The CK45 E355 ST52 carbon cylinder steel tube is a seamless cold-drawn or cold-rolled tube designed for hydraulic and precision mechanical applications. It meets the chemical composition standards of CK45 (DIN 1.1191), E355 (EN 10083), and ST52 (DIN 17100), with typical carbon content between 0.42% and 0.50%, manganese up to 1.60%, and phosphorus below 0.045%. The tubes are produced with tight dimensional tolerances and exhibit a clean, oxide-free surface on both inner and outer walls as specified by the supplier.
These tubes are manufactured without surface defects that cause leakage under pressure or cracking during flaring and flattening. They maintain structural integrity after cold bending, a critical requirement for hydraulic cylinder barrels. The surface brightness and dimensional precision are achieved through cold working processes, not plating or coating. Typical wall thickness ranges from 2mm to 15mm, and outer diameters from 20mm to 150mm, conforming to standard industrial ranges for precision hydraulic tubing.
Buyers in the hydraulic, automotive, and industrial machinery sectors use these tubes for cylinder barrels, piston rods, and high-pressure fluid systems. The tubes are supplied in standard lengths of 5.8m or 6m, packed in bundles with anti-rust paper and wooden crates. Export packaging is standard for sea freight, and delivery terms are typically FOB Yantai or CIF. Minimum order quantities are not stated; buyers should confirm directly with the supplier.

Before placing an order, verify the material certification for each batch, specifically checking the carbon, manganese, and phosphorus content against CK45, E355, and ST52 standards. Request a copy of the mill test report (MTR) and confirm that the surface finish meets your application’s cleanliness requirements. Do not accept tubes with visible rust, scale, or uneven brightness, as these indicate improper processing or storage.
Confirm the Incoterms with the supplier, as delivery terms are typically FOB Yantai or CIF. Lead times for production and shipment are not stated; expect 20 to 40 days for standard orders after confirmation. Packaging must be robust, with anti-rust paper and wooden crates suitable for sea transport. Request a packing list and container loading photos before final payment.
For quality assurance, conduct an independent inspection before shipment, focusing on dimensional accuracy, surface integrity, and pressure test compliance. Use a bore scope to inspect internal cleanliness and a hardness tester to validate surface properties. Request documentation including MTRs, inspection reports, and export certificates. Retain samples from each batch for future reference in case of field failures.
