| Abstract: | Through controlling carbon equivalent （≤0.42%） reasonably, adding appropriate microalloy element Nb, adopting liquid iron with low sulfur content, LF＋RH refining processes, protection casting technology, TMCP process and normalizing treatment, Handan Steel developed E36-Z35 high strength ship plates successfully. The test results showed that the E36-Z35 hull plates have high strength, good toughness and excellent lamellar tearing resistant ability and welding performance, the NDT temperature achieved minus 65 ℃ by DWTT and the absorbed-in-fracture energy at minus 40 ℃was not less than 34 J, meeting the requirements of the rules of Classification Society fully. |
