Haynes 25 (L605)<\/h3>\n

\n Alliage de cobalt-nickel-chrome-tungst\u00e8ne qui combine une excellente r\u00e9sistance \u00e0 haute temp\u00e9rature et une bonne r\u00e9sistance \u00e0 l'oxydation jusqu'\u00e0 1800\u00b0F. Il est \u00e9galement connu pour son excellente r\u00e9sistance au grippage des m\u00e9taux.\n <\/p>\n

Haynes 188<\/h3>\n

\n Alliage de cobalt-nickel-chrome-tungst\u00e8ne avec un ajout minime de lanthane. Il offre une meilleure r\u00e9sistance \u00e0 l'oxydation et une meilleure stabilit\u00e9 thermique que l'acier inoxydable. Haynes 25<\/a>, ce qui en fait la norme pour les rev\u00eatements de chambre de combustion.\n <\/p>\n

Pourquoi choisir les alliages \u00e0 base de cobalt ?<\/h3>\n

\n Les alliages \u00e0 base de nickel (comme l'Inconel) sont excellents, Alliages \u00e0 base de cobalt<\/strong> comme Haynes 25 et 188 offrent une r\u00e9sistance sup\u00e9rieure \u00e0 la corrosion \u00e0 chaud dans les atmosph\u00e8res contenant du soufre (sulfuration) et des sels fondus.\n <\/p>\n

\n Ils conservent \u00e9galement une plus grande solidit\u00e9 \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es et sont nettement plus r\u00e9sistants \u00e0 l'usure et au grippage, ce qui les rend essentiels pour les pi\u00e8ces de turbines \u00e0 gaz qui glissent ou tournent les unes contre les autres.\n <\/p>\n <\/div>\n\n

Why Choose Cobalt-Based Alloys?<\\\/h3>\\n

\\n While Nickel-based alloys (like Inconel) are excellent, Cobalt-based alloys<\\\/strong> like Haynes 25 and 188 offer superior hot corrosion resistance in atmospheres containing sulfur (sulfidation) and molten salts.\\n <\\\/p>\\n

\\n They also maintain higher strength at elevated temperatures and are significantly more resistant to wear and galling, making them critical for gas turbine parts that slide or rotate against each other.\\n <\\\/p>\\n <\\\/div>\\n\\n
