A cold drawn tube is a seamless steel tube produced using cold drawing technology, which provides moderate precision and mechanical properties. However, its inner surface finish is relatively rough and often requires further processing for high-precision applications.
Cold drawing involves pulling the steel tube through a die at room temperature to refine its outer diameter and wall thickness.
Annealing process is used to relieve internal stress and improve mechanical properties.
✅ High Strength – Cold working increases hardness and load-bearing capacity.
✅ Moderate Dimensional Accuracy – Tolerance level is typically H10-H11, lower than honed tubes.
✅ Rough Inner Surface – Requires additional processing (honing or roller burnishing) to achieve a smooth finish.
✔ Automotive parts (drive shafts, shock absorbers, etc.)
✔ Fluid and gas transmission pipelines
✔ Structural components for machinery
