Abstract
PURPOSE: To insure stability of corrosion product by specifying Cr, Si, Al in steel.
CONSTITUTION: The steel comprises, in the % basis, 0.03W0.1 C, 0.2W4.0 Si, 0.02W1.5 Mn, 0.02 or less S, 0.015 or less P, above 0.1W3.0 Al, 3W13 Cr and the remainder Fe. Herein, C is necessary in order to insure strength but the upper limit is determined in order to insure corrosion resistance. Si is necessary from a standpoint of deaidification as well as forms an Si rich layer in a carbon dioxide gas saturated water environment to enhance corrosion resistance of said steel and the upper limit thereof is defined in an effective range. Because S, P promote corrosion, a content thereof is pref. reduced as possible as low. Al is added in order to form alminum killed steel for grain refining but forms an Al rich layer in a carbon dioxide gas saturated water environment to remarkably control corrosion thereof and the upper limit thereof is defined in an effective range. Cr remarkably increase corrosion control effect of Si, Al and, other than said effect, Cr alone reduces a corrosion speed. Further, when Mo, Ni, W are coexisted with Cr, the aforementioned effects are surprisingly enhanced.
