Automotive Seamless Round Steel
Automotive Seamless Round Steel Tubing , EN10305-1 E215 E235 E355 Carbon Steel
Quick Detail:
Automotive tubes with standard EN10305-1,material E255,delivery condition NBK+black phosphated
1.Precision steel 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.
Description:
Synopsis of Process Routing: Quality Carbon steel — Cold Drawn — Heat Treatment Without Oxidization (NBK Status) — Nondestructive Testing— Flushing The Internal Hole With Special Equipment Under The High Pressure —Dealing With Antirust Oil On Surface — Plastic Capping On Both Ends.
The raw material we choosing:high quality Bao Steel,XingCheng Steel and HuaiSteel.Physical and chemical inspection will be made to make sure each batch is in qualified range. After piecing,each piece of tube is checked to be in permitted size deviation,this can garantee higher thickness tolerance and concentricity.
Production process quality control: We use the domestic first-class drawing machine,the production process is controlled with high hardness alloy internal and external matrix,so the product dimensions tolerance and ovality are strictly controlled in high level.Through the first, middle and last process inspection to ensure product quality.
Inner and Outer Surface Cleaning: We adopt automatic inner surface cleaning machine, rotating brush cleaning and high pressure oil flushing to clean the inner and outer surface.The new steel tube production craftsmanship can effectively remove all particulate attached to the inner and outer surface of tubes and thus achieving the utmost surface cleaness and polishness.
Finished tube anti-rust oil plating: We adopt high pressure spray plating method, the antirust oil is plated by high pressure jet after ten passes of filtering and one pass of precipitation to safeguard the tubes’ outer and inner surface cleaness and polishness.
Applications:
Automotive tubes are used for production of automotive steering systems,clutch system, braking system engine high pressure oil injecting tube,cardan shafts, shock absorbers and air springs, parts of the chassis, axle shafts, construction parts of chassis and axles, steering components, seats construction, bracing for dashboard.
To be used in hydraulic system,automobile and in the occasion where the high precision,brightness,cleanness and mechanical properties of the tube are required.
Specifications:
Automotive Tube diamensions for the automotive industry
Outside diameter ranges from 4 to 60 mm and wall thickness ranges from 0.5 to 7mm.
