C-45/EN8
IT IS A MEDIUM CARBON STEEL WITH GOOD FORMING AND BENDING PROPERTIES. PARTS MADE OF THIS STEEL CAN BE HARDENED AND TEMPERED TO ACHIEVE THE REQUIRED HARDNESS. DUE TO ITS LOW CONSUMPTION, IT IS NOT AVAILABLE IN STOCK BUT WE SUPPLY AGAINST SPECIFIC ORDERS. MINIMUM ORDER QUANTITY AND LEAD TIME DEPENDS ON THE REQUIRED SIZE.
The material can be molded with hardening by means of quenching and tempering on focused and restricted areas. C45 can also be instigated with induction hardening up to the hardness level of HRC 55. This grade is in majority situations delivered in an unattended heat treatment state i.e. normalized condition.
However on demand it can be furnished in numerous heat treatment variations which is shown by additional letters in the name of grade. This can be furnished with minor changes in chemical composition. Machinability of C45 is equivalent to that of mild steel, on the other hand weld ability is exhibited lower than that of mild steel.
