Description

Z-M4 PM is a tungsten molybdenum-vanadium high speed steel produced by powder metallurgy methods. It offers an excellent combination of wear resistance, red hardness, and toughness properties which can provide superior tool performance in a broad range of cutting tool and cold work tooling applications. It is an excellent upgrade over standard M2 high speed and D2 tool steel. The particle metallurgy processing also provides improved machinability, grindability, heat treat response, and dimensional stability when compared to similar grades produced by conventional methods.

Typical applications

• cutting tools
• punches and dies
• fine blanking tools
• shears, rotary shears
• PM compacting tools
• cold extrusion dies
• broaches o reamers
• milling tools
