Injection molding machine screw barrel material
Manufacturing cartridges, the current domestic commonly used materials are 45,40Cr and 38CrMoAIA. The material used to make the barrel in the imported extruder is commonly used in alloy steel 34CrAINi and CrMoV9. The yield strength of this material is about 900 MPa. After nitriding treatment, hardness above 1000HV, both wear and good corrosion resistance. Tungsten carbide alloy barrel, tungsten carbide alloy + chromium alloy barrel, tungsten carbide alloy + chrome alloy + nickel alloy barrel, just use Material quality alloy just for the substrate, the inner hole casting the above alloy, improve the barrel wear resistance, Corrosion resistance. |
