Clutch Cover
The cover is made of high quality steel pickling plate SPHC (thin) SPHE (thick), and the pressure plate is made of HT250 material. Through the forging process, the mechanical property is better than that of the same material, the tensile strength is 240Mpa, the diaphragm spring is made of 50CRV4 material, through high temperature quenching, tempering, fingertip high frequency and other processes, The hardness is up to 42~48HRC, and then machined to make the pressure plate better in compression property. The service life of the product can reach 50000 kilometers
