20#Seamless Cold Drawn Steel Tube

High precision: Cold drawn seamless steel pipes have high dimensional accuracy and straightness, which can meet the needs of high-precision mechanical parts. This high precision not only improves the processing efficiency of the product, but also reduces the scrap rate and increases the material utilization rate.

High strength: The cold drawing process causes significant plastic deformation during the processing of steel pipes, thereby improving their strength and hardness. This high strength enables cold drawn seamless steel pipes to withstand higher pressures and loads.
