A572 gr42 steel plate is a kind of main precision steel structure and normalizing steel. A514 grade P high strength steel plate, ASTM A572 gr42, 50, 55, 60, 65 is a kind of high strength low alloy steel plate, which is widely used in factory construction, general buildings and various construction machinery, such as mining and various construction drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, hydraulic supports, mining machinery and other structures.
The A514 grade P high strength steel plate 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 A514 grade P high strength steel plate 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 A514 grade P high strength steel plate 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 A514 grade P high strength steel plate size.
Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for A514 grade P high strength steel plate and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
