Abstract: A method for producing a component made of a steel product coated with an Al—Si protective coating, includes: providing a substrate consisting of a steel produced coated with an Al—Si protective coating, heating the substrate to a temperature T1 such that the Al—Si protective coating is only partially pre-alloyed with Fe of the steel product, cooling the pre-alloyed substrate to room temperature, applying a corrosion protection oil to the surface of the pre-alloyed substrate, wherein the oil consists of a composition containing fatty acid ester, transporting the pre-alloyed substrate to which the oil has been applied, heating the pre-alloyed substrate to which the oil has been applied to a temperature T2 such that the Al—Si protective coating is fully alloyed with Fe of the steel product and the oil is removed without leaving residue, and shaping the re-heated substrate to form the component.

Abstract: The invention relates to an anti-corrosive composition comprising an active material of formula I wherein R is an aliphatic chain of C12 to C20 and n?20; an anti-corrosive pigment, a filler mixture, and a diluent or carrier. The invention also relates to a process for preparing the anticorrosive composition and a metal substrate having a coating comprising the anti-corrosive composition.

Abstract: The invention relates to an oleaginous corrosion-inhibiting coating composition, and the use of said coatings to protect metal from corrosion. The composition comprises, in parts by weight, from about 20 to 40 parts of lubricating oil, 10 to 40 parts of organic solvents, 10 to 30 parts of an inhibitor consisting of sulfonic acid-carboxylic acid metal complexes, effective amounts of at least two different oil soluble antioxidants, effective amounts of at least one water-displacing compound, 10 to 30 parts of at least one alkyl or alkylaryl metal sulfonate and 0.1 to 2.0 parts of at least one phosphoric acid ester and amine salt.

Abstract: A rustproofing composition has superior properties satisfying rustproofing quality requirements and work quality requirements for parts around tires, parts with pockets, and plate-bonded parts, and having volatile organic solvent of not more than 10 mass %. A rustproofing composition has 5 to 60 mass % of the overall composition of at least one kind of heat-polymerized drying oil in which oil having an iodine value of not less than 130 is heat-polymerized, and 1 to 50 mass % of the overall composition of at least one kind of wax selected from natural waxes and synthetic waxes, and/or at least one kind of rustproofing additive dissolved or dispersed in mineral oil type lubricant based oils, synthetic lubricant based materials or liquid saturated-hydrocarbon mixtures vegetable oil based semidrying oils, and vegetable oil based nondrying oils. In the rustproofing composition, nonvolatile content at 105° C. for 3 hours is not less than 90 mass %.

Abstract: The present invention relates to a method for inhibiting high temperature corrosion of corrosion prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of 4-sulfophthalic acid, typically up to 1000 wppm, to the metal surface.

Abstract: Entirely asphaltic, micro-crystalline wax- and aluminum-based coating compositions, which are fully flexible and accommodate any expansion or contraction in steel structures, are prepared from various combinations of components, e.g. those selected from microcrystalline wax, naphthenic and paraffinic oils, oil-soluble alkali-metal sulfonate, gilsonite, linseed oil, naphthenic acid, solvent, a viscosity modifier, aluminum paste, attapulgite, emulsifier, milled cellulose fiber, ground mica, and silica gel, according to a described stepwise mixing procedure.
