PRODUCT PARAMETERS

Carbon Steel: Properties, Production, Examples and Applications

Name: A213 Seamless Carbon Steel Pipe
SKU: 0

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

ASTM A213 or ASME SA213 seamless tube is applicable to seamless ferritic and austenitic pipes with the minimum thickness in boiler and superheater. It is typically used as heating surface pipe, boiler header and steam pipe in low and medium pressure boilers. This seamless steel pipe is widely applied in heat exchanger, condenser and heat transfer equipment. Selecting a steel pipe suitable for a specific application requires comprehensive consideration of multiple factors such as temperature, pressure, flow, material quality, corrosion protection and welding installation to ensure that the steel pipe can operate safely and reliably in the application scenario.
