Carbon steel pipe in the performance of the outstanding performance is high yield strength and stress corrosion resistance, has good weldability, welding cold crack and hot crack are less sensitive.
Carbon steel tubes are divided into hot rolled and cold rolled (drawn) steel tubes.
Hot rolled carbon steel tubes are divided into general steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological tubes and other steel tubes.
Carbon Steel: Properties, Production, Examples and Applications Carbon steel is an iron-carbon alloy, which contains up to 2.1 wt.% carbon. For carbon steels, there is no minimum specified content of other alloying elements, however, they often contain manganese. The maximum manganese, silicon and copper content should be less than 1.65 wt.%, 0.6 wt.% and 0.6 wt.%, respectively.
