Cold Rolled Steel

    Cold rolled carbon sheets are manufactured from hot rolled pickled coils by cold reducing to the ordered thickness, followed by annealing to recrystalize the grain structure. The annealed product can be used as annealed (dead soft) for unexposed applications.

    For exposed applications, the annealed sheet product is given skin or temper pass to minimize fluting and to impart suitable texture. Cold rolled sheet steel can also be furnished in the full hard (unannealed) condition.
