Q345C Carbon Steel Coil,
ASTM Carbon Steel Coil
High Strength Steel Plate Anti-Finger Carbon Steel Coil
Coil is a type of plate, which is actually a thin steel plate that is long and narrow and supplied in coils. The main difference between Coiled plate and flat sheets lies in cutting and packaging.
Coil is divided into chilled coil plate and cold rolled coil plate
Chilled Coil are obtained by pickling and cold rolling of hot-rolled coils plate. It is a cold rolled coil plate. Cold-rolled coil plate (annealed): It can be obtained from hot-rolled coils plate through pickling, cold rolling, bell annealing, flattening, (finishing) processing.
There are three main differences between the two:Generally the default delivery state of cold rolled coil plate is annealed state.
1. In appearance, the color of chilled coils plate is generally micro black color.
2. In terms of surface quality, structure, and dimensional accuracy, cold-rolled coil plate are better than chilled coils plate.
3. In terms of performance, because the chilled coils plate directly obtained from the hot-rolled coils plate through the cold rolling process undergo work hardening during cold rolling, the yield strength is increased, and some internal stresses remain, and the external performance is relatively "hard". Called chilled coil plate. And cold-rolled coil plate (annealed): It is obtained from the chilled coil plate through bell annealing before coiling. After annealing, the work hardening phenomenon and internal stress are eliminated (greatly reduced), that is, the yield strength decreases close to the cold Before rolling. Due to the yield strength, chilled coils are larger than cold-rolled coils plate (annealed), making cold-rolled coils plate (annealed) more conducive to stamping and forming
Generally the default delivery state of cold rolled coil plate is annealed state.
Most steel is sold in coils. Enterprises in the purchase of coil after the uncoiling process can be processed, generally used in the automobile industry more.
