<P>PROBLEM TO BE SOLVED: To provide a corrosion resistant steel material rigged for boats and ships, which exhibits excellent corrosion resistance in a seawater-splashing environment or an environment in which the deterioration is significantly caused by ultraviolet rays. <P>SOLUTION: The corrosion resistant steel material rigged for boats and ships is characterized in that a coating is applied on the surface of a steel material which has a composition containing, by mass, 0.01-0.2% of C, 0.01-2.5% of Si, 0.1-2.0% of Mn, <0.03% of P, <0.01% of S, 0.005-0.3% of Al, and 0.001-0.008% of N, and further containing one or more kinds, in which Cr is <0.02% and which are selected from 0.01-1.0% of Cu, 0.005-1.0% of W, 0.005-1.0% of Mo, and 0.001-0.3% of Sn, with the balance comprising Fe and inevitable impurities. <P>COPYRIGHT: (C)2013,JPO&INPIT |
