What are the functions of different types of steel?

structural steel

(1) Structural steel for construction and engineering, abbreviated as construction steel, refers to steel used for making metal structural components in buildings, bridges, ships, boilers, or other engineering projects. Such as carbon structural steel, low-alloy steel, steel reinforcement steel, etc.

(2) Structural steel used in mechanical manufacturing refers to the steel used to manufacture structural parts on mechanical equipment. This type of steel is basically high-quality steel or high-grade high-quality steel, mainly including high-quality carbon structural steel, alloy structural steel, easy cutting structural steel, spring steel, rolling bearing steel, etc

chisel tool steel

Generally used for manufacturing various tools, such as carbon tool steel, alloy tool steel, high-speed tool steel, etc. According to their purposes, they can be divided into cutting tool steel, mold steel, and measuring tool steel.

special steel

Steel with special properties, such as stainless acid resistant steel, heat-resistant non peeling steel, high resistance alloy, wear-resistant steel, magnetic steel, etc.

Professional steel

This refers to steel used for professional purposes in various industrial sectors, such as automotive steel, agricultural machinery steel, aviation steel, chemical machinery steel, boiler steel, electrical steel, welding rod steel, etc.

Classified by the quality of steel

High quality carbon structural steel, alloy structural steel, carbon tool steel and alloy tool steel, spring steel, bearing steel, etc

After the steel grade, the symbol "A" or the Chinese character "high" is usually added for identification.
