Annealing of 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 Annealing of Cold Rolled Steel IspatGuruContinuous annealing of cold rolled steel was first introduced by the Armco steel corporation in the year 1936 as a process step in the production of hot dip galvanized steel.Since then several improvements have been made in the process which allows several types of steels to be processed by this method.All Metals Standards - ASTM InternationalA794/A794M-18 Standard Specification for Commercial Steel (CS),Sheet,Carbon (0.16 % Maximum to 0.25 % Maximum),Cold-Rolled.A795/A795M-13 Standard Specification for Black and Hot-Dipped Zinc-Coated (Galvanized) Welded and Seamless Steel Pipe for Fire Protection Use
