Taw qhia
Super alloys los yog kev ua haujlwm siab alloys muaj nyob rau hauv ntau yam duab thiab muaj cov ntsiab lus sib txawv ua ke kom tau txais cov txiaj ntsig tshwj xeeb.Cov alloys no yog peb hom uas suav nrog hlau-raws li, cobalt-based thiab nickel-based alloys.Cov nickel-based thiab cobalt-based super alloys muaj xws li cam khwb cia lossis wrought raws li alloys raws li muaj pes tsawg leeg thiab daim ntawv thov.
Super alloys muaj oxidation zoo thiab creep tsis kam thiab tuaj yeem ntxiv dag zog los ntawm nag lossis daus hardening, solid-solution hardening thiab ua hauj lwm hardening txoj kev.Lawv kuj tuaj yeem ua haujlwm nyob rau hauv siab mechanical stress thiab high temperatures thiab kuj nyob rau hauv qhov chaw uas yuav tsum tau muaj kev ruaj ntseg nto.
HASTELLOY (r) C276 yog ib qho kev tiv thaiv corrosion-resistant alloy uas tiv thaiv txoj kev loj hlob ntawm grain ciam precipitates uas degrade corrosion kuj.
Cov ntaub ntawv hauv qab no muab cov ntsiab lus ntawm HASTELLOY(r) C276.
