C45 steel is a medium carbon steel offering moderate tensile strengths.
C45 steel material is capable of throughout hardening by quenching.
a rapid quench for increased hardness throughout the material.
Tempering on limited sections but can also be flame or induction hardened to HRC 55.
The C45 steel grade is most commonly supplied in an untreated or normalized condition.
it is available in several variations (denoted by additional letters) which offer slight modifications of chemical composition.
easy Machinability similar to that of standard grade mild steel can be expected, however, weldability is reduced.
