    For quenched and tempered cold rolled strips, there are several possible surface finishes:

    The surface finish of annealed C67S 1.1231 steel strips after cold rolling and annealing in a controlled atmosphere is expected to be bright, resulting from the rolling and annealing processes.

    1.Grey/Annealed Oxide Finish: This finish is unpolished and retains a natural grey appearance with an oxide layer.

    2.Bright Tempered (Unpolished): In this case, the steel strip remains unpolished but exhibits a bright appearance due to the tempering process.

    3.Polished Finish: This finish is achieved by employing processes like fine grinding or abrasive brushing to create a smooth and reflective surface.

    4.Polished and Colored Finish: This finish involves heat treatment to create specific colors, such as annealed or yellow coloring, through oxidization processes.
