for alloyed hot-dip galvanized products, the allowable reduction of min. Percent elongation and r90 specified can be respectively by 2% and 0.2.
BH refers to the increment of tested y2 170°c±5℃ for 20 minutes.
In case the total weight of two coating sides is larger than 180g/m², the bending center diameter will increase by 1a; for differential coated products, the thicker coating is used as outside surface in bending test.

H220PD+Z hot dip galvanized automotive steel surface quality:
|
Code No. |
Features |
|
FB(O3) |
It is allowed for the existence of small erosion spots, dark spots, strip marks, minor chromate treatment defects and small zinc particles. |
|
FC(O4) |
No erosion spot is allowed. However, it is allowed for the existence of light impression, scratches, zinc flow ripple marks, minor chromate treatment defects in small range, while the other side must reach FB requirements at least. |
|
FD(O5) |
One side of relatively good quality must further restrict on defects, namely appearance quality after painting is not affected, and the other side must FB requirements at least. |
