PRODUCT PARAMETERS

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.


Types of carbon steel and their properties


Carbon steel can be classified into three categories according to its carbon content: low-carbon steel (or mild-carbon steel), medium-carbon steel and high-carbon steel . Their carbon content, microstructure and properties compare as follows:


Carbon content (wt.%)MicrostructurePropertiesExamples
Low-carbon steel< 0.25Ferrite, pearliteLow hardness and cost. High ductility, toughness, machinability and weldability
Medium-carbon steel0.25 – 0.60MartensiteLow hardenability, medium strength, ductility and toughness
High-carbon steel0.60 – 1.25PearliteHigh hardness, strength, low ductility

PRODUCT DETAILS

A106  Grade B Steel Pipe Description
A106 steel pipe is a low carbon  steel pipe whose main components are carbon, silicon, manganese and small  amounts of chromium, copper, nickel and molybdenum. It is a seamless steel  pipe suitable for transporting liquids and gases in high temperature and high  pressure environments. The manufacturing process of A106 steel pipe usually includes  steps such as hot rolling, cold drawing and cold working. During these  processes, the internal structure of the pipe is made tighter through heat  and pressure treatment, thereby improving its strength and corrosion  resistance. A106 steel pipe can be used in many different fields, such as  oil, natural gas, chemical industry, electric power, shipbuilding, aerospace,  etc..
