| Abstract: | The X52 plate steel is the one of microallogyed with niobinum andtitanium by rolling and cooling under some controlled conditions, the higher purity and less sulfur contents are got through the technological improvement in steel making. Also by the formulation of chimical composition and the control of roll down,the requisite balance of strength and toughness can be achieved. |
