Import Cold Rolled Precision Steel Tubes For Gas Spring — Buy in Bulk from Supplier in China

The product is a cold rolled precision steel tube designed for gas spring applications. It conforms to DIN2391, EN10305‑1, ASTM A179, ASTM A192 and ASTM A519 standards. Available material grades include SAE 1010, SAE 1020, carbon steel grades #10, #20, #45 as well as stainless steels 304 and 316. Outer diameters range from 8 mm to 50 mm, wall thicknesses from 0.5 mm up to 50 mm, and lengths are offered between 3 m and 12 m, either fixed or cut to custom sizes.

The tubes are produced by high‑precision cold drawing and cold rolling, followed by heat treatments such as BK, BKS or NBK to achieve dimensional stability. Typical tensile strength for SAE 1010 is around 350 MPa and for SAE 1020 about 450 MPa, while stainless grades 304/316 reach roughly 520 MPa, providing the mechanical performance required in load‑bearing springs. Surface roughness commonly falls within Ra 0.2 µm, meeting the smoothness needed for seal‑compatible assemblies. These characteristics align with standard industry expectations for gas‑spring tubing.

Importers usually request the tubes in coils or straight lengths, packed in timber crates or steel pallets to protect the surface during transit. Trade terms often involve FOB or CIF incoterms, with payment via T/T or L/C after sample approval. Buyers such as automotive suspension manufacturers, machinery equipment makers and OEMs of hydraulic systems typically source these tubes for their reliability and compliance with international standards.
