steel - steel - Primary steelmaking: In principle, steelmaking is a melting, purifying, and alloying process carried out at approximately 1,600° C (2,900° F) in molten conditions. Various chemical reactions are initiated, either in sequence or simultaneously, in order to arrive at specified chemical compositions and temperatures. Indeed, many of the reactions interfere with one …
Following is a list of some important chemical elements used in structural steels: Carbon (C) Next to iron, carbon is by far the most important chemical element in steel. Increasing the carbon content produces a material with higher strength and lower ductility. Structural steels, therefore, have carbon contents between 0.15 to 0.30 percent; if ...
