Pressure Vessel Alloy Steel Plate
It is a large category of steel plate-container plate With special composition and performance
It is mainly used as a pressure vessel. According to different purposes, temperature and corrosion resistance, the material of the vessel plateshould be different.
Heat treatment: hot rolling, controlled rolling, normalizing, normalizing + tempering, tempering + quenching (quenching and tempering)
Such as: Q345R, 16MnDR, 14Cr1MoR, 15CrMoR, 09MnNiDR, 12Cr2Mo1R, Q345R (HIC), 07MnCrMoVR, 13CrMo44, 13MnNiMo54
The above are Chinese brands, and there are many foreign brands.
Such as: SA516Gr60, SA516Gr65, SA516Gr70, P355GH, P265GH and so on.
Comparison of main contents of new and old standards for steel plates for boilers and pressure vessels
Widely used in petroleum, chemical industry, power station, boiler and other industries, used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied oil and gas cylinders, Users are very satisfied with the equipment and components such as high-pressure water pipes of hydropower stations and turbine volutes. Wusteel has established a special boiler steel plate scientific research department, which is completely equivalent to adopting foreign standards to organize the production of boiler steel plates of various standards, brands and specifications.
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.
