Description

Steel C45 is a medium carbon steel designation assigned to steels that have a carbon content between 0.42 and 0.50 wt. %. While medium carbon steels are used in a variety of applications, they are particularly well suited for parts that require high wear resistance and strength such as gears, shafts, and bearings. This material has low thermal conductivity and low ductility among wrought carbon steels. A combination of size accuracy, straightness and concentricity result in minimal wear in high-speed applications.

Key Features

High tensile strength • Low ductility • Low thermal conductivity
