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 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...

MANUFACTURING PROCESS OF PRECISION COLD DRAWN TUBES

  Precision cold drawn tube   is the carbon, alloy or stainless steel pipe with high precision sizes. Usually it has been made through hot rolling or cold drawn (cold rolling) processes. So precision pipe is a kind of seamless pipe.International standard for precision pipe is   DIN 2391 , which is applied with European standard.As a matter of fact, more steel pipe standard could applied for the precision pipe. Includes DIN2445, EN10305, DIN1630, DIN1629, ASTM A106, ASTM A179, JIS G3445Materials available with 10#, 20#, 35, 45, 40Cr, 25Mn. 37Mn5, St35(E235), St37.4, St45(E255),  St52(E355 ) and etc. For hot rolling precision steel pipe, tolerance of OD is +/- 0.1%.For  cold drawn precision tubes , tolerance allowed in below conditions: Diameters 6mm to 10mm, normal tolerance condition +/- 0.2%, premium tolerance condition +/- 0.15%. 10mm to 30mm, normal tolerance condition +/- 0.4%, premium tolerance condition +/- 0.2%. 30mm to 50mm, normal tolerance condition +/...
