8*2400*10000 A387 grade 22 class 1 pressure vessel steel sheet MS Mild Steel Plates

The quality of A387 grade 22 class 1 pressure vessel steel sheet shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of A387 grade 22 class 1 pressure vessel steel sheet buyer, such as packaging, delivery time, etc.. On the basis of the quality of A387 grade 22 class 1 pressure vessel steel sheet in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of A387 grade 22 class 1 pressure vessel steel sheet and certain performance limit of A387 grade 22 class 1 pressure vessel steel sheet, etc.

Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, A387 grade 22 class 1 pressure vessel steel sheet weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.

S355J2 steel plate A387 grade 22 class 1 pressure vessel steel sheet rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the A387 grade 22 class 1 pressure vessel steel sheet single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
