Lega di Stellite 12

La Stellite 12 può essere considerata una lega intermedia tra la Stellite 6 e la Stellite 1. Contiene una frazione maggiore di carburo duro disperso in una matrice di CoCr. Contiene una frazione maggiore di carburi duri e fragili rispetto alla Stellite 6 e presenta una maggiore resistenza all’erosione a basso angolo, all’abrasione e all’usura da scorrimento, pur mantenendo una ragionevole resistenza all’impatto e alla cavitazione. La Stellite 12 è spesso utilizzata in auto-accoppiamento o in scorrimento contro la Stellite 6 o la Stellite 1.

Il maggior contenuto di tungsteno offre migliori proprietà ad alta temperatura rispetto alla Stellite 6 e può essere utilizzata a temperature fino a circa 700 ̊C.
