Optimization of Composition and Rolling Process for SS Steel Grade Carbon Steel Rail Satisfied American Standard
The SS steel grade rail with 60E1 cross section is manufactured with small batch production by comparing the rails with 60E1 and 115RE cross sections,optimizing chemical composition,adopting narrow composition control,in-creasing C content,controlling contents of Mn and Cr as well as optimizing rolling process. The rail performances could reach Rp0.2 ≥512 MPa,Rm≥982 MPa,A≥10% and tread hardness (HB)≥310. The small batch industrial production practices prove that the production process of SS steel grade rail with 60E1 cross section is trouble free and its performances are stable,which could meet the user needs so that it can be produced with incremental quantity.
