| titleOfInvention | Thick steel sheet excellent in heat-affected zone toughness of ultra-high heat input welding and its manufacturing method |
| abstract | (57) [Summary] [Problem] We propose a thick steel plate excellent in the toughness of the heat affected zone of ultra-high heat input welding with heat input exceeding 300 kJ / cm and a manufacturing method thereof. SOLUTION: The molten steel is deoxidized by adding Si and / or Mn to adjust the amount of dissolved oxygen to 0.0030 to 0.0120%, and then REM is added to make C: 0.03 to 0.18%, Si: 0.05 to 0. 40%, Mn: 0.5 to 3.0%, P: 0.03% or less, S: 0.0005 ~ 0.0060%, REM: 0.0030 ~ 0.0200%, O: 0.0070% or less, Al and Ti are each limited to 0.004% or less, then cast into steel material, hot-rolled to thickness Steel plate. Thus, a structure in which REM sulfide, oxide, and oxysulfide particles having an average particle size of 10 μm or less and Mn oxide, sulfide, and oxysulfide particles having an average particle size of 1 μm or less are dispersed is obtained. Become. In order to further improve the toughness of the heat affected zone, REM should be added to REM containing 40 to 70% by mass of REM. This may be done with dilute alloys or REM containing mixtures. |
