Cold rolling: using hot-rolled steel coil as raw material, after pickling to remove oxide scale, cold rolling is carried out, and the finished product is hard-rolled coil. The plastic index decreases, so the stamping performance will deteriorate, and it can only be used for parts with simple deformation.
Hard-rolled coils can be used as raw materials for hot-dip galvanizing plants, because hot-dip galvanizing units are equipped with annealing lines. The weight of the rolled hard coil is generally 6~13.5 tons, and the hot-rolled pickled coil is continuously rolled at room temperature. The inner diameter is 610mm.

Note:
a) The tensile test takes the transverse pattern; the pattern width b is 25mm, and the pattern gauge length L0 is 50mm.
b) When there is no obvious yield point, Rel can be replaced by Rp0.2; when the product thickness is less than 0.70mm and ≥0.50mm, the upper limit of yield strength can be increased by 20N/mm2, and when the thickness is less than 0.50mm, it can be increased by 40N/mm2 ;
c) When the product thickness is >1.50mm and ≤2.0mm, the value of r90 or r is allowed to decrease by 0.1 (absolute value); when the thickness is >2.0mm, the value of r90 or r is allowed to decrease by 0.2 (absolute value);
d) The values of r90 and n90 or r and n are only applicable to products with thickness ≥0.50mm; r=(r0+ r45+ r90)/4,
n=(n0+n45+n90)/4.
