Features of Black Annealed Cold Rolled Coil
After the steel plate undergoes black annealing treatment, a better balance between strength and toughness is achieved, and the work hardening phenomenon is alleviated.
Black annealed cold-rolled coil has good thickness uniformity and high precision in width and length.
The surface is smooth and flat, which is conducive to improving the effects of surface treatments such as painting and coating on the material.
An oxide film is formed on the surface. With good coating performance, the corrosion resistance of the material is improved.
