La barre Inconel 718 est un alliage nickel-chrome haute r\u00e9sistance et r\u00e9sistant \u00e0 la corrosion, con\u00e7u pour une utilisation en environnements extr\u00eames. Compos\u00e9 principalement de nickel (50-55%) et de chrome (17-21%), l'Inconel 718 offre des propri\u00e9t\u00e9s m\u00e9caniques exceptionnelles \u00e0 haute temp\u00e9rature et une grande r\u00e9sistance \u00e0 l'oxydation et \u00e0 la corrosion.<\/p>\n

Il conserve sa r\u00e9sistance jusqu'\u00e0 700 \u00b0C (1\u00a0292 \u00b0F), ce qui le rend id\u00e9al pour les industries a\u00e9ronautique, de production d'\u00e9nergie et de transformation chimique. Cet alliage pr\u00e9sente \u00e9galement une excellente soudabilit\u00e9 et est souvent utilis\u00e9 dans la production d'aubes de turbines, de turbines \u00e0 gaz et de composants structurels de moteurs \u00e0 r\u00e9action. \u00c9galement connu sous le nom UNS N07718, l'Inconel 718 est largement reconnu pour sa capacit\u00e9 \u00e0 r\u00e9sister aux conditions difficiles sans compromettre ses performances.<\/p>\n
