The brief introduction to black steel sheet
Black sheets, which are the main products of large steel factories, have a wide range in terms of steel type, thickness and dimensions. The most common types of steel sheet produced in Iran are St37 and St52 sheets. The chemical analysis of these plates can be seen in the DIN 17100 standard. Of course, it should be noted that this standard has not been valid since 1980 and was replaced by BS EN 10025.
In this standard, for the equivalent class St37, its equivalent in the EN standard known as S235JRG2 should be sought. The reason why this steel is still called St37 in Iran is that the steel product assortment is not enough to require new and global names and abbreviations. However, it should be kept in mind that a wide range of thicknesses from 1 mm to 10 cm can be seen in black sheets in terms of size and dimensions. As the thickness increases, the product becomes a plate and its ductility decreases. As you can see in Figure
