ISO9001 Railroad Car Axle CNC Machining En13261 Standard Kingrail

A steel material for ISO9001 Railroad Car Axle CNC Machining En13261 Standard Kingrail. Contains the following ingredients: 0.46～0.58wt% of C, 0.17～0.40wt% of Si, 0.75～1.00wt% of Mn, ≤0.015wt% of P, ≤0.010wt% of S, 0.18～0.25wt% of Ni, 0.20 to 0.27 wt% of Cr, ≦0.15 wt% of Cu, ≦0.10 wt% of Mo, 0.02 to 0.08 wt% of V, 0.015 to 0.045 wt% of Al, etc., with the balance being Fe. The process flow of the present invention is: electric furnace smelting or converter smelting → LF furnace refining → RH or VD vacuum treatment → continuous casting → slow cooling or hot delivery → forging heating → hydraulic press forging billeting → forging billet heating → rolling → slow cooling →Normalizing and tempering. Therefore, the shaft material produced by KINGRAIL is dense and uniform.
