It is commonly used in hydraulic cylinders, where it serves as the main rod that extends and retracts to provide linear motion. The chrome plating on the rod provides several benefits, including increased corrosion resistance, improved wear resistance, and reduced friction. This makes the chrome cylinder rod ideal for use in demanding environments where the rod may be exposed to moisture, chemicals, or abrasive materials. Popular applications are found in dump trucks, lifters, garbage compactors, cranes, agricultural machinery and production equipment with movable parts.<\/p><h2><strong>How is chrome cylinder rod manufactured?<\/strong><\/h2><p><a name=\"how_is_chrome_rod_manufactured\"><\/a><br \/>The production of chrome cylinder rod primarily involves utilizing round steel rods, which undergo meticulous centerless grinding and polishing techniques. Following this, the rods are subjected to chrome plating, ensuring a minimum plating thickness of 20 microns (0.0008\u2033), 25 microns (0.001&#8243;), 50\u03bcm (0.002&#8243;), and other specified measurements upon customers&#8217; requests.<\/p><p><a name=\"chrome_rod_descriptions\"><\/a><\/p><h2><strong>Product descriptions: Chrome Cylinder Rod<\/strong><\/h2><p><img src=\"http:\/\/www.sino-alloy.com\/blog\/wp-content\/uploads\/2022\/06\/060522_0459_Chromeplate1.jpg\" alt=\"\" \/><br \/><a name=\"chrome_rod_materials\"><\/a><\/p><h3>Materials (steel grades)<\/h3><\/div><ul><li><div>CK45:\u00a0<a href=\"#ck45_chrome_rod\">CK45 chrome cylinder rod<\/a><\/div><\/li><li><div>C45: C45 chrome plated cylinder bar<\/div><\/li><li><div>C45E: C45E hard chrome cylinder bar<\/div><\/li><li>Steel 1045: <a href=\"#sae1045_chrome_rod\">SAE 1045 hard chrome plated cylinder rod<\/a><\/li><li><div>Steel 4140: <a href=\"#sae4140_chrome_rod\">4140 chrome plated rod<\/a><\/div><\/li><li><div><p>20MnV6: 20MnV6 chrome plated rod<\/p><\/div><\/li><\/ul><div><p><a name=\"chrome_cylinder_rod_sizes\"><\/a><\/p><h3>Chrome Cylinder Rod Sizes<\/h3><p>Younglee manufactures &amp; supplies chrome plate rods for cylinders with size ranges as below.<\/p><p>Metric Size: Diameter min. 6 mm, and max. 800 mm.<\/p><p>Imperial Size: diameter 1\/4&#8243; to 30&#8243;<\/p><p>Length: from 100mm to 13000 mm, we can make the chrome rods cut to length.<\/p><p>Diameter Tolerance: ISO 286-2 \/ f7 \/f8 \/g6, and so on.<br \/><a name=\"heat_treatment\"><\/a><\/p><h3>Chrome cylinder rod Heat treatment<\/h3><p>Chrome plated cylinder rod can be supplied with heat treatment condition as below.<\/p><ul><li><div>Induction hardened: also known as high frequency hardening;<\/div><\/li><li><div>Q&amp;T: Quenching and Tempering heat treatment<\/div><\/li><li>No heat treated is also available as per customers&#8217; requests, this usually is in the consideration of costs or some special purpose.<\/li><\/ul><\/div><p><a name=\"surface_roughness\"><\/a><\/p><h3>Surface Quality<\/h3><p>The chrome plated bar for cylinders should be with a super smooth and bright surface, without any defects such as scratches, dents, nicks and so on.
