What is Composition of Low-carbon Steel - Definition

Composition of Low-carbon Steel. Low-carbon steel contains approximately 0.05–0.25% carbon making it malleable and ductile. Microstructures consist of ferrite and pearlite constituents.

Low-carbon steel, also known as mild steel is now the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications. Low-carbon steel contains approximately 0.05–0.25% carbon making it malleable and ductile. Mild steel has a relatively low tensile strength, but it is cheap and easy to form; surface hardness can be increased through carburizing.

Typical applications include automobile body components, structural shapes (e.g., I-beams, channel and angle iron), and sheets that are used in pipelines, buildings. For example, A36 steel is a common structural steel in the United States. Low-carbon steel sheets used for car body applications, for example, are subjected to a variety of forming operations, including deep drawing. Microstructures consist of ferrite and pearlite constituents. As a consequence, these alloys are relatively soft and weak but have outstanding ductility and toughness. In addition, they are machinable, weldable, and, of all steels, are the least expensive to produce. Density of this metal is 7861.093 kg/m³ (0.284 lb/in³) and the tensile strength is a maximum of 500 MPa (72500 psi).
