Plain Carbon Steel Plain Carbon Steel Plain Carbon Steel Plain Carbon SteelPlain carbon steel sheet and strip are used primarily in consumer goods. These applications require materials that are
serviceable under a wide variety of conditions and that are especially adaptable to low-cost techniques of mass production
into articles having good appearance. Therefore, these products must incorporate, in various degrees and combinations,
ease of fabrication, adequate strength, excellent finishing characteristics to provide attractive appearance after fabrication,
and compatibility with other materials and with various coatings and processes.
The steels used for these products are supplied over a wide range of chemical compositions (see Tables 1 and 2);
however, the vast majority are unalloyed, low-carbon steels selected for stamping applications, such as automobile bodies and appliances. Thus, this section of the article will focus on low-carbon steel applications. For these major applications,
typical compositions are 0.03 to 0.10% C, 0.15 to 0.50% Mn, 0.035% P (max), and 0.04% S (max).
