Manufacturing Process and Precision：
The precision drawn steel tubes are processed through the cold drawing process, having undergone multiple drawing deformations, significantly improving dimensional accuracy and surface quality.
Outer diameter tolerance can be controlled within ±0.05mm, with wall thickness uniformity exceeding 98%, superior to hot-rolled tubes.
Mechanical Properties：
High strength and hardnessCold drawing processing generates work-hardening effect, enhancing the yield strength of steel pipes by 15%-20% and achieving tensile strength above 500MPa.
Excellent resilienceThe material grain arranges along the deformation direction, forming a dense fibrous structure, enhancing the axial load-bearing capacity and doubling to tripling the fatigue life.
