The SA514 grade P steel material application details

Large-thickness SA514 grade P steel material, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.

Q690D steel belongs to high-strength welded structural steel. Among them, Q represents the yield strength, 690 represents the yield strength value, and D represents the grade of the steel plate. The quality grades of common Q690 series steel are A, B, C, D, E. The impact of grade D steel plate is -20°C. Q690D steel can be called a low temperature resistant high strength steel with a yield strength of 690Mpa.

EU-28 countries produced 38.29 million mt of SA514 grade P steel material, crude steel in the first quarter down by ten percent year on year. In the given period, Germany's output was 9.47 million mt. falling by 9.3 percent year on year. Italy's crude steel output was 5.28 million mt, down by 16.2 percent year on year, and France's crude steel output amounted to 3.73 million mt decreasing by 3.6 percent year on year.
