What are the common types of steel?

1. According to chemical composition, there are (1) low carbon steel (2) medium carbon steel (3) high carbon steel. Carbon steel refers to an iron-carbon alloy containing a small amount of manganese, silicon, sulfur, phosphorus and other elements in addition to iron and carbon, which is different because of its different chemical composition.

According to the different carbon content, it can be divided into steel and pig iron. Among them, the iron-carbon alloy with carbon content of 0.03% ~ 2% is called steel, and the iron-carbon alloy with carbon content of 2% ~ 4.3% is called pig iron. The alloy steel includes (1) medium alloy steel (2) and (3) high alloy steel.

Three, steel carbon exists in different forms, which can be divided into white iron, gray cast iron and ductile iron.

Four, according to the smelting equipment points (1) converter steel (2) open hearth steel (3) electric furnace steel.

Five, according to the quality of steel (1) ordinary steel (2) high-quality steel (3) high-quality steel.

Six, according to the steel structure is divided into (1) structural steel for construction and structural steel for engineering (2) structural steel for machinery manufacturing.

Seven, professional steel is divided into (1) cast steel (2) forged steel (3) hot rolled steel (4) cold rolled steel (5) cold drawn steel.

Eight, tool steel is generally used to manufacture various tools, such as carbon tool steel, alloy tool steel, high-speed tool steel, etc. According to the use of steel, it can be divided into cutting tool steel, die steel and measuring tool steel.

Nine, special steel steel with special properties, such as stainless acid-resistant steel, heat-resistant steel, high-resistance alloy, wear-resistant steel, magnetic steel and so on. The above is the introduction of Changge Steel to ordinary steel and steel classification. Stay tuned for more information.
