DESCRIPTION ZAPP

Z-M48 PM is a tungsten-moly-vanadium-cobalt (super-) high speed steel produced by powder metallurgy methods that can be heat treated to a maximum attainable hardness of HRc 67-69. It offers high levels of wear resistance, red hardness, and compressive strength which make it suitable for use in various heavy duty cutting tool applications involving difficult to machine materials. It can be effective in select cold work applications when underhardened to optimize toughness. 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

• form tools
• gear tools
• broaches
• misc. cutting tools
• precision wear parts
• roll forming tools
• punches and dies
