Plate Steel

It is a flat-shaped steel that is poured in molten steel, cooled and then suppressed.

The plate is flat-shaped, rectangular, and can be rolled directly or cut from wide steel strips.

The steel plate is divided by thickness, the thin steel plate is 4 mm (thinnest 0.2 mm), the medium thick steel plate 4~60 mm, the special thick steel plate 60~115 mm.

The steel plate is divided by rolling, hot and cold rolled.

The width of the sheet is 500~1500 mm, and the thick width is 600~3000 mm. The thin plate is divided by grade steel, high quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resisting steels, bearing steel, silicon steel and industrial pure iron sheet, etc. according to the professional use, has the oil barrel board, the enamel board, the bulletproof board and so on, according to the surface coating coating, has galvanized sheet, tin-plated sheet, lead-plated sheet, plastic composite steel plate.


Thickness

Thick steel plates are generally the same as those of thin steel. In all aspects of the product, in addition to bridge steel plate, boiler plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate and other varieties are purely thick plate, some varieties of steel plate such as car girder (thickness 2. $number mm), pattern steel plate (thickness 2. $number mm), stainless steel plate, heat-resisting plate and other varieties are the same sheet.

In addition, the steel plate also has a material said, not all the steel plate is the same, the material is different, the steel plate used in the place, also different.

 

Properties of Alloy Steels

With the development of science and technology and industry, higher requirements for materials, such as higher strength, high temperature resistance, high pressure, low temperature, corrosion resistance, wear and other special physical and chemical properties of the requirements, carbon steel can not fully meet the requirements.


Lack of Carbon Steel

(1) Low hardenability. In general, the maximum quench diameter of carbon steel is only 10mm-20mm.

(2) The strength and yield are relatively low. such as ordinary carbon steel Q235 steel マピ 235MPa, and low alloy structural steel 16Mn マピ is 360MPa above. The マピ/マッ of 40 steel is only 0.43, far below the alloy steel.

(3) Poor tempering stability. Due to poor tempering stability, in order to ensure the high strength of carbon steel in the process of tempering, the toughness of the steel is low, so that the high tempering temperature is low, so the synthetic mechanical properties of carbon steel are not high.

(4) Can not meet the special performance requirements. Carbon steel in anti-oxidation, corrosion resistance, heat resistance, low temperature, wear resistance and special electromagnetic properties are often poor, can not meet the needs of special use performance.


Classification of Alloy Steels

According to the content of alloying elements, 

Low alloy steel (total alloying elements less than 5%),

Medium Alloy Steel (total alloying elements 5%-10%)

High alloy Steel (total alloying elements are higher than 10%).


According to the main alloying elements contained in the

Chromium Steel (CR-FE-C)

Nickel (CR-NI-FE-C)

Manganese Steel (c)

Silicon Manganese Steel (SI-MN-FE-C)


According to the small specimen normalizing or casting structure, divided into

Pearlite Steel

Martensitic Steels

Ferritic Steel

Austenitic Steel

Laigang Steel


Classification by Purpose

Alloy structural steels

Alloy tool Steel

Special can Steel
