Description
Technical field
The present invention relates to a kind of material steel, belong to steel field, the high-strength material steel of more particularly to a kind of Low temperature-resistancorrosion-resistant corrosion-resistant.
Background technology
Extraordinary Low temperature-resistancorrosion-resistant corrosion-resistant steel is now mainly used in the machinery manufacturing industry such as petroleum industry, instrument and meter, standard component.More than 4,000,000 tons, wherein half is by the U.S., Japan's production for the current whole world year consumption.The extraordinary low temperature resistant steel demand of China in 2013 is about 40~500,000 tons, and China's annual production needs a large amount of imports only more than 30,000 ton.With the development of China's modernization industry, extraordinary low temperature resistant steel market potential is huge.
In field of hydraulic equipment, such as hydraulic pump, hydraulic cylinder equipment, because working environment is harsh to the requirement of equipment service behaviour.The particularly hydraulic component such as valve sealing element, piston rod, piston cylinder, due to the influence of its use environment, it is usually damaged because of reasons such as low temperature, abrasion, corrosion, conventional hydraulic material is mostly some nickel-chrome alloy steels, carbon steel etc., the parts that these materials are made can only ensure that a certain item performance is protruded mostly, and overall performance can not be improved, in varying environment, in the case of different use conditions, medium, can not all be applicable well mostly, need it is particularly customized or restructure, to equipment using bringing very big inconvenience.
In some Special sections, such as northeast China, Russian Siberia, temperature is likely lower than subzero five or six ten degree in the winter time for part region, and many hydraulic tests all cannot be used normally under this low temperature environment, be unable to bear low temperature environment and easily freezed cracking.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided a kind of high-strength material steel of Low temperature-resistancorrosion-resistant corrosion-resistant, the material hardness of steel is high, with good low temperature resistant and corrosion resistant effect.
To solve above-mentioned technical problem, the present invention uses following technical scheme：
A kind of high-strength material steel of Low temperature-resistancorrosion-resistant corrosion-resistant, the component of the structural steel（Hereinafter it is weight percentage）For：Carbon 0.075%~0.09%, silicon 0.3%~0.4%, manganese 1.0%~1.5%, phosphorus 0.005%~0.013%, sulphur 0.005%~0.01%, nickel 0.3%~0.4%, chromium 0.1%~0.2%, copper 0.1%~0.2%, tungsten 0.005%~0.013%, molybdenum 0.005%~0.013%, titanium 0.001%~0.008%, vanadium 0.001%~0.005%, aluminium 0.015%~0.025%, arsenic 0.013%~0.02%, tin 0.01%~0.02%, balance of iron.
The component of the structural steel（Hereinafter it is weight percentage）For：Carbon 0.087%, silicon 0.35%, manganese 1.33%, phosphorus 0.01%, sulphur 0.008%, nickel 0.35%, chromium 0.16%, copper 0.16%, tungsten 0.01%, molybdenum 0.01%, titanium 0.005%, vanadium 0.003%, aluminium 0.021%, arsenic 0.016%, tin 0.014%, balance of iron.
Compared with prior art, the beneficial effects of the invention are as follows：Under original working condition, by optimization, design component, so as to improve the overall performance of material steel, steel is good, and particularly each mechanical property is very excellent, and security, reliability are greatly enhanced, meet high intensity, the use environment of cryogenic high pressure, the hydraulic test that material steel of the invention is made can be operated under subzero 70 ° of adverse circumstances, greatly improve the adaptability of equipment, reduce the spoilage of equipment.
Specific embodiment
With reference to specific embodiment, the present invention is further illustrated.Embodiments of the present invention include but is not limited to the following example.
A kind of high-strength material steel of Low temperature-resistancorrosion-resistant corrosion-resistant, the component of the structural steel（Hereinafter it is weight percentage）For：Carbon 0.075%~0.09%, silicon 0.3%~0.4%, manganese 1.0%~1.5%, phosphorus 0.005%~0.013%, sulphur 0.005%~0.01%, nickel 0.3%~0.4%, chromium 0.1%~0.2%, copper 0.1%~0.2%, tungsten 0.005%~0.013%, molybdenum 0.005%~0.013%, titanium 0.001%~0.008%, vanadium 0.001%~0.005%, aluminium 0.015%~0.025%, arsenic 0.013%~0.02%, tin 0.01%~0.02%, balance of iron.
In the component of the present embodiment, manganese content is higher, higher with the manganese sulfide inclusion content that sulphur is formed such that it is able to strengthen the intensity of Steel material, disclosure satisfy that the demand of complicated procedures of forming, also easier to process during manufacture high-precision hydraulic device, is hardly damaged.
In the steel grade of prior art,Contain sulphur higher mostly,Phosphorus,Cut and also contain copper higher,These elements are totally unfavorable to the thermoplasticity of steel,So,General steel grade is required for carrying out desulfurization,The operation of dephosphorization,Control content is less than certain numerical value as far as possible,This is higher to procedure calls,Virtually increased cost and manufacturing time,The present embodiment is in order to solve this problem,Tungsten is added in component,Molybdenum,Titanium,Vanadium,Tin,Aluminium,Nickel and chromium concentrate element,So as to the above-mentioned element when smelting can be with sulphur and phosphorus action-reaction,Generation alloy,So as to avoid sulphur and phosphorus content problem how high,Entirety not only increases the thermoplasticity of steel,Also improve the intensity of steel grade,Hardness and lower temperature resistance,Improve steel grade overall performance,Simultaneously,The present embodiment is exactly to add rare element arsenic in a unexpected inventive point,Arsenic canescence,There is the ingot of metallic luster,Matter is crisp poisonous,Can typically use with caution,But designer considers that arsenic interlocks the double-decker that the hexatomic ring holded up is constituted by many,Because adhesion between layers is weak,Therefore it is crisp and hard,Designer once chances on,Add the steel grade practised after arsenic,It can be with internal plurality of impurities when smelting,Copper,Phosphorus reaction,So as to form arsenide,The low temperature resistant high pressure of steel grade is improve on the contrary,Speciality that is corrosion-resistant and increasing intensity,And certain catalytic effect can also be played,Improve the reaction rate of rare metal and spend completely,So as to further increase the properties of steel grade,So that the steel grade alloy content is high,Function admirable stabilization,Particularly its intensity is high,With low temperature resistant well and corrosion performance,It is particularly well-suited to the hydraulic test of some cryogenic high pressures or the materials demand of parts,Show through overtesting,The hydraulic test that material steel of the invention is made can be operated under subzero 70 ° of adverse circumstances,Greatly improve the adaptability of equipment,Reduce the spoilage of equipment.
