Precision cold drawn pipe has the characteristics of high precision, high finish, good inner wall cleanliness, high pressure without leakage, cold bending without deformation, flaring, flattening without cracks, etc. It can be used for various complex deformation and mechanical processing. The chemical composition of precision cold drawn pipe is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.

Main uses: for automobiles, motorcycles, refrigeration equipment, hydraulic parts, bearings, pneumatic cylinders, and other customers who have high requirements for steel pipe accuracy, smoothness, cleanliness, and mechanical properties.

What happens in precision cold drawn tubing is work hardening. During the cold drawing process, the metal undergoes plastic deformation. There are many slip systems in a crystal where dislocation motions intercept each other. Many dislocations are pinned, causing dislocations to pile up and the source of dislocations to stop. These processes lead to a decrease in dislocation mobility and an increase in dislocation density. When further plastic deformation occurs, the stress increases enough that the pinning dislocations start to move, the pinning dislocations cross-slip, and the edge dislocations cannot cross-slip. Therefore, dislocation intersection occurs and the fixed order increases.

Cold drawn is a processing technology of materials. For metal materials, cold drawn refers to drawing at room temperature in order to achieve a certain shape and certain mechanical properties. Cold drawn products have the advantages of high dimensional accuracy and good surface finish compared to hot forming.
