C 45 W
Delivery Method : Normalized, annealed 180-220HB
Uses : Non-alloy cold work tool steel. The difference from C 45 is that it has a cleaner and homogeneous microstructure due to its production method. It is used in mold and machine parts and mold holders that do not require hardening. High chip removal feature
