Abstract (en)

High chromium and silicon content steel powder, for thermal coating of metal parts exposed to chlorine, chloride and/or sulfate corrosion. A powder of an alloy steel of composition (by wt.) more than 20 to 50% Cr, more than 3 to 10% Si, balance Fe and impurities is used for thermal coating of metal parts which are exposed, during use, to corrosive attack by chlorine-, chloride- and/or sulfate-containing media.

Abstract (de)

Die Erfindung betrifft Beschichtungen aus ferritischen Stahllegierungen auf Metall-Bauteilen, vornehmlich niedriglegiertem Stahl, vorzugsweise Rohren und Rohrwänden, zum Zwecke des Korrosionsschutzes gegen heiße chlor- und/oder chlorid- und/oder sulfathaltige Medien z.B. für Anlagenbauteile für die thermische Müllentsorgung oder Kupferraffinierung. <IMAGE>
