Composition consisting essentially of a hydroxylamine compound having the general formula ##STR2## where R.sub.1, R.sub.2, and R.sub.3 are either the same or different and selected from the group consisting of hydrogen, lower alkyl and aryl, and the water-soluble salts thereof, and a second neutralizing amine.
Method of inhibiting corrosion in steam condensate lines, comprising maintaining in solution therein, 0.001 to 100 ppm of a hydroxylamine compound having the general formula:
- ##STR3## wherein R.sub.1, R.sub.2, and R.sub.3 are either the same or different and selected from the group consisting of hydrogen, lower alkyl and aryl, and the water-soluble salts thereof, and 1 to 1,500 ppm of at least one additional neutralizing amine.
