60Si2MnA: Common Material For Railway Elastic Clip

Sep 02, 2025 Leave a message

Rail clip is a component of railway fastening systems. It is used to fix the railroad track to the underlying baseplate and sleepers. The clamping force by rail clips helps to maintain the gauge and prevent the rail from moving in the vertical and horizontal direction relative to the sleeper.
