M4PM™ Tool Steel: Increase Uptime, Lower Product Costs and More!

Mate’s proprietary, premium M4PM™ tool steel is designed for use in high-performance tooling systems. M4PM™ tool steel is a high-speed particle metallurgy steel that combines the chemical composition of M4, particle metallurgy manufacturing and a triple temper heat treatment process. M4PM offers superior resistance to adhesive and abrasive wear, which maximizes regrind intervals. The increased alloy content results in higher effective hardness for better wear resistance. In addition, a more uniform distribution of smaller carbides results in significantly reduced tool breakage and edge chipping.

M4PM tool steel gives you longer-lasting tooling. Compared to conventional high-speed steel used by other manufacturers, Mate tooling with M4PM provides at least 50% or greater wear resistance (see chart at left). With the clear advantage of M4PM steel, Mate’s superior accuracy and precision, you have a winning combination: reliable, consistent, long-lasting tooling. So what does long-lasting tooling mean for you?
