1. Does cold drawn square steel have corresponding reference standards in some basic aspects?
Cold drawn square steel has corresponding reference standards in terms of foundation. The specific reference standard is GB 906-82. In addition, in this standard, the outer shape, size, weight, and deviation of cold drawn square steel are specified.
2. Which of the contact surfaces of cold-drawn square steel and cold-drawn round steel has a strong pressure?
There are many differences between cold drawn square steel and cold drawn round steel. Therefore, they are not the same. Don't confuse them. If the comparison is made from the specific aspect of the contact surface pressure, then the pressure of the cold drawn square steel contact surface is much higher, so the answer to this question is cold drawn square steel.
3. How to improve the toughness of cold drawn square steel?
Want to improve the toughness of cold drawn square steel, effective measures are annealing for recrystallization, used to eliminate the problem of work hardening, and can improve the plasticity and toughness of cold drawn square steel. In addition, the operation is very simple and not complicated.
