What is the difference between the actual weight and the actual weight of the steel thread?
Is the difference between the work and the theory of weight. General steel factory, have weight difference, unlike canned beverage, not so accurate, this is called "bad" or "inferior". But the mills are not stupid, only under the poor, is not Quejinshaoliang, with a significant difference (such as standard 100KG, he will give you a 110KG).
The actual weight is weighed and weight is calculated according to the theory of diameter *0.00617*M* diameter * * the number of root number general weight were weighed weight greater than you look at this with the giant is even large or small factory of some difference.
As for the calculation of it, big steel mills are GB, generally within 70-80 thousandths of the difference, a little less than 30-40 kilograms of good, bad 80-90 kilograms. Science is the brand superscript weight, the actual weight is weighing several pounds, no difference multiplied by the coefficient, the factory difference is not the same, for example, Xilin Iron and steel will be multiplied by (1-0.06 or 0.07)
