There are three main methods of A387 grade 12 class 1 pressure vessel steel sheet steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.S355NL steel plate is under EN10111 standard. We can regard A387 grade 12 class 1 pressure vessel steel sheet, S355NL steel plate as Fine-grain structural steels, normalised rolled. S355NL steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel S355NL is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and BS:55EEManagement concept: abide by laws, regulations and social norms.
