The application of astm a573 grade 58 high strength structural steel sheet is expanding

Low welding crack sensitivity high-strength steel plate, today mainly introduces Q620CF, with three grades C, D, E. The grades of low-welding crack sensitivity high-strength steel plate: Q460CFC, Q460CFD, Q460CFE, Q500CFC, Q500CFD, Q500CFE, Q550CFC, Q550CFD , Q550CFE, Q620CFC, Q620CFD, Q620CFE, Q690CFC, Q690CFD, Q690CFE, astm a573 grade 58 high strength structural steel sheet, Q800CFE. It is mainly used for the production of hydropower penstocks, construction machinery, railway vehicles, bridges, high-rise and large-span buildings that require high weldability.

Compared with ordinary carbon steel plate, manganese steel plate has the following advantages. First, astm a573 grade 58 high strength structural steel sheet, manganese steel plate is convenient for welding and processing. Second, manganese steel plate has good heat resistance, and can be processed into various containers. Third, manganese steel plate has good toughness. It is not easy to fracture and has long service life. Fourth, the performance of manganese steel plate is good at low temperature. It will not fracture because of temperature, so it can be used in cold areas.

The visual inspection (VI) or visual detection method is to scan the surface of the steel plate through a machine vision system (CCD line camera), convert the captured target into an image signal, and send it to a dedicated image astm a573 grade 58 high strength structural steel sheet processing system, which converts it into a digital signal based on pixel distribution and brightness, color and other information. The system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on the spot according to the result of the discrimination. Visual detection method can achieve online high-speed detection for the astm a573 grade 58 high strength structural steel sheet steel plate.
