Steel Pipes by Material » Carbon Steel Pipes & Tubes

The steel with slight quantity of elements other than carbon, silicon, sulphur and manganeses is called carbon steel. These are the alloyed iron with carbon as main constituent. The amount of carbon content in the steel pipe determines its hardness and strength but on other hand it makes the steel more ductile. The carbon steel is tougher to melt and the high carbon content reduces weldability as well. Based on the properties and alloyed elements, carbon steel can be classified into four classes.

Classes of steel carbon	Carbon content %
Ultra high carbon steel	0.75 - 1.70
High carbon steel	0.45 - 0.75
Medium carbon steel	0.30 - 0.45
Low carbon steel	0.05 - 0.30

Carbon steel falls in range of steel between ingot iron and cast iron. They are cheaper and durable than the rest steel. It is the most used material in steel segment and holds 85% of the total steel production. The carbon steel pipes & tubes are stronger and has ultimate tensile strength. Since, it is light weighted carbon steel pipes & tubes are used in marine application, nuclear projects and other high pressure exposures.
