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...

The Advantages Of E355 ST52 Honed Tubes

  E355 ST52 Honed tube  is very widely used as cylinder barrel in hydraulic cylinder design and repair. It is the core part of the hydraulic cylinder.  Honing is a processing technique. Through the honing head, the reciprocating high-speed grinding technology is used to process the inner hole of the cold drawn pipe, so that the inner hole meets the requirements of the tolerance size and surface roughness we need. The advantages of our ST52 honed tubes 1. High precision tolerances;  Wuxi YUTONG ’s honed tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension. 2. Seamless tube with high pressure resistance;We only use  seamless cold drawn tubes  to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications. 3.   Advanced manufacturing equipment and facilities, including: cold drawing machine, cold roll...

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...
