PIASTRA E LAMIERA IN LEGA DI NICHEL 718

LAMIERA E PIASTRA IN LEGA DI NICHEL 718 - AMS 5596, AMS 5597

La lega 718 (nota anche con il nome commerciale di Special Metals Inconel 718), è una lega di nichel-cromo che può essere trattata termicamente per dare alta resistenza, buona resistenza alla corrosione ed essere facilmente fabbricata in parti complesse con una buona tenuta alla rottura post-saldatura. La lega 718 può funzionare efficacemente tra -423 e 1300 gradi F.
