| Abstract: | The datum of high strength beam plate produced in trial scale were analyzed, the results showed that the low - carbon, low - alloy steel could meet the strength and toughness requirements of steel 506L and 590L after addition of some trace elements. In this paper, the trace elements Nb, V, Ti could result in grain refining, precipitation strengthening, solid solution strengthening , so as to increase the strength of the steel. |
