Annealing cold rolled steel must be annealed to restore its mechanical properties, and those without annealing are called hard rolled coils. Annealing cold rolled steel coils are generally used to make products that do not require bending or stretching, and those with a thickness of less than 1.0 are rolled on both sides or four sides with good luck.
