ABSTRACT
Steels may be classified in many ways: by composition, such as by carbon content or alloying element in case of the low-alloy steels; finishing methods, such as hotor cold-rolled; form, such as plate, sheet, strip, rod, tubing, etc.; deoxidation process, such as killed, semikilled, capped, or rimmed steel. The most common manner of classification is according to composition with the carbon steels being grouped according to carbon content and the alloy steels, which are generally heat-treated to obtain their desired properties, according to the major alloying elements (i.e., nickel, chromium, molybdenum, and combinations of these elements).
