Effect of Mn on hardenability of 25CrMo axle steel by an improved end-quench test
With the sixth large-scale railway speed-up, the quality of the axles is essential to the safety of the locomotive.According to the Frames high-speed axle technical standard for the control of alloy elements in axle steel, optimization experiments of 25CrMo steel composition were performed by vacuum inductive melting.In order to study the hardenabi
