42CrMo4   is  steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening. The surface hardness will exceed min. 53 HRC. 42CrMo4 can be delivered M-treated in order to optimize the machinability

MARKING of 42CrMo4 forged shafts
Each piece of 42CrMo4  forged  material (including the QTC) shall have the clients part number and the mill heat/heat treat number marked onto its surface (hot stamping, low stress stamping with round v or interrupted dot die is preferred).  They shall also have the clients purchase order number durably marked (paint, ink or stamped as above) on their surface. Additional marking may be required by the purchase order.
As an alternative, small products that can be accumulated and palletized, crated or otherwise bundled     securely may be segregated by clients part number and mill heat/charge number. The package shall be marked with the clients purchase order number and part number, and mill/charge number.  This information shall be attached in such a    manner as to be legible upon receipt by clients
