In twin-screw extruders used for producing high-functionality plastic compounds, the consumption of these parts is becoming serious owing to the increase in a number of hard filler and flame retardants added. We developed a new material, MZ01, using powder metallurgy technology that achieves the long-life of twin-screw extruder parts. The wear resistance and corrosion resistance of MZ01 are much better than those of the conventionally used alloy tool steel SKD11 and powder high-speed steel SKH40. In user evaluation of actual equipment, MZ01 achieved a life span of more than 15 times longer than that of SKD11.
