Product Details

SCr415 is a low carbon alloy carburized structural steel with good cold deformation plasticity and weldability. SCr415 is used for the carburizing parts with high working speed and small cross section and high core toughness, such as bushing, crank pin, piston pin, piston ring, coupling, as well as the gear, CAM, shaft and bearing ring with high working speed, ship main engine with screws, locomotive small parts, steam turbine sleeve ring and so on.
