Product Description

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:

Scope Of Application

Carbon steel is an alloy steel, mainly composed of iron, carbon and a small amount of silicon, manganese and other elements. Carbon steel is widely used in the following scenarios:


1. Construction industry

Carbon steel is widely used in the construction industry, mainly used to manufacture steel bars, steel plates and other building structural parts, such as bridges, buildings, etc. Carbon steel has very high hardness and strength, can withstand greater pressure and weight, and can ensure the structural stability and safety of the building.


2. Machinery manufacturing industry

Carbon steel is also widely used in the machinery manufacturing industry, mainly used to manufacture parts and structural parts of various mechanical equipment such as machine tools and excavators. Carbon steel has high strength and wear resistance, which is very suitable for machinery manufacturing that requires high strength and wear resistance.


3. Automobile manufacturing industry

Carbon steel is also a very common metal material in the automobile manufacturing industry, mainly used to manufacture automobile frames and structural parts. Carbon steel has high strength and durability, which can ensure the safety and service life of the car. At the same time, carbon steel also has good plasticity and weldability, which can be easily processed and assembled
