C45 Plates

C45 grade steel is a medium carbon steel offering moderate tensile strengths.

This grade is most commonly supplied in an untreated or normalised condition and is available in several variations which offer slight modifications of chemical composition.

Machinability similar to that of mild steel can be expected, however weldability is reduced.
