About 45# Carbon Steel (SAE 1045 / DIN C45)
45# steel is a medium-carbon engineering steel known for its balance of strength and ductility. It is the "workhorse" of the industry, offering good tensile strength and excellent machinability. While it is generally supplied in a hot-rolled or normalized condition, it responds well to heat treatment (quenching and tempering) to enhance its mechanical properties. It is widely used for manufacturing shafts, gears, connecting rods, and mold bases where high precision and moderate strength are required.
