摘要： PROBLEM TO BE SOLVED: To provide an estimation method capable of accurately and easily estimating a corrosion state when estimating the corrosion state of a steel material in a predetermined composition in a predetermined atmospheric environment. SOLUTION: The estimation method comprises: a steel corrosion index calculation process of calculating the steel corrosion index of the steel material from the amount of two or more elements included in the steel material to be an estimation object; an environmental corrosion index calculation process of calculating the environmental corrosion index of the atmospheric environment from two or more environmental factors indicating the state of the atmospheric environment in which the steel material to be the estimation object is used; and an estimation process of estimating the corrosion state of the steel material to be the estimation object, for a boundary obtained from the relationship of the steel corrosion index and the environmental corrosion index calculated beforehand and the corrosion state, depending on in which area divided by the boundary the steel material corrosion index and the environmental corrosion index are positioned.

摘要： PURPOSE: A steel coating material for a ballast tank with a superior coating-swelling resistance, and a ballast tank and a ship using the same is provided to decrease the speed of corrosion by forming a dense passivation coating on the surface of a substrate. CONSTITUTION: A steel coating material for a ballast tank with a superior coating-swelling resistance comprises C 0.01~0.30 weight%, Si 0.01~2.0 weight%, Mn 0.01~2.0 weight%, Al 0.005~0.10 weight%, S 0.010 weight% or less, Cu 0.01~5.0 weight%, Ni 0.01~5.0 weight%, and the rest Fe and inevitable impurities. The surface roughness of at least the part the coating steel material in which coating is laminated 15~80μm.

摘要： A ship structural steel material with excellent corrosion resistance is provided to achieve practical use without using a coating device or a corrosion protection device. A ship structural steel material with excellent corrosion resistance comprises C: 0.01 ~ 0.20 wt%, Si: 0.1 ~ 0.5 wt%, Mn: 0.6 ~ 1.8 wt%, P: 0.0005 ~ 0.02 wt%, S: 0.0005 ~ 0.01 wt%, Al: 0.01 ~ 0.10 wt%, Ni: 0.1 ~ 0.5 wt%, Cr: 0.01 ~ 0.3 wt%, Ti: 0.001 ~ 0.05 wt%, Ca: 0.0003 ~ 0.004 wt%, N: 0.0020 ~ 0.008 wt%, the rest iron and impurities. C is added in order to secure the strength of the steel material. Si is added in order to secure deoxidation and strength. P is added in order to produce phosphate and improve the corrosion resistance. Ni is added in order to suppress etch response occurring in the anti-corrosion coating film state. Cr is added in order to densify rust and improve the corrosion resistance. Ti is added in order to densify the rust generated in the chloride corrosion environment and to suppress acceleration of corrosion on the defective film part. Ca is added in order to lessen pH reduction of the corrosion leading end and improve the corrosion resistance.
