Hastelloy X


Hastelloy X
Hastelloy X è una lega di Nichel-Cromo-Ferro-Molibdeno con una combinazione eccezionale di resistenza alla corrosione, facilità di lavorazione e resistenza alle alte temperature. È eccezionalmente resistente alle incrinature dovute alla tensocorrosione nelle applicazioni in ambito petrolchimico.La lega mostra anche una buona duttilità dopo un prolungato esposizione a temperature di 1200, 1400, 1600 ° F (650, 760 e 870 ° C).

Hastelloy X viene ampiamente utilizzato nei motori a turbina a gas per componenti di zone di combustione come condotti di transizione, barattoli per combustori, barre spray e portafiamma, nonché nei postcombustori, tubi di scappamento e riscaldatori di cabina. È raccomandato per l'uso in applicazioni di forni industriali perché ha una resistenza insolita alle atmosfere ossidanti, riducenti e neutre.
