(I)define

 

Steel plate is a flat steel made by pouring molten steel, cooling it, and pressing it. It can present a rectangle, usually formed by direct rolling or cutting from a wide steel strip

(II)Classification

①According to thickness, steel plates can be divided into thin steel plates and thick steel plates.

 

The thickness of thin steel plates ranges from 0.2 millimeters to 4 millimeters, while the thickness of thick steel plates ranges from 4 to 60 millimeters.

 

The thickness of extra thick steel plates can reach 60 to 115 millimeters

 

 

②Steel plates can be divided into hot rolling and cold rolling according to the rolling method. 

 

Hot rolled steel plates are produced through high-temperature rolling, with a rough surface but high strength; 

 

Cold rolled steel plates undergo cold processing, resulting in a smooth surface and higher precision

 

 

③Differences in Steel Plate Materials，In terms of grades, Q195, Q215, Q235, Q255, and Q275 respectively represent the grades of steel; Q represents the first letter of the Chinese Pinyin for the yield point of steel, with 195, 215... indicating the numerical value of the yield point. In terms of chemical composition, the larger the grades Q195, Q215, Q235, Q255, and Q275 of low-carbon steel, the higher the carbon and manganese content, and the more stable its plasticity

 

In addition, steel plates can be divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel, and industrial pure iron thin plates according to their applications.

 

(III)purpose of steel plates

 

In industrial applications, steel plates have a wide range of usage scenarios. 

 

For example, thin steel plates are often used to make oil drums, enamel products, etc; 

 

Thick steel plates are suitable for building structures and bridge construction. 

 

Stainless steel plates are commonly used in the manufacturing of ships, chemical equipment, etc. due to their corrosion resistance.
