 1.2, manganese 1.7, molybdenum 1.3, nickel 2.6, chromium 1.5, potassium 0.6, tungsten 0.3, S:0.03, P:0.04, surplus are iron.
The invention has the beneficial effects as follows:
Steel alloy provided by the invention not only has high hardness, but also has good toughness, and wear resisting property is good, heat is strong high, corrosion-resistant, also has higher fatigue strength, and good casting property, casting yield is high, is worthy to be popularized.
