There are many kinds of steel. In order to facilitate production, use and management, they can be classified according to the following methods

1. Classification by chemical composition

According to chemical composition, steel can be divided into carbon steel and alloy steel. Carbon steel is divided into low carbon steel, medium carbon steel and high carbon steel according to carbon content. Alloy steel is divided into low alloy steel, medium alloy steel and high alloy steel according to the content of alloy elements

2. Classification by quality

The quality of steel is divided by the content of sulfur and phosphorus. According to the content of sulfur and phosphorus, steel can be divided into ordinary quality steel, high-quality steel, high-grade high-quality steel and super high-quality steel

3. Classification according to smelting method

According to different steelmaking furnaces used for smelting, steel can be divided into open hearth steel, converter steel and electric furnace steel

4. Classification according to metallographic structure

In the annealing structure, the steel can be divided into hypoeutectoid steel, eutectoid steel and hypereutectoid steel. According to the normalized structure, the steel can be divided into pearlitic steel, bainitic steel, martensitic steel, ferritic steel, austenitic steel and ledeburite steel

5. Classification by use

The steel can be divided into structural steel, tool steel and special performance steel according to the use
