On the basis of these series, some brands added alloying elements such as molybdenum, vanadium or boron in order to improve their performance in some aspects. In addition, other grades of steel, such as quality carbon structural steel, carbon tool steel, high speed tool steel and stainless steel, are selected as spring steel.Classification according to production methodsThe hot rolling steel hot rolling (forging) including bar, Fang Gang, flat steel, steel plate, forging round steel, Fang Gang.The cold drawing (rolling) steel wire, including steel, colddrawn materials (cold drawn steel).Classification according to the delivery status of the steelThe hot rolling (forging) steelA. is rolled in hot (forged) state, and the steel is made into spring by hot forming, followed by quenching and tempering.B. annealed steel is made into spring by cold forming, followed by quenching and tempering.The above shall be in accordance with the relevant delivery conditions, hardness requirements.The cold drawing (rolling) steelA. steel wireLead bath isothermal quenching cold drawn steel wire (also known as cast off cold drawn steel wire) made of steel wire spring only needs to be tempered at low temperature to eliminate stress.Oil quenching and tempering steel wire cold drawn into the required size, continuous heating, continuous oil quenching and lead tempering. The steel wire is made of spring and only needs to be heated at the bottom to eliminate the stress.Cold drawn steel wire (i.e. steel wire without quenching and tempering)A. delivers in cold drawn condition.B. delivered by annealing, normalizing or tempering.The above two kinds of steel wire will be quenched and tempered after being made of spring.B. steel bandAfter cold rolling, the product is made into spring and needs to be tempered at low temperature to eliminate stress.The quenched and tempered state of delivery is made of spring after low temperature tempering, to eliminate stress.Fire and fire should be treated by quenching and temperingC. cold drawn steelThe annealed steel is made into spring by cold forming and then treated by quenching and tempering.Other classification methodsIn addition to the above, there are some other classifications, for example, according to the requirements of delivery conditions, can be divided into chemical components (mechanical properties) delivery and hardenability delivery. According to the working conditions of spring, it can be divided into static load spring steel, withstanding impact load, springsteel, high and low temperature spring and corrosion resisting spring steel, etc..Performance requirements;Spring is used under impact or vibration or long-term stress, so spring steel is required to have high tensile strength, elastic limit and high fatigue strength. The process requires spring steel has a certain hardenability, not easy decarburization, surface quality and other carbon spring steel, that is, carbon content of WC in the 0.6%-0.9% range ofhigh-quality carbon structural steel. Alloy spring steel is mainly Si Mn steel, their carbon content was slightly lower, mainly by increasing the silicon content of Wsi to improve the performance; in addition to Ge, tungsten and vanadium alloy spring steel. In recent years, with China resources, and according to the automobile and tractor design requirements of new technology, developed a new steel added boron, niobium, molybdenum and other elements in the Si Mn steel foundation, prolongs the service life of the spring, improve the quality of spring.Production processThe available oxygen converter furnace and open hearth furnace or general production of spring steel; high quality spring steel or better quality with special properties, furnace or vacuum refining furnace. The content of carbon, manganese, silicon and other major elements in spring steel is narrow, and the chemical composition must be strictly controlled during smelting. When the silicon content is high, it is easy to formbubbles and other defects. After the ingot is rolled and rolled, the cooling is not easy. Therefore, the raw materials used for smelting must be dry, as much as possible to remove gas and inclusions, and to avoid overheating of the steel. Spring steel must pay special attention to decarburization and surface quality during rolling. When the steel surface is seriously decarburization, the fatigue limit of steel will be significantly reduced. Therefore, stop rolling temperature in hot working time should not be too low (less than 850 DEG C), avoid in the temperature range of graphite is easy to form (650 to 800 DEG C) in the long residence time. After the spring is made, shot peening can produce residual compressive stress on the surface of the spring so as to offset part of the working stress on the surface layer and restrain the formation of surface cracks, which can significantly improve the fatigue limit of the spring.1. heat treatmentSpring steel requires higher strength and fatigue limit, and is usually used under the condition of quenching + medium temperature tempering to obtain higher elastic limit. The heat treatment technology has a crucial influence on the inner quality of spring. Therefore, how to further improve the fatigue life of the spring needs further study, especially chemical surface modification, heat treatment and shot peening all have an important influence on the fatigue life of the spring. In order to further strengthen the surface strength, increase the compressive stress and improve the fatigue life of the valve spring, the valve spring is formed,Further nitriding, low temperature liquid carbonitriding, or carbonitriding treatment, followed by shot peening. For example, Japan will f4mm Si CR oil quenched steel wire by 450 * * 4.5H low temperature body carbon nitrocarburizing, and by 400 * 15min moderate temperature tempering comparison, the fatigue limit can be increased by 240mpa. Nitrogen infiltration, not only eliminates the adverse effects of decarburization, but also improve the residual compressive stress, while the high temperature strength of the valve spring by cryogenic liquid nitriding and carbonitriding of deformation at 150 C for 0.2% (the specified value is 0.5%), the deformation of 250 DEG C for 0.56%, thermal stability the valve spring and the relaxation resistant stability, but liquid nitriding and carbonitriding time should be strictly controlled, otherwise it will form a mesh network of sulfide and nitride, it will reduce the fatigue strength. You can also choose to improve the shot peening intensity of valve spring, the production practice of valve spring by two surface shot peening pellets, a diameter of 0.8mm, the microhardness is 720hv0.2, a diameter of 0.25mm, the microhardness is 800hv0.2, three times can reach better effect of shot peening intensity, and can make the surface quality improved.2. alloyingCarbon is the major strengthening element in steel, and affects spring steel more often than other alloy elements. The spring steel material shall be medium high carbon alloy steel according to the application requirements. Nowadays, spring steel is widely adopted in the world, and the majority of carbon content is between 0.45% and 0.65%. In order to overcome thedifficulty of reducing the toughness and plasticity of spring steel, the trend of carbon content reduction is also achieved. Practice has shown that these spring steels can be used in low temperature tempered lath martensite structures, with sufficient strength and excellent comprehensive mechanical properties, especially plasticity and toughness. Several high strength spring steels developed in Japan, such as uhs1900, vhs2000, nd120s, nd250s and so on, have carbon content of about 0.40%. The main role of alloying elements in spring steel is to improve mechanical properties, improve process performance and give certain special properties (such as high temperature resistance, corrosion resistance), etc.. A lot of spring steel with silicon as the main alloying elements, it is the maximum sag resistance effect of alloy elements, this is mainly because silicon has a strong solid solution strengthening effect; at the same time, silicon can inhibit cementite during the tempering process of crystal nucleus formation and growth, change the tempering quantity, the carbide size and precipitation form, improve the stability of tempering steel. At present, the domestic steel brand WSI is 1.8% ~ 2.2%, is the existing standard silicon containing the highest spring steel. But if the silicon content is too high, will promote in steel rolling and heat treatment process of decarburization and tendency of graphitization, and the smelting difficulty and easy to form inclusion, therefore, the use of high silicon content of spring steel still cautious.Because chromium can improve the hardenability of steel, graphite tend to prevent Si CR ball annealing time, reduce decarburization layer, so it is common alloying elements in spring steel, chrome as the main strengthening spring steel50CrV elements are widely used. Manganese is the most effective alloying element for increasing hardenability. It dissolves in ferrite and has a solid solubility. Studies have shown that the WMN must be greater than 0.5% so that the core of the spring steel becomes completely martensite when quenched, but when the WMN is above 1.5%, the toughness decreases significantly, which should be taken into account when choosing the spring steel. Molybdenum can improve the hardenability of steel, prevent temper brittleness and improve fatigue performance. The existing standard molybdenum spring steel is not much, adding amount is generally below 0.4%. Vanadium is a strong carbide forming element, and the dispersed MC carbide produced by solid state has a strong precipitation strengthening effect. Adding 0.11%v in 35crmnb steel, can significantly improve the hardenability of steel, also found that vanadium can effectively reduce the decarburization sensitivity of 35simnb steel and vanadium steel, that effectively reduce dissolved carbon, prevent grain growth and prevent and improve the oxidation resistance of grain boundary diffusion.。

(完整版)弹簧钢的性能介绍

(完整版)弹簧钢的性能介绍

[ 常用牌号 ] :常用合金弹簧钢的牌号、化学成分、热办理、力学性能及用途。

常用的合金弹簧钢有 60Si2Mn 、 50CrVA、30W4Cr2VA 等。

60Si2Mn 钢是应用最广泛的合金弹簧钢,其生产量约为合金弹簧钢产量的80%。

它的强度、淬透性、耐回火性都比碳素弹簧钢高,工作温度达250 ℃,缺点是脱碳倾向较大,适于制造厚度小于 10mm 的板簧和截面尺寸小于 25mm 的螺旋弹簧,在重型机械、铁道车辆、汽车、拖拉机上都有广泛的应用。

30W4Cr2VA 是高强度的耐热弹簧,用于500℃以下工作的[ 弹簧成型方法 ] :对直径或板簧厚度大于 10 mm 的大弹簧,可在比正常淬火温度高出 50~80℃的温度热成形,对直径或板簧厚度小于 8~10mm 的小弹簧,常用冷拔弹簧钢丝冷卷成形。

为保证弹簧拥有高的强度和足够的韧性,平时 50CrVA 钢的力学性能与 60Si2Mn 钢周边,但淬透性更高,钢中 Cr 和 V 能提高弹性极限、强度、韧性和耐回火性,常用于制作蒙受重载荷、工作温度较高及截面尺寸较大的弹簧。

锅炉主安全阀弹簧、汽轮机汽封弹簧等。

常采用淬火 + 中温回火。

对热成形弹簧,可采用热成形余热淬火,对热冷成形的弹簧,有时可省去淬火、中温回火工艺,成形后只需进行200 ~300 ℃进行去应力退火即可。

弹簧钢热办理后平时进行喷丸办理,其目的是在弹簧表面产生节余压应力,以提高弹簧的疲倦强度。

[ 性能 ] :硬度为 40 ~48HRC,有较高的弹性极限和疲倦强度,以及必然的塑性和韧性弹簧是起缓冲、减振和储能等作用。

弹簧一般是在交变应力下工作,常有的破坏形式是疲倦破坏,因此,必定拥有高的信服点和屈强比(σs/ σb)、弹性极限、抗疲倦性能,以保证弹簧有足够的弹性变形能力并能蒙受较大的载荷。

同时,弹簧钢还要求拥有必然的塑性与韧性,必然的淬透性,不易脱碳及不易过热。

一些特别弹簧还要求有耐热性、耐蚀性或在长时间内有牢固的弹性。
