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 [1]. 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

FAQ

A:

All our steel products are manufactured using genuine materials that meet national standards; we strictly adhere to national production regulations and strictly prohibit the use of non-standard specifications, adulterated materials, or defective goods. For every shipment, we provide a complete set of documentation—including material specifications, quality inspection reports, and factory certificates—free of charge. Our products support third-party re-inspection, on-site acceptance, and project filing, ensuring full traceability of quality throughout the process.

A:

We support custom processing for a full range of steel products. For items such as steel plates, profiles, pipes, and round bars, we provide tailored services—including cutting, bending, drilling, trimming, beveling, anti-corrosion painting, and hot-dip galvanizing—based on client construction drawings and on-site requirements. We can process materials to any dimension or non-standard specification, meeting the unique needs of various engineering projects and equipment manufacturing applications.

A:

We offer free sample delivery. To ensure peace of mind during the procurement process, we provide steel samples matching your specifications, allowing you to verify material quality, check manufacturing processes, and facilitate acceptance inspections by the project owner. Testing samples prior to placing bulk orders helps minimize procurement risks.

A:

Steel is a commodity with prices that fluctuate in real-time based on futures markets, raw material costs, and inventory levels; since fixed list prices can lead to discrepancies, we provide standardized, real-time manual quotes. All pricing is transparent with no hidden costs; quotes can be provided on either a tax-inclusive or tax-exclusive basis, and special VAT invoices can be issued upon request.

A:

Our company has no strict minimum order quantity requirements and supports various procurement models, including small-scale purchases, bulk stocking, and full-order supply for engineering projects. We can handle orders ranging from small top-up supplies for construction sites and ad-hoc store purchases to bulk procurement for large-scale projects, flexibly meeting the diverse needs of our customers.
