Steel is a material of various shapes, sizes and properties required by steel ingots, billets or steel products through pressure processing.
Steel is widely used and has a variety of varieties. According to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products, and can be divided into heavy rails, light rails, large steels, medium steels, small steels, and steel cold-formed steels. , High-quality section steel, wire rod, medium and thick steel plate, thin steel plate, silicon steel sheet for electrical purposes, strip steel, seamless steel pipe, welded steel tube, metal products and other varieties.
Steel can be divided into the following types according to the use
1. Structural steel
(1) Structural steel for construction and engineering is referred to as construction steel, which refers to steel used to make metal structural parts in buildings, bridges, ships, boilers or other projects. Such as carbon structural steel, low alloy steel, reinforced steel, etc.
(2) Structural steel for machinery manufacturing refers to 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-cut structural steel, spring steel, rolling bearing steel, etc.
2.Tool Steel
Generally used in the manufacture of various tools, such as carbon tool steel, alloy tool steel, high-speed tool steel, etc. According to the application, it can be divided into cutting tool steel, die steel and measuring tool steel.
3.Special Steel
Steel with special properties, such as stainless acid-resistant steel, heat-resistant and skin-resistant steel, high-resistance alloy, wear-resistant steel, magnetic steel, etc.
4.Professional steel
This refers to steel for professional use in various industrial sectors, such as steel for automobiles, steel for agricultural machinery, steel for aviation, steel for chemical machinery, steel for boilers, steel for electrical engineering, steel for welding rods, etc.
5.According to the quality of steel
(1) High-quality carbon structural steel, alloy structural steel, carbon tool steel and alloy tool steel, spring steel, bearing steel, etc.
(2) After the steel number, the symbol "A" is usually added for identification.
