BLC low carbon and ultra-low carbon automotive steel
With excellent drawing and welding performance and relatively high dimensional accuracy, the clod rolled low carbon and ultra-low carbon steel plates provided by JW STEEL have been widely applied to manufacture of various automotive parts. With some ductibility, BLC low carbon and ultra-low carbon automotive steel plates are suitable to simple forming , bending or welding.

|
Relatively high-grade finishing surface |
FB(O3) |
It is allowed for the existence of a few surface defects which will not affect forming and coating & plating adhesiveness such as minor scratch, impression, pit, roll mark and oxidation tint. |
|
High-grade finishing surface |
FC(O4) |
One side of relatively good quality is free from any remarkable defect visible and the other side must reach FB requirements at least. |
|
Ultra high-grade finishing surface |
FD(O5) |
One side of relatively good quality is free from any defect, namely appearance quality after painting or electrogalvanizing is no affected, and the other side must reach FB requirements at least. |
Currently, main domestic makers for sedans and passage cars all use great amount O5 plates for large outside cover parts such as outside door plates, luggage boot cover plates, outside side plates and top covers. They show excellent application effects and can substitute imported steel plates.
