Product Details

With excellent drawing and welding performance and relatively high dimensional accuracy, the clod rolled low carbon and ultra-low carbon steel plates provided byMittel  have been widely applied to manufacture of various automotive parts. With some ductibility, DC04(St14, St15) low carbon and ultra-low carbon automotive steel plates are suitable to simple forming, bending or welding.

DC04(St14, St15) low carbon and ultra-low carbon automotive steel plates sizes:
Nominal thickness: 0.30mm~0.35mm, nominal width: 700mm~1850mm.

DC04(St14, St15) 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.

DC04(St14, St15) low carbon and ultra-low carbon automotive steel surface quality:

Code No.Features
Relatively high-grade finishing surfaceFB(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 surfaceFC(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 surfaceFD(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.
