— for steel size over 80 to 150 mm — 4% of the size (diameter or thickness);

— St. steel size 150 mm — 5% of the size (diameter or thickness).

The depth of defect count from the nominal size.

3.7. The surface quality of drawn steel must comply with trebovaniye 1051, group, steel with special surface finish or honed — GOST 14955, groups B, C, d, E. Group of a surface point in the order.
