Disclosed herein is a method for pretreatment of a metallic substrate for a subsequent metal cold forming process, said method including (1) providing at least one substrate, (2) contacting the at least one surface of the substrate provided in step (1) with an aqueous lubricant composition (A). and optionally (3) drying the coating film obtained after having performed step (2). Further disclosed herein are a pretreated metallic substrate obtainable by the aforementioned method, a method of cold forming of a metallic substrate including a step of subjecting the inventive pretreated metallic substrate to a cold forming process, an aqueous lubricant composition (A) as defined above, and a master batch for preparing the aqueous composition (A).

A composition for inhibiting corrosion and/or removing hydrocarbonaceous deposits in oil and gas applications is provided. The composition comprises an iron sulfide dissolver, an organic solvent, and a corrosion inhibitor.

An aqueous composition for reducing corrosive removal of material in pickling of metallic surfaces comprising bare and/or galvanized steel. The composition includes a mixture of a compound of the formula R.sup.1O—(CH.sub.2).sub.x—C≡C—(CH.sub.2).sub.y—OR.sup.2 in which R.sup.1 and R.sup.2 are both H, and a compound of the formula R.sup.1O—(CH.sub.2).sub.x—C≡C—(CH.sub.2).sub.y—OR.sup.2 in which R.sup.1 and R.sup.2 are each, independently of one another, an HO—(CH.sub.2).sub.w— group with w≥2. X and y are each, independently of one another, from 1 to 4 in each of the two compounds of the formula R.sup.1O—(CH.sub.2).sub.x—C≡C—(CH.sub.2).sub.y—OR.sup.2. A process for pickling a metallic surface with reduced corrosive removal of material is disclosed.

Methods, compositions, and kit(s) for removing corrosion or scale from a metal or a non-metal article are disclosed. In a first stage of the method, an article exhibiting corrosion can be exposed to an acid wash composition including a first acid component having one or more of HCl, Phosphoric Acid, Oxalic Acid, a second acid inhibitor/surfactant component including ethoxylated alkyl mercaptan, and a third thixotropic gelling agent component including Talc or Fumed silica, sufficient to cause gelling of the acid wash composition. In a second stage of the method performed subsequent to the first stage, the article can be exposed to an acid neutralizing composition comprising bicarbonate, borax, isopropyl alcohol and water.
