Alloy tool steel: 105WCr6
● Features and Scope:
Is more widely applied cold work die steel, known as "deformation of steel", but more sensitive to network carbide formation. The main requirements when used as a hardening deformation is small, long and complex shape of the cutting tool (such as broaches, taps long, long reamers, special cutter) and measuring tools (such as die, block gauge, gauge, like columns, sample sets) and the cross-sectional shape of small and complex precision Die like.
