High alloy screw for Injection Molding Machine

High alloy screw materials is powder metallurgy steel, including high-content W, Mo, Cr, V, Si, Co etc, these screw processing technology is machining and vacuum heat treatment, microstructure of screw steel is tempered martensite + carbides. These screws possess excellent strength and toughness, high hardness, and excellent corrosion resistance, are suitable for halogen free and high glass fibre polymer material extrusion screw in severe wear and corrosion environment. The screw can be widely used in PE，PC，PA，PS，PMMA, ABS, PVC, PSU, POM, Al-plastics, plastics-wood polymer material injection molding.
