由洛阳第一拖拉机厂为主要负责单位承担的国家“七五”重点科技攻关项目“40MnV(Ti)锻造用非调质钢新钢种的应用研究”,目前在北京通过国家技术鉴定。非调质钢是国际上七十年代发展起来的一种节能型钢种,它以中碳钢为基础,利用微合金化技术和控轧(锻),控冷技术,不经过热处理,达到中碳钢和某些低合金钢调质态的性能。可以用来制造拖拉机,汽车和工程机械上的各种轴杆类零件。具有节省能源,简化生产工艺,缩短生产周期,减少
By Luoyang first tractor factory as the main responsible unit assume “Seventh Five-Year” key scientific and technological project “40MnV (Ti) forging of non-quenched and tempered steel new steel application”, at present in Beijing through national technical appraisal. Non-quenched and tempered steel is an energy-saving steel developed in the 1970s. It is based on medium-carbon steel and uses micro-alloying technology and controlled rolling (forging) and controlled cooling technology without heat treatment to achieve medium-carbon Steel and some low-alloy steel tempered state properties. Can be used to make a variety of shaft parts for tractors, cars and construction machinery. With energy saving, simplify the production process, shorten the production cycle and reduce
