Abstract: Gear steel of high speed locomotive was used in the condition of more than 250 km / h high- speed locomotive traction. That is high- grade carburizing gear steel,with high strength,high wear resistance,high ductility and toughness,is widely used in the industrial reducers of various types of mines,ports,and high- speed locomotive traction gears and other aspects. Since the trial production and development Heilongjiang Metallurgical Institute continues the in- depth research,and constantly improves the technology,using high power EAF + LF + VD,thermally sending ingot,rolling or forging,and annealing process,with advanced technology and stabile quality and performance.
Keywords: gear steel; steel-making; high speed locomotive
