Product Description
DIN 2391 Precision Seamless Steel Tube
St35, ST45, ST52, NBK / GBK / CW / SR
1. Basic Specifications
- Standard: DIN 2391 (German Industrial Standard for cold-drawn precision seamless steel tubes)1.
- Material: Carbon steel (e.g., ST52 grade)8, suitable for mechanical and hydraulic applications6.
- Surface Treatment: Options include phosphating (anti-corrosion treatment)4 and honed/bright surfaces (improved smoothness)
2. Manufacturing Process
- Cold Drawing: Precision cold-drawn process ensures dimensional accuracy and mechanical strength
- Honing: Post-processing to achieve ultra-smooth internal surfaces for hydraulic systems
3. Dimensions & Tolerances
- Outer Diameter (OD): 6-168mm
- Wall Thickness: Tolerance within ±8% of specified thickness
- Length: 5.8M / 6M / 11.8M , random length 5-5.8M
4. Mechanical Properties
- High-pressure resistance and excellent load-bearing capacity
- Optimized for applications requiring tight tolerances and structural integrity
5. Key Features
- High Precision: Tight dimensional tolerances for seamless integration in complex assemblies
- Surface Quality: Bright or honed surfaces reduce friction and enhance cleanliness in hydraulic/pneumatic systems
- Durability: Enhanced strength from cold-working processes
6. Applications
- Hydraulic/Pneumatic Systems: Cylinder tubing and pipelines
- Automotive: Precision components requiring high dimensional stability
- Heavy Machinery: Structural parts in mechanical engineering
