Carbon Steel Pipe & Tubes

 

Carbon steel, also called plain-carbon steel, is steel where the main alloying constituent is carbon. The American Iron and Steel Institute (AISI) defines carbon steel as: "Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following 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 not stainless steel; in this use carbon steel may include alloy steels.

As the carbon content rises, steel has the ability to become harder and stronger through heat treating, but this also makes it less ductile. Regardless of the heat treatment, higher carbon content reduces weldability. In carbon steels, the higher carbon content lowers the melting point.



 Applications

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