A572 Gr 50 high strength steel, S355ML steel plate is hot-rolled weldable fine grain structural steel, which belongs to low alloy high strength steel. It is a flat rolled product with thickness less than 120mm and a long product with thickness less than or equal to 150mm. S355ML steel is used in the load-bearing parts of low temperature welding structures such as bridges, sluices, storage tanks, water supply tanks, etc.
A572 Gr 50 high strength steel, Hot-rolled steel coils are made of steel billets, which are made into strip steel by the rough rolling mill and the finishing mill after heating. The hr steel strip from the rolling mill behind the finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel coil by the coiler. The cooled steel coil will undergo different processes according to the different needs of users, and is processed into steel plates, flat coils and slit steel strip products.
Since the beginning of this year, the global A572 Gr 50 high strength steel steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global A572 Gr 50 high strength steel steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
