Question:

Thread steel 20*9 one is 2.001T. How many pieces of this one?

Thread steel 20*9 one is 2.001T. How many pieces of this one?

Answer:

The weight of the thread steel = diameter * diameter *0.00617=20*20*0.00617=22KG, and then the total quality of this piece in the weight of a single thread steel, you can clearly get the number of roots.
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
Thread steel 20*9, one is 2.001T, and this one has about 90. Thread steel 20*9, parameter is 20mm in diameter, length is 9m.
