The process of creating CDS tubing involves cold drawing seamless steel tubes through a die, which results in tight dimensional tolerances, a superior surface finish, and increased strength. Typically, this tubing boasts high tensile strength ranging from 500 to 700 MPa and yield strength of about 350 to 550 MPa, depending on the material grade. This method refines the grain structure, enhances mechanical performance, and ensures uniformity throughout the tube’s cross-section. Plus, CDS tubes are easy to machine and weld, making them perfect for applications that demand precise fits, high strength, and clean finishes.
