Annealing cold rolled steel involves a time and temperature controlled thermomechanical process used predominantly to make steel soft again after cold reduction.. Cold reduction or work hardening makes steel grain structure small and elongated.. This produces high strength, but low elongation. Annealing recrystallizes the grain structure restoring ductility so the material can adequately bend Bright Black Annealed Full Hard Cold Rolled Steel CoilBright Annealled Steel, Colled Rolled Steel, Black Annealed Steel manufacturer / supplier in China, offering Bright Black Annealed Full Hard Cold Rolled Steel Coil, Ms Sheet Metal!

Cold Rolled Black Annealed (CRBA), also known as "Blue Steel". CRBA is a cold rolled sheets that have been oxidized by annealing in a special installation in order to produce a very thin magnetite layer (Fe304) on the surface (less than 1 m thick) for more protection. Cold Rolled Black Annealed provide protection against corrosion for the parts whose surface is not protected by normal painting or any
