DIN 17350 1.2328 Introduce
DIN 17350 1.2328 is a type of tool steel, which are alloys used for cutting and machining. These alloys are suitable for machining in areas that require high hardness and wear resistance, such as milling cutters and plastics molding tools. Since the 1920s, this type of tool steel has been used to make industrial tools, machine parts and consumer goods.
