Carbon Steel Welded Pipes / Tubes
Carbon steel is characterized by high strength, high hardness, corrosion resistance, wear resistance.
Carbon steel is a carbon and iron alloy with a carbon content of up to 2.1% by weight.The increase of carbon content will increase the hardness and strength of steel, but reduce the toughness of steel.Carbon steels have good strength and hardness, and are much cheaper than other steels.
