The Key Technical Advantages Of DIN 2391/C Hydraulic Steel Tube

 In high-pressure hydraulic systems, every component must deliver uncompromising reliability. At the heart of these systems lies a critical element: the DIN 2391/C hydraulic steel tube with high pressure DIN 2391/C seamless precision steel tubes are engineered to meet the rigorous demands of industrial hydraulics, offering superior strength, durability, and precision. As a trusted manufacturer of DIN 2391/C hydraulic steel tubes, YUTONG INDUSTRY combines advanced production expertise with stringent quality controls to provide solutions that empower your operations.

Our DIN 2391/C hydraulic tubes are crafted through a meticulously controlled production process to ensure consistency and performance:

1. Material Selection：High-grade cold-rolled steel billets are sourced to guarantee chemical composition (e.g., St52, St37) compliance with DIN 2391/C standards.

2. Cold Drawing & Precision Sizing: Tubes undergo a multi-stage cold-drawing process to achieve tight dimensional tolerances (outer diameter ±0.3 mm, wall thickness ±5%). Proprietary die technology ensures smooth internal surfaces (Ra ≤ 0.4 µm), minimizing friction and pressure loss in hydraulic circuits.

3. Stress-Relieving Heat Treatment：A controlled annealing process eliminates residual stresses from cold working, enhancing structural integrity and fatigue resistance.

4. Surface Finishing & Protection：Phosphating or oiling options provide corrosion resistance, extending service life even in harsh environments.

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...

The Hardness Of 4140 Chrome Cylinder Rod

图片
  4140 chrome cylinder rod   is used extensively by the hydraulic cylinder and pneumatic industries, and is employed by other industry sectors for a wide range of applications requiring higher strength. 4140 is a 1% Chromium - Molybdenum high tensile steel supplied in the hardened and tempered, cold drawn or turned, precision ground, polished, chrome plated and final polished condition, with a typical base metal tensile strength of 850 - 1000 Mpa, plus a typical  hard chrome plated surface hardness  of HV 1000 - 1150. Characterized by an extremely smooth surface finish with excellent wear and corrosion resistance, coupled with a base material giving high strength and good impact properties. 4140  hard chrome plated bar  has very good machinability, similar to 4140 uncoated bar. Machining however should commence beneath the chrome plating, or at the unchromed surface at the end of the bar. To protect the polished chrome surface, soft materials such as copper...
