Features of cold-rolled steel coil :
1, cold rolled steel coil thickness more accurate, smooth surface, beautiful, but also has superior mechanical properties, especially machining performance.
2. The maximum thickness of cold-rolled steel coil is less than 0.1-- 8.0mm, such as the thickness of cold-rolled steel coil in most factories is less than 4.5mm;The minimum thickness and width are determined according to the equipment capacity and market demand of each plant.
3, cold rolled steel mill power, low rolling efficiency, and the rolling process in order to eliminate the work hardening have to carry out intermediate annealing, so the cost is higher, but cold rolled steel surface bright, good quality, can be used to process finished products, cold rolled steel is widely used.

|Q215 Carbon Steel Coil||Uniform Number Code||Grade||Deoxygenation Method||C||Si||Mn||P||S|
The uniform numbers of killed steel and special killed steel grades are shown in the table, and the unified numerical codes of boiling steel grades are as follows:
Q215AF--U12150 , Q215BF--U12153 .
|Grade||Yield Strength ReH/(N/mm2)|
Elongation after break A/%
|Impact test (V-notch)|
|Thickness (or diameter)/mm||Thickness (or diameter)/mm||temperature/℃|
Impact absorption energy (longitudinal)/J
|b For steel with a thickness greater than 100mm, the lower limit of tensile strength is allowed to be reduced by 20N/mm2. The upper limit of tensile strength of wide-band steel (including shear steel plate) is not a delivery condition.|
Q215 Carbon Steel Coil
|Specimen Direction||Cold bending test 180° B=2αa|
|Steel thickness (or diameter)b / mm|
|Center diameter d|
|a B is the width of the sample, and α is the thickness (or diameter) of the sample.|
b When the thickness (or diameter) of the steel is greater than 100mm, the bending test shall be determined through negotiation between the two parties.
Q215 cold rolled carbon steel coil has high plasticity, toughness and welding performance. Q215 carbon steel coil also has good stamping performance, but its strength is low.
Q215 cold rolled carbon steel coils are mainly used to manufacture anchor bolts, ploughshares, chimneys, roof panels, rivets, low-carbon steel wires, thin plates, welded pipes, tie rods, hooks, brackets, welded structures, etc.
