Precision cold drawn tube is a high-precision seamless component manufactured by cold drawing processes, renowned for its excellent dimensional accuracy and stable mechanical properties, widely used in various industrial fields requiring strict precision control.

 

It features strict dimensional tolerance (H7 level), surface roughness Ra≤0.4μm, and uniform wall thickness. The cold drawing process enhances its tensile strength, wear resistance and toughness, ensuring stable performance in harsh industrial environments.

 

 

Key processes include blank preparation, precision cold drawing, heat treatment and finish machining. Common materials include 45# steel, 40Cr alloy steel and 304/316L stainless steel, with optional surface treatments for corrosion resistance.

 

 

It is widely applied in hydraulic systems, precision machinery, aerospace and instrumentation, serving as core components for fluid transmission, load-bearing and precision assembly.

 

 

As a high-precision industrial component, precision cold drawn tube meets the strict accuracy requirements of modern industry, providing reliable support for industrial production.
