Carbon Steel Pipes/Tubes

In Carbon Steel, Carbon as the main alloying element. In carbon steel, the properties are mainly defined by the amount of carbon it has. For this alloy, the amounts of other alloying elements like chromium, manganese, cobalt, tungsten are not defined.

They are widely used in various industrial applications like Oil & Gas, Petroleum, Petrochemical, Chemical, Machine Building, Automobile, etc.
