Abstract
The invention discloses a hydrogen sulfide corrosion resistant hardened and tempered high-strength steel plate for an offshore drilling platform. The steel plate consists of the following chemical components in percentage by weight: 0.13%-0.15% of C, 0.15%-0.35% of Si, 1.10%-1.30% of Mn, 1.20%-1.25% of Ni, less than or equal to 0.012% of P, less than or equal to 0.003% of S, 0.020%-0.050% of Al, 0.020%-0.030% of Nb, 0.030%-0.040% of V, 0.015%-0.02% of Ti, 1.00%-1.10% of Cr, 0.40%-0.50% of Mo, 0.0005%-0.0015% of B, less than or equal to 0.25% of Cu, and the balance Fe and inevitable impurities. A production method comprises the processes of heating, rolling and thermal treatment. The steel plate produced by the production method has the characteristics of being uniform in component and internally compact, has a good structure, good comprehensive properties, good hydrogen sulfide corrosion resistance and good welding performance, and the performances of the steel plate completely meet operating requirements of the hydrogen sulfide corrosion resistant hardened and tempered high-strength steel plate for the offshore drilling platform.
