Hot Rolled Welded Steel Plate Black Annealed Steel Coils

These black annealed steel coils are annealing then sent to straighten machine for straightening and pickling in acid. These annealed steel coils have a precision grinding machine with proper chamfering after the first shift operation. This hot-rolled welded steel coil is black without bright treatment, and its physical properties are soft, which is convenient for further welding to make steel pipes.

PRODUCT DETAILS

Product Description

These black annealed steel coils are annealing then sent to straighten machine for straightening and pickling in acid. These annealed steel coils have a precision grinding machine with proper chamfering after the first shift operation. This hot-rolled welded steel coil is black without bright treatment, and its physical properties are soft, which is convenient for further welding to make steel pipes.

The surface color turns black due to high-temperature contact with air, so it is called black annealed cold rolled steel coil. The surface of annealed steel coils is black, which is slightly cheaper than the bright ones. The black surface is not so bright. It’s a little black, but it’s a little more straight on the surface, and it’s used in some places where the requirements are not very strict.

Features:

  • Clean, smooth finish.
  • Good welding performance.
  • Good corrosion resistance, durable.
  • High strength and high-temperature oxidation.
  • Surface appearance and the use of the possibility of diversification.
