摘要
对国内铁路列车转向架用钢从1950年至2010年的材质变化和性能要求进行了概述;同时对铸钢和焊接式转向架用钢的化学成分设计、强度级别、耐大气腐蚀性能等进行了简要介绍;着重对现有高速列车转向架用钢的低温韧性、耐大气腐蚀性能、焊接性能和疲劳性能的研究现状进行了梳理。
The material changes and property requirements of domestic railway bogie steel from 1950 s~2010 s are summarized.At the same time,the chemical composition design,strength grade and atmospheric corrosion resistance mechanism of steel for cast steel and welded bogies are briefly introduced.The research status of low temperature toughness,atmospheric corrosion resistance,welding property and fatigue property of current high-speed train bogie steel is reviewed.
