What are the characteristics of medium and thick plate, ASTM A514 alloy steel plate? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, ASTM A514 alloy steel plate is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.

According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron ASTM A514 alloy steel plate production excluding China was 36.309 million tons, a year-on-year decrease of 11%.
Oxygen is a harmful element in ASTM A514 alloy steel plate steel. With the increase of oxygen content, the strength of ASTM A514 alloy steel plate steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of ASTM A514 alloy steel plate steel.
