Cold drawn square steel As for the reduction of the press, it depends on the actual situation and past experience. At the same time, when pressing, you can also know the amount of depression and rebound by the instrument, so that you have a good idea. Cold drawn square steel is one of the cold drawn sections. The learning work of cold drawn square steel will be carried out, mainly to master its related knowledge content. In this way, you can also expand your professional knowledge and obtain good results in the use of cold drawn square steel. It refers to a cold-drawn steel with a square forged shape, and cold-drawn square steel is from a professional perspective. It belongs to cold drawn steel. The bending of this kind of square steel can be improved by recrystallization annealing to improve the toughness. Then, the bending machine is used to perform the bending work. After that, the problem of work hardening is eliminated for recrystallization annealing, and at the same time, the plasticity and toughness of the material are restored.
