Surface classification editing broadcast

Ordinary surface (FA)

The pickled surface is allowed to have slight and local defects such as pits, dents, scratches, etc. whose depth (or height) does not exceed half of the thickness tolerance of the steel plate, but the minimum allowable thickness of the steel plate and steel strip shall be guaranteed.

Higher surface (FB)

The pickling surface is allowed to have local defects that do not affect the formability, such as slight scratches, slight indentations, slight pits, slight roller marks and color differences.
