Hold for corrosion-resistant steel of coal ship or coal and ore combination carriers

摘要

PROBLEM TO BE SOLVED: To provide a corrosion-resistant steel for a hold of a coal carrying vessel or a coal/ore carrying vessel, which does not undergo corrosion after removal of a coating film therefrom under an environment in which drying and humidification are repeated and the pH value is low.;SOLUTION: A corrosion-resistant steel for a hold of a coal carrying vessel or a coal/ore carrying vessel is characterized in that the steel has a component composition containing, by mass, 0.01 to 0.20% of C, 0.01 to 0.50% of Si, 0.1 to 2.0% of Mn, 0.025% or less of P, 0.035% or less of S, 0.005 to 0.10% of Al, 0.01 to 0.5% of Sn, 0.001 to 0.1% of Ta, with the remainder being Fe and unavoidable impurities.;COPYRIGHT: (C)2014,JPO&INPIT
