摘要
PROBLEM TO BE SOLVED: To provide a steel structure good in the water resisting adhesion of coating even in the case of being used over a long period in a wet environment and good in cathode peeling resistance even in the case of being applied with electric protection and to reduce the cost of the steel structure as well.;SOLUTION: By applying coating on the surface of low alloy steel contg. chromium of ≥0.5 wt.%, preferably of 0.5 to 5 wt.% so as to control the insulating resistance to ≥104Ω.m2, coated steel good in the water resisting adhesion of the coating even in the case of being used over a long period in a wet environment and also good in cathode peeling resistance even in the case of being applied with electric protection is partially adapted. Moreover, by adding at least one kind of 0.1 to 2 wt.% molybdenum and 0.1 to 1.5 wt.% aluminum, the alloy good in water resisting adhesion and cathode peeling resistance and also satisfying the conditions such as mechanical properties and toughness can be obtd.;COPYRIGHT: (C)2000,JPO
