Carbon Steel vs Iron

1) What is carbon steel?

In fact, carbon steel (CS/MS seamless pipe) refers to the carbon content in the steel, on which its mechanical properties depend. Generally, steel without alloying elements is also called plain carbon steel or carbon steel, which refers to iron-carbon alloys with a carbon content of less than 2%, while carbon steel also contains a small amount of silicon, manganese, sulfur and in addition to carbon, there are phosphorus. Generally speaking, carbon steel with higher carbon content has higher hardness and strength, but lower ductility.

2) What is iron?

Iron is a chemical element and a commonly used metal, a transition metal. Iron iron, atomic number 26, relative atomic mass 55.847. Iron has many allotropes and is a relatively active metal, ranking before hydrogen in the list of metal active sequences.
At room temperature, iron is not easy to react with non-metallic elements such as oxygen, sulfur and chlorine in dry air, but it reacts violently at high temperature.

3) The difference between carbon steel and iron

1. The difference between carbon steel and iron is the carbon content. Steel is a general term for ferroalloys with a carbon content of 0.02% to 2.04%. The chemical composition of steel varies widely. Steel containing only carbon elements is called carbon steel or ordinary steel; in actual production, steel often contains different alloying elements, such as manganese, nickel, vanadium, etc., according to different uses.

Low carbon steel: the carbon content is generally less than 0.25% (mass fraction);
Medium carbon steel: the carbon content is generally 0.25%~0.60% (mass fraction);
High carbon steel: the carbon content is generally higher than 0.60% (mass fraction).
