A GRADE BLACK ANNEALED
With high-quality hot-rolled coil as its materials, cold-rolled sheet is made in such a process as descaling through pickling multi-step deforming by rolling in the cold tandem mill , electro-cleaning and annealing as well as skinpassing and finishing, etc. The cold-rolled products have fine characteristic such as being accurate of machinery, processing characteristics and thickness, used with such trades as the architecture automobile, electrical home appliances, traffic, etc.
A grade black annealed is the first level product. Our factory is profession steel factory located in Liaoning province. Can provide good quality and price satisfied customer’s different requirement .

This steel has been annealed, heating the steel to the appropriate temperature for a certain period of time and then slowly cooling. The hardness of the annealed steel is reduced and the plasticity is greatly improved, which is advantageous for cutting and cold deformation processing about steel. In addition, in the annealed steel, the crystal grains are refined, the structure and composition of the steel become more uniform, the properties thereof are well improved, and the subsequent heat treatment of the steel is facilitated. In addition, the annealing treatment also eliminates the internal stress in the steel, which makes the steel free from deformation or cracking.
