摘要（英）：

The invention belongs to the metallurgical field, relating to seawater corrosion-resisting steel and a manufacturing process thereof. The molten steel of the seawater corrosion-resisting steel comprises the following chemical compositions in weight percentage: 0.070 to 0.120 percent of C, 0.500 to 0.650 percent of Mn, 0.000 to 0.020 percent of P, 0.000 to 0.015 percent of S, 0.250 to 0.450 percent of Si, 0.800 to 1.200 percent of Cr, 0.200 to 0.300 percent of Mo, 0.450 to 0.600 percent of Alt, 0.006 to 0.02 percent of Ti, the balance being Fe. The process comprises working procedures such as revolving furnace smelting, RH refining, LF refining, wide slab continuous casting and jobbing sheet rolling mill rolling, etc. The invention resolves a series of difficulties presently existing in the production of the seawater corrosion-resisting steel, and has obvious effect on the mass production of the seawater corrosion-resisting steel, thereby being capable of creating desirable economic value for enterprises.
