Alloy tool steel: 105WCr6
● Features and application:
Is widely used in cold work die steel, known as "non-deformed steel", but more sensitive to the formation of carbide network. The main requirements for quenching deformation is small, long and complex shape of the cutting tool (such as broaches, taps long, long reamers, special cutters) and measuring (eg, die, block gauge, gauge, like columns, sample sets) and small cross-section and shape of the complex high-precision Die and so on.
