The chemical composition of a 0.2mm non-sharp steel plate would depend on the specific type of steel being
referred to. However, as a general reference, the following are some common elements found in steel:
Iron (Fe)
Carbon (C)
Manganese (Mn)
Phosphorus (P)
Sulfur (S)
Silicon (Si)
Therefore, the chemical composition of a 0.2mm non-sharp steel plate may contain some or all of the above
elements, depending on the specific composition and manufacturing process used for the steel.
