Abstract
The present invention provides a method and compositions useful for inhibiting corrosion of a corrodible metal resulting from contact of water and air with the metal. In this method, a stannous salt and a hydrocarbyl substituted succinimide of a polyethylene polyamine, separately or in combination, are added to the water in a minor amount and reduce corrosion of the metal to a substantially low rate.
