Performance Characteristics:
Cold work mould steel, similar to ASTM A2,it is a kind of widely used steel in A. Good wear resistance, minimal distortion, good quench-hardening ability, high pressure strength.
Applications:
Air hardening tool steel which is easier to machine than D2 or D3 but offers high abrasion resistance with good toughness. steel for pressing mold and cutting knife with heavy-loading and complex shape.
