Abstract:
Steel substrate suitable for forming operations which comprises a coating thereon wherein the coating comprises a corrosion resistant layer of polyamide-imide having a dry film thickness between 1 and 10 μm and wherein the layer of polyamide-imide further comprises a hydroxyamine.
Abstract:
Method for manufacturing a steel product which comprises the steps of: (i) providing a steel substrate; (ii) providing a solution comprising a slag material; (iii) contacting the steel substrate with the solution comprising the slag material to form a corrosion protective layer on the surface of the steel substrate, wherein the corrosion protective layer consists mainly of a compound formed from oxides comprised in the slag material.
Abstract:
The present invention relates to a steel or coated steel substrate comprising a corrosion protective coating on the surface thereof, wherein the corrosion protective coating comprises a water soluble synthetic polymer and a carbohydrate.
Abstract:
The invention relates to a hot-formable steel for use in hot forming comprising a hot- formable steel strip, sheet or blank, a metal or metal alloy coating formed on the hot- formable steel strip, sheet or blank and a metallurgical slag based coating formed on the metal or metal alloy coating, wherein the metal or metal alloy coating comprises zinc and/or aluminium and the metallurgical slag based coating comprises a metallurgical slag and a polymeric material.
