Description
ZAPP Z-Max PM is an ultra high performance HSS produced by powder metallurgy methods that can be heat treated to a maximum attainable hardness of HRc 68-70. It offers maximized levels of wear resistance, red hardness, attainable hardness, and compressive strength compared to other cobalt HSS grades. It is suitable for use in various heavy duty cutting tool applications involving difficult to machine materials as well as selected cold work applications when underhardened to optimize toughness. It can be considered as a possible alternative to carbide when toughness is a concern. The particle metallurgy processing also provides improved machinability, grindability, heat treat response, and dimensional stability when compared to similar grades produced by conventional methods.
