S320GD+Z hot dip galvanized plates(coils) are featured with strong coating adhesiveness, high erosion-resistance, accurately controlled zinc coating thickness, high size precision, flat profile and good mechanical, processing and welding performance. They can be used for making outside and inside automotive plates, structural parts and reinforcements.
S320GD+Z hot dip galvanized automotive steel size:
Nominal thickness: 0.30mm~3.0mm, nominal width: 800mm~1830mm
Note: nominal thickness of a plate/strip is sum of base plate
thickness and coating thickness.
S320GD+Z hot dip galvanized automotive steel mechanical performances and coating adhesiveness:
Steel grade | Mechanical performances | Coating adhesiveness | |||
Yield strength MPa≥ | Tensile strength MPa≥ | After breakage percent elongation %≥ | Bending center diameter ( a=plate thickness) | ||
L0=80mm, b=20mm | |||||
Nominal thickness mm | |||||
≤0.7 | >0.7 | ||||
S320GD+Z, S320GD+ZF | 320 | 390 | 15 | 17 | 3a |
a.bending center diameter is 4a in case of nominal thickness>1.5mm.
S320GD+Z hot dip galvanized automotive steel coating weight range:
Coating form | Applicable surface structure | Weight range of following coatings a g/m²(A/B) | |
Zinc coating | Zn-Fe alloy coating | ||
Equally coating | Z, X, G, GX, N, R | 40/40~225/225 | 30/30~90/90 |
Differential coating b | N, R | 30~150(each side) | - |
a. 50 g/m² coating weight is equivalent to about 7.1µm. b. max. differential coating thickness ration is 1:3. |
S320GD+Z hot dip galvanized automotive steel surface treatment:
1 Chromate treatment (L) | Chromate treatment is a treatment with an aim to prevent white rusts formed on product surfaces during transportation and storage. |
2 Oiling (Y) | Oiling is to prevent white rusts formed on product surfaces during transportation and storage. |
3 Chromate treatment + oiling (LY) | This treatment with oiling after surface chromate treatment is to further avoid the forming of white rusts. |
S320GD+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. |
Aplication:
(1) Type of zinc coating finish: regular spangle, minimized spangle
and skin-pass.
(2) Types of surface qualities: as coated surface, improved surface
and best quality surface.
(3) Surface treatment: chemically passivated, chromate-free
passivation, phosphate, anti-finger print, phosphateand, self
lubricating film, and untreated.
(4) Type of oiling: oiled and unoiled.
(5) Coil ID: 508/610mm.
(6) Grade: SGCC, DX51D, ASTM A653 CS TypeB, etc; Application:
container plate.
