Carbon Steel Seamless Pipes / Tubes

Carbon Steel Seamless Pipes / Tubes

The properties of carbon steel are high hardness, strength, wear resistance and anti-corrosion.

Carbon steel is an alloy consisting of iron and carbon. The percentage of carbon in the steel affects the hardness, strength of elasticity and ductility of carbon steel. As the carbon percentage content rises, steel is harder and stronger but less ductile. Carbon steel has high hardness, toughness and strength, and it is relatively inexpensive compared to other steels.
