Abstract��Abstract:In this paper,higer nitrogen content in rail steel about U71Mn used by high speed train aimed,quality of rail steel affected by nitrogen,distribution of nitrogen in each working site and factors resticting nitrogen content in steel are studied.Result shows that fracture toughness of rail steel is decreasing while nitrogen content in steel increasing.Nitrogen content in steel is effectively controlled by adding-carbon agent changed from asphalt coke to anthracite.
