Carbon Steel Tube For Car Tubes DIN1630 ST37.4 , Precision Seamless Tubes

Carbon Steel Tube For Car Tubes DIN1630 ST37.4 , Precision Seamless Tubes

Specifications:

Size:OD4mm-60mm,TH0.5mm-7mm

Standard:DIN1630

Material: ST37.4,ST44.4,ST52.4

Delivery State:NBK

Description:

1.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.

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.

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.

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.

Testing of precision tubes for carbon Precision steel tube

chemical analysis, tensile test, water pressure test, flattening test or drift expanding test,dimensional inspection and visual inspection.

Applications:

Precision tubes are used in hydraulic system,automobile,mechanical parts and in the occasion where the high precision,brightness,cleanness and mechanical properties of the tube are required.
