Abstract
The invention discloses high-strength alloy steel. The high-strength alloy steel contains, by mass, 5%-10% of chromium, 3%-5% of molybdenum, 1%-3% of tungsten, 0.5%-1.5% of manganese, 1%-5% of nickel, 0.5%-1.5% of vanadium, 0.5%-1.5% of silicon and the balance Fe and impurities. According to the high-strength alloy steel, alloy elements are added, and the composition structure of the steel is optimized, so that the high-strength alloy steel has good compression resistance and impact resistance, and the service life of alloy steel components is prolonged.
Description
Technical field
The present invention relates to a kind of stainless material, be specifically related to a kind of high strength alloy steel.
Background technology
Steel are nation-building and requisite valuable cargo of realizing the four modernizations, and it is widely used, various in style, have been deep into the every aspect in people's daily life.But in the industrial production, part steel parts can carry out shock operation or load-bearing operation often; very high to the requirement of strength of steel, but the intensity of current steel should be not; continuing to carry out to clash into or after load-bearing operation, easily occur crackle, work-ing life is shorter.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of and form structure by interpolation alloying element, optimization steel thus possess the steel alloy of high strength.
To achieve these goals, present invention employs following technical scheme:
A kind of high strength alloy steel, with the quality of this high strength alloy steel for benchmark, chromium, the molybdenum of 3 ~ 5%, tungsten, the manganese of 0.5 ~ 1.5%, nickel, the vanadium of 0.5 ~ 1.5%, silicon, the surplus of 0.5 ~ 1.5% of 1 ~ 5% of 1 ~ 3% that described high strength alloy steel contains 5 ~ 10% are iron and impurity.
Further preferably: chromium, the molybdenum of 4%, tungsten, the manganese of 1%, nickel, the vanadium of 1%, silicon, the surplus of 1% of 3% of 2% that described high strength alloy steel contains 8% are iron and impurity.
Described impurity comprises carbon, phosphorus, the sulphur of trace.
High strength alloy steel of the present invention, by adding the elements such as chromium, molybdenum, tungsten, vanadium, silicon, optimizes the alloy proportion of its steel matrix, improves its crushing resistance, anti-collision performance.
Carry out some to the performance of some component elements that the present invention adopts below to introduce:
Chromium (Cr), chromium can improve hardenability and the tempering resistance of steel effectively, improve the intensity of steel, and chromium can also reduce the activity of carbon, improve the leaching carbon of steel, and form fine carbide, the steel surface decarburization in heating, rolling and heat treatment process and greying tendency can be reduced, improve toughness and wearability; But, during chromium too high levels, form the carbide of chromium on the contrary in a large number, worsen bullet subtractive energy and the toughness of steel.Therefore, in the present invention, the content controlling Chromium in Alloy steel is 5 ~ 10%(weight percent), optimum content is 8%.
Molybdenum (Mo), molybdenum is steel alloy non-corrosive, corrosion resistant key element; Therefore, the performance of molybdenum additives alloy steel has very large impact, and a small amount of molybdenum is added among steel, and steel can be made to have very excellent performance, greatly can increase the wear resisting property of steel, increase the service life.Steel alloy can improve steel hardness, intensity and toughness containing molybdenum, and the good weldability of tool and corrosion resistance.After cast iron adds appropriate molybdenum, will greatly improve tension, bending resistance and fatigue resistance, also can improve the homogeneity of casting structure, this especially seems important to massive casting, these foundry goods are widely used in automobile making, pressure pipeline and mold etc., and in processing industry, molybdenum is used more extensive.Utilize thermal expansivity little, heat conduction be strong, molybdenum that high strength is good or molybdenum base alloy, die life significantly extends; Add the performance that alloying element just can improve them in Xiang Tie, steel and other metal, as hardenability, under intensity, erosion resistance and resistance to abrasive property.But during the too high levels of molybdenum, then worsen the plasticity of steel alloy, toughness and processing characteristics.Therefore, in the present invention, the content that contriver controls molybdenum in steel alloy is 3 ~ 5%(weight percent), optimum optional 4%.
Tungsten (W), the physical features of tungsten is very strong, and in alloy, add a small amount of tungsten can greatly increase heavy alloyed intensity and wear resisting property.In the present invention, the content controlling tungsten in steel alloy is 0.5% ~ 1.5%, and optimum content is 1%.
Nickel (Ni), nickel has good over-all properties, can resistance to various acid corrosion and stress corrosion, and property is tough and tensile, is magnetic and good plasticity-, and welding property might as well; Under 650 ~ 1000 DEG C of high temperature, have higher intensity and anti-oxidant, resistance to combustion gas corrosion ability, be most widely used in superalloy, that hot strength the is the highest class alloy.In the present invention, the content controlling nickel in steel alloy is 1% ~ 5%, and optimum content is 3%.
High strength alloy steel of the present invention adopts conventional production process, is specially:
(1) raw material is carried out just refining; (2) refining; (3) cooling forming; (4) rolling; (5) quench; (6) tempering; (7) coating, namely obtains high strength alloy steel finished product.
Advantage of the present invention:
High temperature resistant, resistance to compression anti-collision performance is high, long service life.The technical scheme that the present invention proposes is in the problem fundamentally solving steel frangibility, easily crack, molybdenum ore, nickel minerals, tungsten ore, navajoite etc. are increased in the material preparing steel, make the element such as molybdenum, tungsten, chromium, nickel, vanadium containing rational proportion in steel alloy finished product, greatly increase the strength property of steel alloy, extend its work-ing life.
