Giriş
Carbon steel is highly used in industries. A few of them are car manufacturing industries, machinery and tool manufacturing, as well as the construction industry, where carbon steel is used in their operations.
It is important to remember that the largest constituent of this steel is carbon, the smaller parts of which are manganese, silicon, and other alloying metals.
Reading this article, you can get to know which kind of properties and the simplest information about the carbon steel density. Unassisted, you directly measure the strength, ductility, machinability, and thermal performance of the material.
What is the Density of Carbon Steel?
The manufacturers of boiler pipes and tubes must get familiar with the concept of density. The density is the adjustment of a given material in each space, and how closely the molecules are packed together. The density of the steel is roughly 490 pounds per cubic foot, or 7.85 g/cm³ or 7850 kg/m³.
Carbon steel typically has a density of 7.75 g/cm³ to 8.05 g/cm³, corresponding to a density of 7,750 kg/m³ to 8,050 kg/m³. That is some 0.282 to 0.291 lb / in³ in imperial units. The average density of 7.85 g/cm³ (7,850 kg/m³, 0.284 lb/in³) is the most quoted one. This is an average of the most popular grades, including ASTM A36, Grade B, A106, and A53.
What effects does density have on the characteristics of carbon steel?
The steel’s carbon content, which influences its density, is the main source of variation. Here is the detail:
Strength‑to‑Weight Ratio
A manufacturer must know that a higher carbon content in carbon steel will tend to make it denser. Some people make bridges, pressure vessels, and large machinery by using high-carbon steel.
Hardness and Ductility
Its strength and flexibility make carbon steel suitable for making hard and ductile materials. The manufacturer must know that the flexibility is inversely related to the carbon content in the carbon steel, while strength is directly associated with it.
Thermal Properties
Higher heat capacity and thermal expansion coefficients are seen in denser carbon steels. Before they reach the crucial temperature, they retain more heat.
Electrical Conductivity
An increase in density implies a reduction in electrical conductivity, as resistivity increases.

Corrosion does not necessarily depend on density, but the higher the atomic crowding of steel, the better the material’s resistance to environmental impact.
Composition and Types of Carbon Steel
The manufacturer must recognize that the carbon content of the material significantly influences the density and performance characteristics of steel.
Low-carbon (mild) steel
- The carbon content is approximately 05%–0.25%.
- The density is 85 g/cm³.
- Common grades include AISI 1018, ASTM A36.
- Low-carbon steel can be used in structural beams, pipes, automobile panels, and fasteners.
- It has good ductility, weldability, and machinability.
Orta karbonlu çelik
- The Carbon content is about 0.25%–0.60%.
- Density maintained as 83 g/cm³.
- Common grades include AISI 1045 and AISI 1055.
- It can be used for making axles, gears, machinery parts, and shafts.
- Strength and ductility are balanced.
High-carbon steel
- Density is lowered to 81 g/cm³.
- Between 0.60 and 1.00% carbon is present.
- Common grades include AISI 1075 and AISI 1095.
- It could be used in cutting tools, knives, and wear-resistant parts.
- Brittle, hard, and strong. It must be heat-treated in a special manner that enhances its toughness.
There is a slight decrease in density with an increase in carbon content, approximately 0.02 g/cm³ per 0.1% rise in carbon content. It happens because the increase reduces the atomic spacing in the carbon content.
Sonuç
The density of the carbon steel directly affects its strength, ductility, and performance in different sectors. The change in the content of carbon leads to the product having different properties and densities, which makes it applicable for use in various industries.
As a manufacturer, one must have an acquaintance with the nature of the different properties of carbon steel that have varying carbon content to enable the engineers and the manufacturers to make their decisions based on the application.
