Precision E355 Carbon Steel Tube EN10305-2 Standard Cold Drawn Process Thin-Wall Design for Automotive Systems

Manufactured in strict compliance with the EN10305-2 standard, this precision tube utilizes E355 grade carbon steel known for its excellent weldability and high yield strength. Through the cold drawing process, the tube achieves superior dimensional accuracy and a smooth surface finish, while maintaining a thin-wall design to reduce vehicle weight. It is widely used in automotive chassis systems, seat frames, shock absorbers, and stabilizer bars.
