Our company is famous for manufacturing bright high-precision seamless steel tubes for transmission of fluids for years, it is one of the main products by our company. This type of products is subject to DIN standard, and equipped with strict quality assurance system and enterprise inner-control dimension standards, so as to make sure that the quality can be satisfied by clients.

Specifications of Precision Carbon Steel Tube:
1. Diameter: 4mm~60mm
2. Length: 3m, 6m, 9m or customized
3. Thickness: 0.5mm~8mm
4.Standard: DIN2391, DIN17175, EN10305, ISO8535, GB/T8713, GB/T8163, etc.
5. SAE1010, SAE1020, ST35, ST37.4, ST52.4, etc.

Surface roughness 

High Precision Steel Tube is drawn by mandrel and oil of each process so that the outer and inner surface is very smooth without any burr. Normalizing process makes the surface more shinning like mirror. Surface roughness can be controlled within Ra 0.2. No oxidized residual substances enable the hydraulic fluid and pneumatic gas go through the tube fluently.

Concentricity and straightness 

Strong wear resistance, High concentricity and Good straightness

We can control Straightness within 0.5/1000 which makes tubes easy for processing, machining and improve the processing efficiency and quality of finished products.

Packaging of Precision Carbon Steel Tube :

Shanghai Metal Corporation Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information. 

Application of High Precision Steel Tube

1.    Hydraulic system

2.    Automobile

3.    Compression ignition engine

4.    Nested Card connector

5.    Construction machine vehicles.

Mechanical Properties 

The tube can be bent at any figure and bear the impact of high pressure, cold bending, flaring and flattening without any crack and breaks. The tube is with good elongation and tensile strength so different machining process can be arranged without special treatment.

Usage: Automotive industry, hydraulic system and other machine parts for high standard surface and mechanical properties.
