Definitions

  • HIC hydrogen-induced cracking
  • Patent Literature 1 a steel is disclosed in which the hydrogen-induced cracking resistance is improved by suppressing the segregation degree of Mn, Nb, and Ti of the plate thickness center part. According to this method, although the HIC property of the center segregation part can be improved, the inclusion of the portion other than the center segregation part is not controlled sufficiently, and therefore it is considered to be hard to suppress cracking of the portion other than the center segregation part.
  • the inclusion composition that became the origin of generation of HIC including the fine HIC described above was investigated. More specifically, the microstructure was observed with respect to the steel plate for which the HIC test (NACE test) described in the example shown below was executed. Also, the Ca concentration of the inclusion observed was obtained. This Ca concentration in the inclusion is the rate (mass%, hereinafter shown merely as %) of Ca relative to the componential composition constituting the inclusion and excluding O and N. The rate (%) of the inclusions that became the origin of generation of HIC out of the inclusions with 50% or more of the Ca concentration in the inclusion and the rate (%) of the inclusions that became the origin of generation of HIC out of the inclusions with 20% or less of the Ca concentration in the inclusion were obtained respectively. The result is shown in Fig.
  • the Cmax/Cave is preferably 1.19 or less, more preferably 1.18 or less, and still more preferably 1.15 or less.
  • the lower limit is approximately 1.00 at which the Ca amount of the steel plate surface layer part and inside the steel becomes equal.
  • N is an element precipitating as TiN in the steel microstructure, suppressing coarsening of the austenitic grain of the HAZ part, promoting the ferritic transformation, and improving the toughness of the HAZ part.
  • N should be contained by 0.001% or more.
  • N amount is preferably 0.003% or more, and more preferably 0.0040% or more.
  • N amount is preferably 0.008% or less, and more preferably 0.0060% or less.
  • O oxygen
  • O amount should be 0.0045% or less, is preferably 0.0030% or less, and more preferably 0.0020% or less.
  • V is an element effective in improving the strength, and, in order to secure this effect, it is preferable to contain V by 0.003% or more, and more preferably 0.010% or more.
  • V content exceeds 0.1%, the weldability and the base plate toughness deteriorate. Therefore, V amount is preferably 0.1% or less, and more preferably 0.08% or less.
  • the present application is to claim the benefit of the right of priority based on Japanese Patent Application No. 2013-073310 applied on March 29, 2013 . Entire contents of the description of Japanese Patent Application No. 2013-073310 applied on March 29, 2013 are incorporated by reference into the present application.
  • the steel plates related to the present invention are excellent in the hydrogen-induced cracking resistance and the toughness, they are used suitably to a line pipe for transportation, a pressure vessel, a storage tank and the like of natural gas and crude oil.
