Katalor supply the best S355JR steel plate

(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.
