Surface classification of S235JR carbon steel plate General grade surface (FA) of S235JR carbon steel plate:
The surface of the pickling surface allows a slight, partial defect, such as pits, concavities, scratches, etc., which have a depth (or height) not exceeding the tolerance of the plate thickness, but shall ensure the minimum thickness allowed for the steel plate and strip.
Higher level surface (FB) of S235JR carbon steel plate:
The surface surface of the pickling is allowed to have local defects that do not affect the formability, such as minor scratches, slight indentation, slight pitting, slight roll and chromatic aberration.
