Principle Of Cold-drawn Hexagonal Steel

The principle of cold-drawn hexagonal steel is to apply tensile stress exceeding the yield point of the steel bar at room temperature to make the steel bar produce plastic deformation, thereby achieving the purpose of increasing the yield strength of the steel bar and saving steel. The specific process is as follows:

Process steps: The cold drawing process includes raw material selection, pre-treatment (such as pickling and cutting), stretching, finishing and improvement. During the stretching process, the stretching force and stretching speed need to be strictly controlled to ensure uniform deformation and dimensional accuracy of the steel.
