Cold drawn steel pipe is produced by drawing hot - rolled or cold - rolled seamless steel pipes through a die at room temperature.
It features extremely precise dimensions with very strict control over outer diameter, inner diameter, and wall thickness. The surface quality is superior, with high smoothness and minimal surface defects. The cold drawing process enhances the mechanical properties, giving it high tensile strength, yield strength, and toughness. It can be made into pipes with complex cross - sectional shapes and very small diameters, which is difficult for other processes.

We offer a wide range of high-quality seamless steel pipes made from various materials such as 10#, 45#, and more. Available in hot rolled, cold rolled, and cold drawn specifications, our pipes are suitable for fluid, boiler, gas, and oil applications.

American standard ASME/AISI/ASTM standard 4140 alloy seamless steel pipe is the core material in the fields of machinery manufacturing, petrochemical industry, automobile industry, etc., with high strength, wear resistance and corrosion resistance. As a medium carbon chromium-molybdenum alloy structural steel, 4140 achieves excellent comprehensive performance through quenching and tempering heat treatment, and is widely used in high-pressure pipelines, mechanical parts and oil drilling equipment.
Alloy composition: Contains 0.38-0.43% carbon (C), 0.75-1.00% manganese (Mn), 0.80-1.10% chromium (Cr) and 0.15-0.25% molybdenum (Mo). The grain structure is optimized through microalloying technology to improve hardenability and fatigue resistance.
