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.%) Microstructure Properties Examples
Low-carbon steel < 0.25 Ferrite, pearlite Low hardness and cost. High ductility, toughness,  machinability and weldability
Medium-carbon steel 0.25 – 0.60 Martensite Low hardenability, medium strength, ductility and  toughness
High-carbon steel 0.60 – 1.25 Pearlite High hardness, strength, low ductility

PRODUCT DETAILS



A106GrB  Seamless Steel Pipe Description
A106GrB Pipe is a seamless ferritic alloy-steel  Pipe for high temperature service. Pipe of this specification are suitable for bending, flanging, and similar forming  operations, and for fusion welding. Generally, ASTM A335 P11, P22, and  P91 pipelines are used for power generation and downstream oil and gas, and  P5 and P9 grades are used for refinery applications. A335 steel pipe not only has high oxidation resistance and high  temperature steam corrosion resistance,but also has good impact  toughness,stable durable plasticity and thermal strength. A335 steel pipes are commonly  used to transport high-temperature and high-pressure oil, natural gas and  other media.
