Injection molding machine screw cylinder barrel Material
Manufacturing barrel,the current commonly used materials are 45,40Cr and 38CrMoAIA.Imported extruder barrel manufacturing materials,commonly steel 34CrAINi and CrMoV9.This material has a yield strength of about 900MPa.After nitriding treatment,hardness 1000HV above,both wear and good corrosion resistance.Tungsten alloy cylinder,tungsten carbide+chromium alloy cylinder,tungsten carbide+chromium alloy+nickel alloy barrel Material selection of high quality alloy steel for the substrate,the hole above casting alloy,barrel increase wear resistance,corrosion resistance.
