How to optimize quality of 1.8933 equivalent

S235JR grade is actively used to implement civil engineering solutions.
Steel structures are made from S235JR steel for the construction of industrial and residential facilities, parts of power transmission towers, elements of equipment, offshore structures, oil and gas platforms, automobile bridges and other structures. S235JR steel plate can be welded without restrictions, without subsequent heat treatment and without heating; however, note that as the product thickness increases, so does the risk of cold cracks.

1.8933 equivalent, 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 1.8933 equivalent 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 1.8933 equivalent steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
