 Hard chrome plating, also known as hard chromed , is a technique of electroplating that applies a thin layer of chromium onto a cylinder piston rod . Chrome plating is used to provide a working surface that requires one or more of the following characteristics: to reduce friction, resist abrasion, or increase corrosion resistance. It is very hard, measuring between 66 to 70 HRC.  Surface defects and roughness are amplified because hard chrome does not have a leveling effect. Friction between a Anbao cylinder rod and its seals, and the resulting wear, has a crucial influence on the efficiency and service life of a hydraulic cylinder . Chrome plating is a cost-effective repair option that can allow salvage of a cylinder rod, cylinder tube , or valve spool instead of replacing it with new. In addition to the cost benefits, chrome plating also creates a hardened wear surface, extending the life of most high wear areas resulting in longer run times between repair or replacement of cylind

  GOST 1050 Grade 20 Carbon Steel Seamless Tubes   are also known as mild steel pipes and tubes. GOST 1050 Grade 20 Tubes are low-cost Low Carbon Steel Tubes with 017-024 % carbon content with combination of 035-065 % manganese easy to form and shape .These pipes are manufactured as per GOST Specification and commercially referred as cs pipes or ms pipes.Low Carbon Seamless Steel Pipes or   pre-honed tubes   are not as hard as hig carbon steel pipes,Though carburizing can increase its surface hardness.

  Standard seamless precision tubes are produced using the cold drawn process. Seamless precision tubes can be supplied as cut tubes and bent tubes. Cut tubes are designed especially for manufacturers of automotive components. Seamless precision steel tubes from our production satisfy the requirements for the following applications: components for the vehicle drivetrain, cars suspension systems, fuel injection, components for engine and transmission, components for body and chassis, vehicle control systems and others. Stress relieving is carried out on seamless cold drawn tubes in order to minimise residual stresses in the structure thereby reducing the risk of dimensional changes during further manufacturing or final use of the component.stress relieving does not change the hydraulic tube ’s structure and does not significantly affect its hardness. Hardened and tempered steel tube to be stress relieved must be treated at a temperature around 50°C below the temperature used for
