HCHCR
High Carbon High Chromium (HCHCr) steel, also known as D3 steel, is a type of tool steel extensively used in the manufacturing of dies, punches, cutting tools, and various other applications where high wear resistance, excellent hardness, and good toughness are required.
HCHCr steel is widely used in the manufacture of dies, punches, and other tooling for stamping, blanking, and forming operations. It is utilized in the production of cutting tools such as slitters, shear blades, and guillotine knives due to its high wear resistance and toughness. HCHCr steel finds applications in various cold work applications requiring high hardness and wear resistance, such as cold forging, cold heading, and cold drawing.
