Manufacturing barrels,the current domestic commonly used materials are 45,40Cr and 38CrMoAIA. Imported extruder in the barrel of the manufacturing materials, commonly used alloy steel 34CrAINi and CrMoV9.The yield strength of this material is about 900MPa. After nitriding treatment,the hardness of 1000HV or more,both wear-resistant and good corrosion resistance. Tungsten carbide alloy+nickel alloy cylinder,the use of Material High quality alloy just as the substrate,the hole casting the alloy, to improve the wear resistance of the barrel,Corrosion resistance.
