DC03(St13)

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, DC03(St13) low carbon and ultra-low carbon automotive steel plates are suitable to simple forming , bending or welding.

Nominal thickness: 0.30mm~0.35mm, nominal width: 700mm~1850mm.

DC03(St13) low carbon and ultra-low carbon automotive steel tensile strain mark:

It is guaranteed that no tensile strain mark occurs on steel plates and strips at their application within 6 months after they are produced and in case of room temperature storage.

DC03(St13) low carbon and ultra-low carbon automotive steel surface quality:


Grade

Code No.

Features

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.
