Why Choose Our 4140 Honed Cylinder Tubes?​

 4140 honed cylinder tubes are ​high-strength, precision-finished steel tubes​ widely used in ​hydraulic cylinders, industrial machinery, and heavy-duty equipment. Made from ​chromium-molybdenum alloy steel (AISI 4140)​, these tubes undergo ​precision honing​ to achieve an ultra-smooth internal surface, ensuring ​optimal sealing, reduced friction, and extended service life.

YUTONG INDUSTRY ,specialize in manufacturing ​4140 honed tubes​ with ​strict quality control, advanced processing techniques, and industry-leading expertise. Our products meet ​ASTM, DIN, and ISO standards, making them ideal for ​high-pressure hydraulic systems, oil & gas equipment, and mobile hydraulics.

Key Advantages of 4140 Honed Cylinder Tubes​

​1. Superior Material Properties (AISI 4140 Alloy Steel)​​

✔ ​High Tensile Strength (850-1000 MPa)​​ – Withstands extreme pressure in hydraulic systems
✔ ​Excellent Toughness & Fatigue Resistance​ – Ideal for dynamic, high-load applications
✔ ​Good Machinability & Weldability​ – Easier to fabricate than high-carbon steels
✔ ​Heat Treatable (Quenched & Tempered)​​ – Enhances hardness (HRC 28-32) and durability

​2. Precision Honing Process for Optimal Performance​

Our ​4140 honed tubes​ undergo ​multi-stage honing​ to achieve:
✔ ​Ultra-Smooth Surface Finish (Ra 0.2-0.4 µm)​​ – Minimizes wear on seals & pistons
✔ ​Tight Dimensional Accuracy (±0.02mm)​​ – Ensures perfect fit with hydraulic components
✔ ​Improved Straightness (≤0.1mm/m)​​ – Reduces friction and uneven wear

​3. Corrosion & Wear Resistance​

✔ ​Optional Chrome Plating (20-50µm)​​ – For enhanced corrosion resistance in harsh environments
✔ ​Phosphating or Nitriding Treatments​ – Improves surface hardness and longevity



Why Choose Our 4140 Honed Cylinder Tubes?​​

✅ ​High-Strength Material (AISI 4140)​​ – Superior to standard carbon steel tubes

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.

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...

The Hardness Of Ck45 induction hardened Chrome Rod

  Induction hardening  is a non-contact process used for the surface hardening of steel and other alloys. The parts to be treated are placed inside a copper coil and heated above their transformation temperature by applying an alternating current to the coil. The   cylinder rod   is then quenched to retain the enhanced properties of the steel alloy. During this process, the   induction hardened chrome rod   core remains unaffected and its physical properties remain the same. CK45 is a medium tensile carbon steel supplied in the turned, induction hardened and straightened, precision ground, polished, chrome plated and final polished condition, with a typical base metal tensile strength of 670 Mpa, an induction hardened case of 3.2mm thick approx. to Rc55-65, plus a typical hard chrome plated surface hardness of HV 1000 - 1150.Characterised by an extremely smooth surface finish with excellent wear and corrosion resistance, supported by an induction harde...
