35CrMo是合金结构钢(合金调质钢)的规格编号,该钢材主要用于制造承受冲击、弯扭、高载荷的各种机器中的重要零件35CrMo alloy structure steel (alloy quenched and tempered steel) the specification number, the steel is mainly used for manufacturing bear the important parts of the impact, bending and torsion, high load on the various machines35CrMo合金结构钢,有很高的静力强度、冲击韧性及较高的疲劳极限,淬透性较40Cr高,高温下有高的蠕变强度与持久强度,长期工作温度可达 500℃;冷变形时塑性中等,焊接性差。低温至-110摄氏度,并具有高的静强度、冲击韧度及较高的疲劳强度、淬透性良好,无过热倾向,淬火变形小,冷变形时塑性尚可,切削加工性中等,但有类回火脆性,焊接性不好,焊前需预热至150~400摄氏度,焊后热处理以消除应力,一般在调质处理后使用,也可在高中频表面淬火或淬火及低、中温回火后使用。舞钢生产执行标准:GB/T11251-2009、舞钢企业标准、***标准、交货状态:正火或正火+回火、调质。35CrMo alloy structure steel, very high static strength, impact toughness and high fatigue limit and hardenability of was higher than that of the 40Cr and high temperature with high creep strength and rupture strength, long-term working temperature of up to 500 DEG C; when the cold deformation plastic medium and poor weldability. Low temperature to - 110 degrees Celsius, and has high static strength, impact toughness and high fatigue strength, hardenability excellent, no tendency to overheat, quenching deformation small, when the cold deformation plastic fair and cutting medium, but the first kind temper brittleness, welding is not good, before welding to preheated to 150-400 Celsius degree, post weld heat treatment to eliminate stress, generally used in quenching and tempering treatment can also be used in high frequency surface quenching or quenching and low temperature tempering after. Wugang production standards: GB/T11251-2009, Wugang enterprise standards, industry standards, delivery status: normalizing or normalizing + tempering, quenching and tempering.
35crmo用于制造承受冲击、弯扭、高载荷的各种机器中的重要零件,如轧钢机人字齿轮、曲轴、锤杆、连杆、紧固件,汽轮发动机主轴、车轴,发动机传动零件,大型电动机轴,石油机械中的穿孔器,工作温度低于400摄氏度的锅炉用螺栓,低于510摄氏度的螺母,化工机械中高压无缝厚壁的导管(温度450~500摄氏度,无腐蚀性介质)等;还可代替40CrNi用于制造高载荷传动轴、汽轮发动机转子、大截面齿轮、支承轴(直径小于500MM)等;工艺上的设备材料、管材、焊材等等。用作在高负荷下工作的重要结构件,如车辆和发动机的传动件;汽轮发电机的转子、主轴、重载荷的传动轴,大断面零件。数据显示,3月上旬重点钢企粗钢日产估算值为163.58万吨,环比减2.52%;全国估算值为207.61万吨,环比减1.80%。看到这里估计有人会问,钢价从三月初到现在已经涨上天了,钢厂为何不赶紧加大生产赚钱呢?对此分析师认为:首先,钢材市场价格,是在上旬出现的暴涨,而彼时多数钢企排产为前期订单,新增的大量订单很难快速排进生产计划,所以即便产量因订单增加出现爆发,也很有可能是在三月中旬乃至下旬。报告指出,一个强大的钢铁行业构成了许多产业价值链的基础。欧洲的钢铁行业每年的证券交易额达到1660亿欧元,占欧盟GDP的比重为1.3%。2015年,钢铁业为欧盟提供了32.8万个直接就业机会,以及更多的相关就业机会。虽然存在很大发展潜力,但欧盟在全球钢铁市场的竞争地位在过去几年不断恶化。为应对这种新局面,欧盟委员会在报告中称,需要短期和长期措施。报告称,这些措施具体包括加强贸易防御措施的实施;努力推动各项相关进程的进展;贸易防御机制的现代化问题,其中包括进一步提高欧盟委员会行动的效率和有效性,快速实施征税,移除“从轻征税”规则,加强事前监管等措施以及对当前的欧盟《反倾销基本条例》作出修订等;以及解决全球钢铁产能过剩问题。其次,虽然钢价的确是上天了,但矿价却早就飞离地球了,所以钢厂的生产成本提高的幅度,显然是要大于成材价格的提高。如此一来,其生产利润也并未有太多改观,那么生产动力自然也就不会太强了。35CrMo for important parts of various machine manufacturing, to withstand the impact of bending and high load in, such as the rolling mill herringbone gear, crankshaft, hammer rod, connecting rod, fasteners, turbine engine main axle, engine, transmission parts, large motor shaft, punch in the petroleum machinery, with the bolt working temperature is below 400 degrees Celsius boiler the nut, below 510 degrees Celsius, the catheter in chemical machinery of high pressure seamless thick walled (temperature of 450~500 degrees Celsius, non corrosive medium); also can replace 40CrNi for the manufacture of high load transmission shaft, steam turbine rotor, large section gear, Zhi Chengzhou (diameter less than 500MM); the process of equipment and materials pipe, welding, etc.. Used as an important part of the work under high load, such as the transmission parts of the vehicle and the engine; the rotor, the main shaft and the heavy load of the turbine generator.
