About Qiyu

All kinds of screw barrels produced by our company are made of 38CrMOALA alloy steel. After quenching and tempering, finishing, and surface ammoniation treatment, they can also be electroplated (hard chromium plated on the surface), and the screw surface is sprayed with double alloy. The barrel surface uses the advanced production process of bimetallic technology, the centrifugal casting method, so that the products have high wear resistance, corrosion resistance, improve life and other advantages, and can replace imported products.
