Patterned Alloy Steel Plate

Short Description:

The steel plate with pattern on the surface is called the pattern plate, the English name is diamond plate. The pattern is a mixed shape of lentil, rhombus, round bean, and oblate. The lentil shape is the most common in the market. Places of production: Laiwu Steel, Rizhao, Benxi Iron and Steel, Shougang, Ninggang, Meishan Iron and Steel, Anshan Iron and Steel, Taiyuan Iron and Steel, Beitai, etc.

concrete application

The checkered plate has many advantages such as beautiful appearance, anti-skid, strengthening performance, saving steel and so on. It is widely used in transportation, construction, decoration, floor surrounding equipment, machinery, shipbuilding and other fields. Generally speaking, the user does not have high requirements on the mechanical properties and mechanical properties of the checkered plate, so the quality of the checkered plate is mainly manifested in the pattern formation rate, the pattern height, and the pattern height difference. The common thicknesses on the market range from 2.0-8mm, and the common widths are 1250 and 1500mm.

Classification by thickness
Thin steel plate <4 mm (the thinnest 0.2 mm), thick steel plate 4-60 mm, extra-thick steel plate 60-115 mm. The width of the thin plate is 500-1500 mm; the width of the thick plate is 600-3000 mm. The steel type of thick steel plate It is basically the same as the thin steel plate. In terms of products, in addition to bridge steel plates, boiler steel plates, automobile manufacturing steel plates, pressure vessel steel plates and multi-layer high-pressure vessel steel plates, which are purely thick plates, some types of steel plates such as automobile beam steel plates (thickness 2.5-10 mm), pattern Steel plates (thickness 2.5-8 mm), stainless steel plates, heat-resistant steel plates, etc. are crossed with thin plates. 2. The steel plate is divided into hot-rolled and cold-rolled according to rolling.

Classified by purpose
(1) Bridge steel plate (2) Boiler steel plate (3) Shipbuilding steel plate (4) Armor steel plate (5) Automobile steel plate (6) Roof steel plate (7) Structural steel plate (8) Electrical steel plate (silicon steel sheet) (9) Spring steel plate ( 10) Other

Classified by structure
1. Steel plate for pressure vessel: Use capital R to indicate at the end of the grade. The grade can be expressed by yield point or carbon content or alloying elements. Such as: Q345R, Q345 is the yield point. Another example: 20R, 16MnR, 15MnVR, 15MnVNR, 8MnMoNbR, MnNiMoNbR, 15CrMoR, etc. are all represented by carbon content or alloying elements.
2. Steel plate for welding gas cylinders: Use capital HP to indicate at the end of the grade, and its grade can be expressed by yield point, such as: Q295HP, Q345HP; it can also be expressed with alloying elements, such as: 16MnREHP.
3. Steel plate for boiler: Use lowercase g to indicate at the end of the brand name. Its grade can be expressed by yield point, such as: Q390g; it can also be expressed by carbon content or alloying elements, such as 20g, 22Mng, 15CrMog, 16Mng, 19Mng, 13MnNiCrMoNbg, 12Cr1MoVg, etc.
4. Steel plates for bridges: Use lowercase q to indicate at the end of the grade, such as Q420q, 16Mnq, 14MnNbq, etc.
5. Steel plate for automobile beam: Use capital L to indicate at the end of the grade, such as 09MnREL, 06TiL, 08TiL, 10TiL, 09SiVL, 16MnL, 16MnREL, etc.

1. The width of the steel plate is 600~1800mm, and the grade is 50mm; the length is 2000~12000mm, and the grade is 100mm.
2. The height of the pattern is not less than 0.2 times the thickness of the substrate. The size in the picture is not used as the basis for finished product inspection.
3. The steel grades for steel plates are in accordance with GB/T700, GB/T712, and GB/T4171.
4. The mechanical properties of steel plates are not guaranteed. When the buyer has requirements, it can be agreed by both parties in accordance with relevant standards.
5. The steel plate is delivered in a hot rolled state.

Related standards

According to the national standard GB/T 3277 for patterned steel plates, the pattern height should be greater than or equal to 20% of the thickness of the substrate.
