ST35 , ST37.4 Carbon Steel Hydraulic Tubing For Nested Card Connector , Pipe Joints

Quick Detail:

1.Precision seamless tubes for automotive industry are made using the cold drawing process. Precision tubes are made from carbon steel from quality Bao Steel,XingCheng Steel,and HuaiSteel.

2. The tubes are high precision in tolerance,excellent surface brightness,no oxidization on the outer and inner walls after heat treatment,high cleanness of inside wall.

3. No deformation after cold bending,no crack after flaring and flattening.

4.Stable work pressure for hydraulic system.

Description:

The steel grades of raw material used in our company are mainly ST35, ST37.4(10#), ST45 (20#), ST55 (35#), Ck45 (45#), ST52.4 (16Mn) etc. produced by Shanghai Baosteel Group.

The antirust oil is absorbed by means of the micro pore on the film to prevent from the rust. The caps are covered at two ends of tube to prevent from the dust.

Main Features: color of steel tube: bright black. Color is homogeneously distributed on the tube surface. The tube has good property of antirust.

Applications:

Used in hydraulic system,including automotive Hydraulic power steering system, the clutch system, braking system, engine high pressure oil pipe, excavator hydraulic oil pipe,nested card connector (pipe joints) with matching,shippment industry.
