Popular applications are found in dump trucks, lifters, garbage compactors, cranes, agricultural machinery and production equipment with movable parts. Chrome plated bars &amp; rods are mostly used as piston rods (cylinder rods), which is a critical component in hydraulic cylinders and pneumatic cylinders. The basic function of transforming hydraulic power to a linear motion whilst preventing ingress of abrasive media into the hydraulic system will stipulate a set of demands on the rod.<\/p><p>As the chrome plated rod\/ bar is usually used as hydraulic cylinder shafts, pneumatic cylinder shafts and other machine shafts, so they are known as\u00a0<a href=\"https:\/\/skylinepipes.com\/chrome-plate-shafts\/\">Hard Chrome Plated Shafts<\/a>\u00a0also.<\/p><h2><strong>How is chrome plated bar manufactured?<\/strong><\/h2><p><a name=\"how_is_chrome_bar_manufactured\"><\/a><br \/>This product is mostly produced from round carbon steel rods, by using high precision centerless grinding and polishing methods, and then chrome plated to a certain plating thickness such as min. 20 microns (0.0008\u2033), min. 25 microns (0.001&#8243;), min. 50\u03bcm (0.002&#8243;) and so on.<\/p><p><a name=\"main_descriptions\"><\/a><\/p><h2><strong>Main descriptions of Chrome plated bars<\/strong><\/h2><p><img src=\"http:\/\/www.sino-alloy.com\/blog\/wp-content\/uploads\/2022\/06\/060522_0459_Chromeplate1.jpg\" alt=\"\" \/><br \/><a name=\"product_materials\"><\/a><\/p><h3>Product Materials<\/h3><\/div><ul><li><div>SAE 1045:\u00a0<a href=\"https:\/\/skylinepipes.com\/chrome-plated-rod-sae1045\/\">SAE 1045 hard chrome plated bar<\/a><\/div><\/li><li><div>CK45:\u00a0<a href=\"https:\/\/skylinepipes.com\/ck45-chrome-plated-rod\/\">CK45 chrome plated rod<\/a><\/div><\/li><li><div>C45: C45 chrome plated bar<\/div><\/li><li><div>C45E: C45E hard chrome bar<\/div><\/li><li><div>SAE 4140:\u00a0<a href=\"https:\/\/skylinepipes.com\/4140-chrome-plated-rod\/\">4140 chrome plated bars<\/a><\/div><\/li><li><div><p>27SiMn: 27SiMn chrome plated bar<\/p><\/div><\/li><\/ul><div><p><a name=\"product_sizes\"><\/a><\/p><h3>Product Sizes<\/h3><p>Our hard chrome plated shafts \/ bar \/rods are available with sizes as below.<\/p><p>Metric Size: Diameter min. 10 mm, and max. 800 mm\uff1b<\/p><p>Imperial Size: diameter 3\/8&#8243; to 30&#8243;<\/p><p>Length: fixed length 100mm to 13000 mm, random length available.<\/p><p>Tolerance: f7, f8, g6, and so on.<br \/><a name=\"heat_treatment\"><\/a><\/p><h3>Chrome plated bar Heat treatment<\/h3><p>Chrome plated shafts can be supplied with heat treatment condition as below.<\/p><ul><li><div>Induction hardened, high frequency hardening, etc.<\/div><\/li><li><div>Q&amp;T: Quenching and Tempering heat treatment<\/div><\/li><\/ul><\/div><p><a name=\"surface_roughness\"><\/a><\/p><h3>Chrome plated rod Surface Condition<\/h3><p>The surface roughness of the chrome plated bars comes in two series which are Max Ra 0.2 \u03bcm and max Ra 0.4\u03bcm.<br \/><a name=\"chrome_thickness\"><\/a><\/p><h3>Chrome plated Thickness<\/h3><p>The chrome layer thickness of our chrome plated bar is\u00a0Available in Min. 20 microns, 25 microns, 30 microns, &#8230; 50 microns.<\/p><hr \/><p><a name=\"chrome_plated_bar_types\"><\/a><\/p><h2><strong>Main types of Chrome plated rods \/ bars \/ shafts<\/strong><\/h2><p>As one of the leading chrome plated bar manufacturers, our factory produces all types of chrome plated bars \/ rods \/ shafts with full range of materials and a wide size ranges from\u00a0\u230010mm &#8211; \u2300 800 mm.<br \/><a name=\"ck45_chrome-bar\"><\/a><\/p><h3>CK45 chrome plated bar<\/h3><p>CK45 hard chrome plated bar is also called CK45 chrome bar or CK45 chrome rod for short sometimes, it is the\u00a0<a href=\"https:\/\/skylinepipes.com\/chrome-plated-bar-hydraulic-piston-rod\/\">hard chrome plated bar<\/a>\u00a0made of steel grade CK45.<\/p><h4>Product Overview<\/h4><p>Product Name:\u00a0<a href=\"https:\/\/skylinepipes.com\/ck45-chrome-plated-rod\/\">CK45 chrome platd bar<\/a>; CK45 chrome plated rod; CK45 chrome plated shaft.<\/p><p>Origin (factory located):\u00a0China, Wuxi<\/p><p>Brand Name: YOUNGLEE<\/p><p>Size Range<\/p><ul><li><div>Diameter: 6mm to 850 mm<\/div><\/li><li><div>Length: max 18 meters<\/div><\/li><li><div>Imperial sizes and metric sizes both are available<\/div><\/li><\/ul><p>Heat Treatment type:<\/p><ul><li>Q&amp;T (Quenched+Tempered)<\/li><li>Induction hardned (high frequency induction ect)<\/li><li>Q&amp;T + Induction hardened<\/li><li>No heat treated<\/li><\/ul><p>Precision tolerances and surface finish.<\/p><p>Hardness: Rc 60-72<\/p><p>Thickness of chrome plated layer:<\/p><ul><li style=\"list-style-type: none;\"><ul><li><div>Min. 20 microns<\/div><\/li><li><div>Min 25 microns (0.001\u2033)<\/div><\/li><li><div>Min 30 microns<\/div><\/li><li><div>Min 50 microns (0.002\u2033)<\/div><\/li><li><div>Customized<\/div><\/li><\/ul><\/li><\/ul><h4>Material<\/h4><p>Steel grade CK45 is equivalent to SAE standard grade of SAE 1045, so this product is also known as\u00a0<a href=\"https:\/\/skylinepipes.com\/chrome-plated-rod-sae1045\/\">1045 chrome plated rod<\/a>\u00a0or\u00a01045 Chrome Bar.
