An object of the present invention is to provide a corrosion-resistant steel material for a bulk cargo ship, which exhibits excellent long-term corrosion resistance even in a severe corrosive environment caused by a bulk cargo containing S, and can be suitably used as a structural member of a bulk cargo ship. It is an object to provide a hold for a bulk carrier constructed using steel. SOLUTION: In mass%, C: 0.04 to 0.30%, Si: 0.28 to 0.60%, Mn: 0.1 to 2.0%, P: 0.010 to 0.040 %, S: 0.003 to 0.025%, Al: 0.010 to 0.10%, Cu: 0.10 to 1.0%, Ni: 0.10% or less (excluding 0%), N: 0.0030 to 0.010% is contained, the balance is made of Fe and inevitable impurities, CP1 is 0.10 or more, and CP2 is 0.80 to 7.00.
