  Hydraulic Cylinder Rod   Hard Chrome Plating can increase the hardness and service life of piston rod,In the following part ,we’ll take you through the step-by-step hard chrome plating process to give you a better understanding of hydraulic cylinder repair. Step 1: Inspection In the initial inspection, the rod is assessed to evaluate its condition ahead of the chroming process. Step 2: Grinding & Stripping Electrolytic Stripping: During stripping, the rod is placed in a reverse-electrolysis tank. This process is essentially the opposite of electrolytic plating. Whereas chrome plating applies a positive current to a chrome solution – which adheres chrome molecules to the surface of the steel, reverse electrolysis does the opposite. A negative current is applied to the solution and chrome molecules separate from the surface – thereby stripping the old chrome away. Stone Grinding: The other method to remove old chrome is through grinding with large stone grinding wheels. The rod is

 Hydraulic cylinder barrel s endure conditions of extreme pressure. To make them resistant to the extreme conditions under which they operate, the inside diameter of the barrel is honed to a smooth surface finish, ensuring that the barrel is free from ovality and that the bore is parallel. The smooth surface protects the piston seals during operation, extending the effective life of the cylinder. The combination of experienced re-conditioners and high-quality machines, ensure that our clients receive the best reconditioned cylinder rods and barrels to work.Our honed cylinder barrel can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension.

  4140 Quenched & Tempered Chrome Shafting is a kind of steel shafting by Quench & Tempered, Stress Relieved Through Hardened Alloy steel shaft with excellent mechanical properties. 4140 Q&T is a steel in the family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, CrMo, CRMO, CR-MOLY, and similar). They have an excellent strength to weight ratio and are considerably stronger and harder than standard 1020 steel, but are not easily welded (need pre and post weld thermal treatment to avoid cold cracking). While these grades of steel do contain chromium, it is not in great enough quantities to provide the corrosion resistance found in stainless steel. The Quenching process hardens the steel, while the Tempering process restores some of the ductility and removes some of

AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and other applications. Similar to alloy grade AISI 4130 chrome moly alloy steel but with a slightly higher carbon content. The higher carbon content of AISI 4140 steel gives greater strength and heat treatment capabilities in comparison to AISI / ASTM 4130 alloy steels, however it does have inferior weldability characteristics.
