| Abstract: | A study was performed on TMCP (thermo-mechanical control process) - manufactured high-tensile steel plates with yield point of 40 kgf/mm2 (YP40), which were recently developed for use in ship production and whose ease of shop fabrication is almost equal to that of the well-proven ship high-tensile steel plates (HT50) with yield points at 32 and 36 kgf/mm2 levels. The authors' study addressed the performance required of the YP40 TMCP high-tensile steel for ship applications, including strength characteristics of base metal and high-heat-input welded joints, and also shop fabrication methods suitable to this material. |
