(1) in the development of S355JR  steel  plate, it is necessary to refine the treatment process and ensure the addition of a number of microalloying elements for strengthening. (2) control of rolling and cooling temperature is the key to the development of rolling, not only to control rolling and cooling, but also to ensure the thickness of the re-rolling  S355JR steel plate , after the temperature of the pressing rate is greater than 60%. (3) the control proportion of  S355JR steel plate   microalloying elements should be scientific and reasonable. (4) after the development of S355JR steel plate, the performance is stable, with the conditions of mass production.

S235JR is a European designation for steel that is better known in Lebanon as St 37-2 according to German standards (DIN), or as E 24-2 according to French standards NF (AFNOR). As for the equivalence in American standards, this steel may be referred to as ASTM A 570 grade 36 (ASTM 570/A 570 M-98, 2000) when sheets or strips of less than 6mm are considered, or to ASTM A 36 Grade 36 (ASTM A36/A 36 M-93a, 1997), or ASTM A 709 Grade 36 (ASTM 709/A 709 M93-a, 1997) when considering other standard shapes and sheet thickness. Table 1 shows a list of corresponding former European designations for this type of steel .
