acier S690QL equivalent sheet properties and usage

The common uses of acier S690QL equivalent, boiler and pressure vessel steel plate are as follows. First, make boilers and pressure vessels. Boiler and pressure vessel steel plate not only has a certain strength, but also has a certain ability to withstand impact. The boiler and pressure vessel steel plate should be resistant to abrasion and high temperature. Second, the boiler and pressure vessel steel plate is used to make spherical tank, oil gas tank, liquefied gas tank and other tanks. The boiler and pressure vessel steel plate should have the characteristics of corrosion resistance and pressure resistance.

The acier S690QL equivalent plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The acier S690QL equivalent products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This acier S690QL equivalent production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate acier S690QL equivalent size.

Classification of acier S690QL equivalent, steel plate, including strip steel:
1. Classified by thickness: (1) thin plate (2) medium plate (3) thick plate (4) extra thick plate
2. Classification by production method: (1) hot rolled steel plate (2) cold rolled steel plate
3. Classification according to surface characteristics: (1) galvanized sheet (hot galvanized sheet, electro galvanized sheet) (2) tin plate (3) composite steel plate (4) color coated steel plate
4. Classification by use: (1) bridge steel plate (2) boiler steel plate (3) shipbuilding steel plate (4) armored 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) others
