F2200HL/F1600HL/F1600/F1300/F1000/F800F500 dual metal cylinder under strict quality control, hardening and heat treatment, hardness of 60HRC, internal set of high finish, wear resistance, corrosion resistance, long service life. The chrome plated cylinder liner is made of high quality forged steel and chrome plated inside hole, with a hardness of 58-62 HRC. The bimetal sleeve combines the advantages of a forged wear resistant jacket and a high chromium wear resistant corrosion resistant sleeve. The outer coat is centrifugal forging, and the high chromium inner sleeve heat treatment has reached 62 Rockwell C grade. The production of the bimetallic cylinder is strictly controlled, the size is within the tolerance range, and the installation is simple, the inner sleeve has the advantages of high finish, wear resistance, corrosion resistance and long service life, and is suitable for various abominable working conditions
