2-1> PRODUCT DESCRIPTION:

      Cold-rolled sheet (annealed) :

      The cold-rolled sheet is annealed under the hood before rolling, and the work hardening phenomenon 
      and internal stress are eliminated (greatly reduced) after annealing, that is, the yield strength 
      is reduced close to the cold rolling before.

      The cold-rolled sheet coil consists of sheet and coil, which is rolled at room temperature and below the
      recrystallization temperature.

     Among them, the delivery of sheets is called steel plate, also known as box plate or plate; The long length 
     and roll delivery are called steel belts, also known as roll plates.

     Specification:

     Thickness of 0.2-4mm,

     Width of 600-2000mm,

     steel plate Length of 1200-6000mm.

     Grade:

     Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B); SPCC, SPCD, SPCE, ST12-15; DC01-06

     Performance:

     Mainly used low carbon steel grades, requiring good cold bending and welding performance, as well as 
     a certain stamping performance.

     Coil

     Coil is a kind of plate in steel, which is actually a thin steel plate that is long and narrow and supplied in rolls.

     The difference between a roll and a plate is a cut package.

     Chilled coil is hot rolled coil through pickling and cold rolling. It can be said that it is a kind of cold rolled
     sheet coil.

     Cold rolled coil (annealed) : hot rolled coil is obtained by pickling, cold rolling, hood annealing,
     leveling, (finishing).

     There are three main differences between the two:

     1. In appearance, the general chilled coil is a little faint.

     2. surface quality, structure, dimensional accuracy and other cold-rolled plate is better than cold-rolled plate.

     3. in terms of performance, due to the cold-rolled coil directly obtained by the cold-rolled process, the 
         cold-rolled coil occurs work hardening during cold rolling, resulting in an increase in yield strength 
         and residual part of the internal stress, and the external performance is relatively "hard",
         so it is called cold-rolled coil.

     Therefore, the yield strength: the cold-rolled coil is greater than the cold-rolled coil (annealed), which makes 
     the cold-rolled coil (annealed) more conducive to stamping.

     Generally, the default delivery condition of cold rolled coil is annealed.

     There are many models of cold rolled steel coils, some of which are common include:

     - SPCC, SPCD, SPCE, ST12-15;
     - DC01-06;
     - Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B);
     - Ordinary carbon structural steel coil: thickness 1.2-14mm, width 600-2000mm;
     - Low alloy high strength structural steel coil: thickness 1.2-14mm, width 600-2000mm;
     - Cold rolled silicon steel coil: thickness 0.3-1.0mm, width 800-1300mm;
     - Stainless steel coil: thickness 0.3-6mm, width 1000-2000mm;
     - Galvanized steel coil: thickness 0.3-4mm, width 800-2000mm.

                    Note:
                   a) Transverse style is taken for tensile test; The pattern width b is 25mm
                         and the pattern mark distance L0 is 50mm.
                   b) When there is no obvious yield point, Rel can be replaced by Rp0.2;
                         When the thickness of the product is < 0.70mm and ≥0.50mm,
                         the upper limit of the yield strength can be increased by 20N/mm2,
                         and when the thickness is < 0.50mm, it can be increased by 40N/mm2.
                    e) When the thickness of the product is > 1.50mm and ≤2.0mm,
                         the value of r90 or r is allowed to be reduced by 0.1 (absolute value);
                         When the thickness is > 2.0mm,
                         the value of r90 or r can be reduced 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.
