C45 steel is a kind of high strength, high quality carbon steel. It is usually used in normalized condition because of weak harden-ability. It will be tempered when it has high requirements for mechanical properties. C45 steel is usually made to components which need high strength, such as gear, shaft, piston pin, etc. It is also used for mechanical parts, forging, stamping parts, bolts, nuts and pipe joints.
