In order to improve the performance of stainless steel pipe (ss pipe), it is often necessary to adopt certain cold working methods, such as cold drawing, cold rolling, cold rolling, cold bending, cold expansion, cold twisting, etc., which can achieve a certain effect, but also cause a certain amount of damage. Cold working is actually like welding, which will inevitably damage the performance of stainless steel pipes, especially the corrosion resistance or heat resistance.
