1.\u00a0<\/strong>Introduction aux mat\u00e9riaux 2520Si2<\/strong><\/p>\n

L'acier inoxydable 2520Si2 est un acier inoxydable aust\u00e9nitique au chrome et au nickel qui pr\u00e9sente une bonne r\u00e9sistance \u00e0 l'oxydation et \u00e0 la corrosion, car le pourcentage plus \u00e9lev\u00e9 de chrome et de nickel lui conf\u00e8re une bien meilleure r\u00e9sistance au fluage et lui permet de continuer \u00e0 fonctionner \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es. Il s'agit d'un nouveau mat\u00e9riau am\u00e9lior\u00e9 sur la base du 310S.<\/p>\n
