Steel products for the building and civil engineering structures with excellent compatibility with the water-based paint

摘要

PROBLEM TO BE SOLVED: To provide a steel material excellent in compatibility with water-based coating materials, which makes a water-based coating applicable to a large size structure by improving corrosion resistance of the steel material itself.;SOLUTION: A steel material contains, by mass, 0.03-0.30% of C, 0.01-1.0% of Si, 0.10-2.0% of Mn, ≤0.03% of P, ≤0.007% of S, and 0.01-0.05% of Sn, and contains one or more selected from among 0.01-0.10% of Cr, 0.05-0.10% of Cu, and 0.05-0.10% of Ni, and further contains one or two selected from among 0.01-0.08% of Mo and 0.01-0.08% of W, and the balance Fe with inevitable impurities.;COPYRIGHT: (C)2013,JPO&INPIT
