Annealed machinability can still be cold plastic deformation low, poor welding. By moderate load plate spring, 7-20mm diameter coil spring and spring washer spring ring. High wear resistance parts, such as grinding machine spindle, collet chuck, precision machine screw, cutter, screw rings on roller bearings, railway and other rail.
