2B, 2D and BA Cold Rolled Finishes - ASSDA
Bright Annealed [BA] Finish- A smooth, bright, reflective finish typically produced by cold rolling followed by annealing in a protective atmosphere so as to prevent oxidation and scaling during annealing. 2B. 2B is the most widely used stainless steel surface finish. Black Annealed Bright Cold Rolled Steel Plate Machining - Image ResultsBatch Annealing Services. 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.

Steel Bright Bar Flats have sharp corners compared to the flats that are cold rolled. The surface of these Steel Bright Bar Flats is bright, smooth and does not have uneven surface differentiating it from hot rolled flats. Cold Drawn Steel Bar and Bright Drawn Round/ Square/ Flat BarsSteel Bright Bar or Cold Drawn Steel Bar are steel bars formed by cold drawing hot rolled steel bars using dies. A bright steel bar is a carbon or alloy steel bar with a gleaming bright surface that has been enhanced by cold drawing, peeling, spinning, grinding, and polishing over hot rolled black surface bars. Cold drawing increases the yield power and tensile strength of steel bars. The surface imperfections can be extracted by peeling and flipping.

Confused about Annealing / Heat Treating Terminology black annealed bright cold rolled steel plate MachiningMartensitic steels are annealed at lower temperatures (around 1400 F/760 C) and slow cooled. Most martensitic steels are used in a thermally hardened condition. This is accomplished by heating annealed material to a much higher temperature (1950 F/1065) and quenching as rapidly as possible. This is a hardening treatment, not annealing. Difference Between Black Steel and Bright Drawn Steel | Metal black annealed bright cold rolled steel plate MachiningBright drawn steel is essentially black steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes.
Difference Between Hot and Cold Rolled Steel | Metal Supermarkets
The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by black annealed bright cold rolled steel plate Machining Fatigueproof-Cold Finished Carbon Steels On Fay Industries black annealed bright cold rolled steel plate MachiningThese properties are produced by a process of drawing steel at elevated temperatures, developed and patented by LaSalle Steel Co. The result is a steel with high tensile strength, uniformity of properties, and excellent machinability. This product possesses high strength as it is received from the mill, and no subsequent heat treatment is more.
