CK20 Precision Cold Drawn Seamless Steel
CK20 Precision Cold Drawn Seamless Steel from Wuxi Longwei Precision Tube Co., Ltd. is manufactured to DIN 2391 and EN 10305 standards, delivering tight dimensional tolerances and a smooth inner surface finish. The material is Carbon Steel CK20, a low-carbon grade with good weldability and machinability, supplied as cold drawn tubes for applications requiring precision and consistency. These tubes are typically used in hydraulic systems, automotive components, and instrumentation where surface quality and dimensional accuracy are critical.
The cold drawing process enhances the mechanical properties of CK20, producing a fine-grained microstructure with improved tensile strength and hardness compared to hot-rolled alternatives. Standard surface finishes for this grade include bright or oiled, with typical roughness values of Ra 0.4 to 0.8 micrometres. Cold drawn seamless tubes in this category are commonly produced in outer diameters ranging from 6 mm to 219 mm, with wall thicknesses from 1 mm to 30 mm, though exact dimensions depend on the supplier’s capabilities.
Industries such as automotive manufacturing, machinery production, and fluid power systems rely on CK20 seamless tubes for their balance of strength, ductility, and ease of fabrication. Buyers typically source these tubes in bundles or straight lengths, with packaging tailored to protect against corrosion during transit. For bulk orders, confirm the supplier’s ability to meet specific length tolerances and straightness requirements, as these directly impact downstream processing and assembly.

Sourcing CK20 Precision Cold Drawn Seamless Steel from Wuxi Longwei Precision Tube Co., Ltd. - China Import Guide
Before ordering CK20 Precision Cold Drawn Seamless Steel from Wuxi Longwei Precision Tube Co., Ltd., verify the supplier’s ability to meet your exact dimensional and mechanical property requirements. Request mill test certificates (MTCs) or material certifications to confirm compliance with DIN 2391 and EN 10305 standards, as these documents provide traceability and assurance of quality.
Confirm the logistics details, including packaging, lead times, and Incoterms. CK20 tubes are typically supplied in bundled or straight lengths, so discuss packaging options to prevent damage during transit. Clarify whether the supplier can accommodate FOB, CFR, or CIF terms, and agree on payment methods such as T/T or L/C to secure the transaction.
Quality checks should include visual inspection for surface defects, dimensional verification using calipers or micrometres, and mechanical testing for tensile strength and hardness. Request a pre-shipment inspection report to ensure the tubes meet your specifications. Additionally, confirm whether the supplier provides third-party inspection services or can facilitate testing by an independent laboratory.
