To sum up, although the main component of steel bars is iron, it is defined as steel according to their carbon content and use.

Rebar is a steel whose main component is iron, but it is strictly defined as steel. The following is a detailed explanation

‌Composition of steel bars

The main component of steel bars is iron, and it also contains trace elements such as carbon, manganese, and silicon. The content of these elements determines the properties of the steel bars, such as strength, toughness and weldability.

Definition of steel bars

The word "steel" is used in the naming of steel bars, which indicates that it belongs to the category of steel. The difference between steel and iron is the carbon content: the carbon content of steel is usually between 0.02% and 2.11%, while the carbon content of iron is lower or higher.

‌The use of steel bars

Rebars are mainly used in reinforced concrete structures, which withstand tensile stresses and enhance the stability and safety of building structures. Its shape includes light round steel bars and deformed steel bars, which are widely used in various building structures.

‌Properties of steel bars

The properties of steel bars are determined by their chemical composition. For example, an increase in carbon content will increase the strength of the steel bars, but will reduce their plasticity and toughness; manganese and silicon will help improve the hardness and wear resistance of the steel bars.

To sum up, although the main component of steel bars is iron, it is defined as steel according to their carbon content and use.

Are stainless steel coils and stainless steel plates the same?

Stainless steel coil: It is divided into hot-rolled coil and cold-rolled coil according to the processing method, and is divided into SUS420j1, 420j2, 201, 202, 301, 304, 304L, 316, 316L, etc. according to the material. There are many ways to treat surface states, such as ordinary polishing surfaces, 2B surfaces, BA mirrors, 8K mirrors, etc.
