7. surface quality
Plate shall be rolled surface and of uniform quality.
The surface of the plate does not allow cracks, corrosion, pine dendritic patterns, etc. to affect the use of defects.
Slight oil marks are allowed on the surface of the sheet, but the oil Mark area should not exceed 10 % of the surface
On either side of the sheet, there shall be no more than four other unspecified defects per two square metres. Each area shall not exceed 50mm x 50mm, where the depth of the defect shall not exceed half of the thickness allowed to pass, and the other side of the sheet shall allow other unspecified faults to exist, and the depth shall not exceed the thickness allowed to pass
