C45N

C45N

1.1730 is medium carbon unalloyed tool steel grade offering reasonable tensile strength. This grade can be hardened and tempered to produce a good surface hardness with moderate wear resistance. 1.1730 is widely used for components that require good machinability and wear resistant properties but does not justify the costs of an alloyed tool steel. Available from stock as cut plate.
