CK45 carbon steel round bar is a popular choice in German standards due to its average carbon content of 0.45%. As a medium carbon steel, it offers excellent tensile properties and machinability. These features make it an ideal choice for machinery manufacturing. Moreover, CK45 carbon steel is a non-alloy material that provides reliable performance. Therefore, it is widely used in a variety of applications, ranging from construction machinery to agricultural equipment. With its high-quality properties and reliability, CK45 carbon steel continues to be an essential material in the modern industrial world.
Generally supplied in an untreated or normalized state, CK45 round bar can be formed through hot rolling and forging. By subjecting it to additional heat treatment, such as quenching and tempering, the overall properties of C45 carbon steel round bar can be enhanced.
