1、 Alloy structural steel

Alloy structural steel is a type of steel that improves its performance by adding different proportions of alloy elements, mainly including low alloy structural steel, high alloy structural steel, light alloy structural steel, etc. Compared with ordinary low-carbon steel, alloy structural steel has significantly improved mechanical properties such as strength, toughness, and wear resistance, and is widely used in mechanical manufacturing, automotive manufacturing, aerospace and other fields.

2、 Tool steel

Tool steel is a highly wear-resistant steel used for manufacturing tools such as molds, cutting tools, measuring tools, and cold stamping dies, typically including carbon steel, alloy steel, high-speed steel, powder metallurgy tool steel, etc. Tool steel is highly valued for its high hardness, toughness, and excellent wear resistance, and is widely used in fields such as mold manufacturing, mechanical processing, and lathe processing.

3、 Stainless steel

Stainless steel is a type of steel with excellent corrosion resistance. Commonly used stainless steels include austenitic stainless steel, martensitic stainless steel, ferritic stainless steel, etc. Stainless steel can maintain its performance in corrosive media such as air, water, acid, and alkali without being affected, and is widely used in the food industry, chemical industry, building decoration and other fields.

4、 Heat resistant steel

Heat-resistant steel refers to a type of steel that can maintain its mechanical and chemical properties in high-temperature environments, usually including ferritic heat-resistant steel, martensitic heat-resistant steel, and austenitic heat-resistant steel. Heat-resistant steel has excellent oxidation resistance, high-temperature strength, and ductility, and is widely used in fields such as oil refining, chemical engineering, aerospace, etc.

5、 Corrosion-resistant steel

Corrosion resistant steel is a type of steel that can maintain its properties unchanged in corrosive media, mainly including ordinary corrosion resistant steel, acid resistant steel, and alkali resistant steel. The main characteristic of corrosion-resistant steel is that it can maintain good corrosion resistance for a long time in strong acid, alkali, and high salt seawater. Widely used in fields such as marine environment, petrochemical industry, environmental protection, and building decoration.

In summary, there are various types of special steel, and each type of steel has its own unique application field and mechanical performance characteristics. Steel plays an important role in modern industry, and different types of special steel have their own unique application value in different fields.
