Abstract
An elongated steel object is covered with a coating layer having 1) an electrode potential exceeding the electrode potential of steel, or 2) a rate of corrosion which is lower than the rate of corrosion of steel and is treated with a corrosion inhibiting composition. This composition includes: A) a carrier of an oily or waxy type; B) active components comprising at least B1) a corrosion-inhibitor in the form of a sulphonate of the group IIA, B2) a co-corrosion-inhibitor, selected from the group consisting of (a) fatty acids, having 6-24 carbon atoms, aromatic acids and naphthenic acids, which acids have the free acid form or the salt form; (b) imidazoline derivatives having a C,alkyl moiety; and (c) C,alkylsuccinic anhydride compounds; as well as mixtures of compounds defined under (a), (b) and (c); and (C) optionally a compound selected from the group consisting of: C1) a water repellent; C2) a synthetic ester derived from a C,alcohol with 1-12 hydroxyl groups and C,fatty acids; and C3) a C,alcohol as well as a mixture of compounds defined under C1), C2) and/or C3).
