X45NiCrMo4 / AISI: 6 F 7
Delivery Method : Normalized, annealed 180-220HB
Uses : It is a cold work tool steel with high hardenability and very high toughness. It is widely used in forks, spoons, knives and mint molds, cutting dies where thick sheets are cut, cold forging and shaping tools, and patterning and bending dies. Since it can be polished, it can be preferred in some plastic molds. Impact resistance is very high.
*Time interval varying depending on the section.
