Properties: Cold-Rolled Black Annealed (CRBA) (also known as Blue Steel) is Cold Rolledsheets that have been oxidized by annealing in a special installation to produce a very thin magnetite layer (Fe304) on the surface (less than 1 μm thick) for more protection.

Advantages: Cold Rolled Black Annealed provide protection against corrosion for parts whose surfaces cannot be protected by normal painting or any metallic coating processes. The magnetite layer can withstand moderate bending and drawing operations. The sheet surface is very clean and retains its attractive appearance during storage.

Application: The main areas of use are:
● 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.
● Cold Rolled Black Annealed are suitable for food contact, under certain conditions
