The surface of cold rolled black annealed crca steel coil is black without bright treatment, and its physical properties are soft, which is convenient for further welding to make steel pipes. The common hardness is 57HRB, but it can be reduced to different hardness as required.

Generally speaking, the elongation property of black annealing cold rolling is better. The difference between cold rolled pockmarked surface and bright one lies in the good or bad surface quality. cold rolled coils with more pits or pits are cold rolled pockmarked surface, while bright ones basically have no pockmarked surface or pits. Black retreat after cold rolling means that the surface of annealed strip steel is black, which is slightly cheaper than bright one

Applications of 0.5mm cold rolled CRCA black annealed steel coils :

• All kinds of Steel pipes and tubes (Stove pipes)
• Food contact other than packaging
• Cake and biscuit molds
• Baking trays
• Lining of industrial bread ovens
• Furniture & construction
• Economical general items where they don’t need further painting, etc.
