Coated steel substrate

Abstract

A coated stainless-steel substrate including a coating including nanographites and a binder being sodium silicate, wherein the stainless-steel substrate has the following composition in weight percent: C≤1.2%, Cr≥11.0%, Ni≥8.0% and on a purely optional basis, one or more elements such as Nb≤6.0%, B≤1.0%, Ti≤3.0%, Cu≤5.0%, Co≤3.0%, N≤1.0%, V≤3.0%, Si≤4.0%, Mn≤5.0%, P≤0.5%, S≤0.5%, Mo≤6.0%, Ce≤1.0%, the remainder of the composition being made of iron and inevitable impurities resulting from the elaboration. A method for the manufacture of this coated stainless-steel substrate is also provided.
