Nimonic 263 / Haynes 263



Nimonic 263 / Haynes 263

La lega Nimonic 263 / Haynes 263 è una lega di nichel-cobalto-cromo-molibdeno progettata specificamente per combinare ottime proprietà di resistenza con eccellenti caratteristiche anche dopo trattamento temico.
Sebbene la sua resistenza a temperature elevate non sia tanto elevata quanto i materiali come il Waspaloy o la lega R-41, la lega 263 è molto più facile da sinterizzare e saldare.
La lega 263 presenta un'eccellente duttilità a trazione nelle temperature intermedie e normalmente non è soggetta ad alcuna sollecitazione Applicazioni tipiche:
Componenti per turbine a gas
Attrezzature per il trattamento termico
Applicazioni ad alta temperatura / alta resistenza
