WHAT MATERIAL IS USED FOR THE CYLINDER BARREL?

图片
  As the main component of the hydraulic cylinder, the processing quality of the   cylinder barrel  directly affects the life and reliability of the entire product. The cylinder has high processing requirements, and its inner surface roughness is required to be Ra0.4 ~ 0.8um, and the requirements for coaxiality and wear resistance are strict. Generally, it is processed and produced by the principle of  honing  or rolling. The common materials of cylinder barrel are SAE1020, 1026, 1045,  ST52 seamless honed tubes , the steel tube is honed or rolled to meet the roughness requirement within 0.4μm. The low-pressure oil cylinder can use 1020 steel pipe, and the high-pressure oil cylinder can use CK45 steel pipe. As a professional cylinder barrel supplier, manufacturer,exporter in China,  Wuxi YUTONG  has more than 20 years production experience, we sell hydraulic honed tubing to customers and provide full range of technical support. Imperial sizes...

CYLINDER ROD HARD CHROME PLATING AND GRINDING

  Cylinder rod is a very important part for hydraulic cylinder, Wuxi YUTONG as a professional manufacturer of cylinder piston rod, we will have many steps to guarantee the quality of the rod, like  Inspection，grinding & peeling,cleaning & masking, and then hard chrome plating . Hard chrome plating, and then OD grinding is an excellent answer for repairing and/or providing wear resistance to parts such as cylinder shafts , rolls, hydraulic cylinders, rams, pistons and rods.   It is used in everything from plating jewellery with gold to applying reflective metal plating to satellites and spacecraft. In this process, objects to be plated are placed in a bath containing a solution of dissolved metal molecules (in our case this metal is a special Chromium formulation). Electrodes are attached to the object to be plated and a positive current is applied to the solution. As the current runs through the solution and out through the electrodes, it causes the dissol...

WHAT IS THE TENSILE STRENGTH OF 4140 CHROME PLATED STEEL BAR?

  4140 chrome plated steel bar   is made of 4140 round steel bar which has achieved high hardness and corrosion resistance through heat treatment and hard chrome plating . 4140 also named 42CrMo4, It is a chromium and molybdenum alloy steel that has an excellent weight to strength ratio. It is considerably stronger than standard steel. Although it is chromium steel and often referred to as “chromoly steel” it does not contain as much chromium as stainless steel. Therefore the corrosion resistant is improved compared to standard steel but not to the same degree as stainless steels. The purpose of the molybdenum is to add uniformity of hardness and strength to this alloy. 4140 responds readily to heat treatment and is relatively easy to machine in the heat treated condition. It has a tensile strength of 150,000 psi, yield strength of 130,000 psi and approximately 35-45% elongation. This metal is typically used for bolts couplings, axle shafts,  cylinder piston rods , tracto...
