Hastelloy X yog ib hom nickel puag superalloy nrog cov ntsiab lus hlau siab, uas feem ntau yog ntxiv dag zog los ntawm cov khoom siv ntawm chromium thiab molybdenum.Nws muaj kev tiv thaiv zoo thiab kev ua haujlwm corrosion, nruab nrab endurance thiab creep zog hauv qab 900 ℃, zoo txias thiab kub ua formability thiab vuam kev ua tau zoo.
Siv nyob rau hauv kev tsim cov aero-engine combustion chamber qhov chaw thiab lwm yam kub qhov chaw, nyob rau hauv 900 ℃ rau ib ntev lub sij hawm, luv luv ua hauj lwm kub txog li 1080 ℃.

1. Zoo heev oxidation tsis kam ntawm qhov kub siab (> 1200 ℃)).
2. Zoo siab kub lub zog.
3. Zoo formability thiab weldability.
4. Zoo tiv thaiv kev ntxhov siab corrosion cracking.
Vim hais tias ntawm nws cov corrosion kuj nyob rau hauv ntau yam cua kub thiab zoo heev kub lub zog, HastelLoyx tau lug siv nyob rau hauv ntau yam kub kub.
