Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A709 Gr 36 bridge steel plate steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This A709 Gr 36 bridge steel plate method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
S960Q steel plate is a high-strength structural steel plate, which is mainly used to manufacture low-temperature-resistant, high-strength key components, construction machinery, and mining machinery structures. General construction and various engineering machinery applications, such as drilling rigs, electric shovels, electric wheel dump trucks, mining cars, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment used in mining and various engineering constructions and other structural parts.
The qualified flat steel has sufficiently high high temperature strength and high temperature plasticity. Therefore, A709 Gr 36 bridge steel plate flat steel is not only required to have high enough normal temperature and instantaneous high temperature tensile strength and plasticity, but also long-term strength and long-term plasticity to ensure long-term safe work at high temperatures, especially under creep leakage conditions. The product thickness is 8-50mm, width 150-625mm, length 5-15m。
For the A709 Gr 36 bridge steel plate construction industry, the largest consumer sector of the steel industry and the least affected industry in the EU this year, it is estimated that A709 Gr 36 bridge steel plate steel consumption will account for 35% of the EU steel consumption market this year. Uestf forecasts that the output of the construction industry will decline by 5.3% in 2020 and rise by 4% in 2021.
