Carbon steel, also called plain-carbon steel, is steel where the main alloyingconstituent is carbon. The American Iron and Steel Institute (AISI) definescarbon steel as: "Steel is considered to be carbon steel when no minimum contentis specified or required for chromium, cobalt, columbium, molybdenum, nickel,titanium, tungsten, vanadium or zirconium, or any other element to be added toobtain a desired alloying effect; when the specified minimum for copper does notexceed 0.40 percent; or when the maximum content specified for any of thefollowing elements does not exceed the percentages noted: manganese 1.65,silicon 0.60, copper 0.60."

The term "carbon steel" may also be used in reference to steel which is notstainless steel; in this use carbon steel may include alloy steels.

Applications

Carbon Steel is used in the most critical engineering applications and alsoin certain applications in the automotive sector. In addition, some of thevalue-added Carbon Steel products include steel for LPG cylinders, API grade,corrosion resistant steel, critical structural application steel, boilerquality, auto grades, precision tubes and medium/high carbon grades, amongothers.
