What are Carbon Steel Products?
Carbon steel products are items made from carbon steel, known for its strength and hardness. Common products include gears, springs, bolts, kitchen knives, wires, cables, bridges, ball bearings, and airplane components. Carbon steel is favored for its ability to withstand significant force and its versatility in various applications.

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.%) | Microstructure | Properties | Examples | |
|---|---|---|---|---|
| Low-carbon steel | < 0.25 | Ferrite, pearlite | Low hardness and cost. High ductility, toughness, machinability and weldability | AISI 304, ASTM A815, AISI 316L |
| Medium-carbon steel | 0.25 – 0.60 | Martensite | Low hardenability, medium strength, ductility and toughness | AISI 409, ASTM A29, SCM435 |
| High-carbon steel | 0.60 – 1.25 | Pearlite | High hardness, strength, low ductility | AISI 440C, EN 10088-3 |

FAQs
Carbon steel is an iron-carbon alloy with less than 2% total alloying elements. Key compositional limits include up to 0.6% copper, 1.65% manganese, 0.04% phosphorus, 0.6% silicon, and 0.05% sulfur. No other elements are intentionally added to alter its properties.
In steelmaking, carbon is added in the form of solid carbon sources like graphite or carbon black. These materials are either mixed into the steel alloy during melting or added as a separate step afterward to achieve the desired carbon content.
Carbon steel’s disadvantages include difficulty in bending and shaping due to its strength, which limits its versatility. It is also more susceptible to rust and corrosion compared to other steels, requiring additional protection or coatings to prevent deterioration in harsh environments.
