Mawu Oyamba
Ma super alloys kapena ma alloys apamwamba kwambiri amapezeka m'mawonekedwe osiyanasiyana ndipo amakhala ndi zinthu zophatikizika zosiyanasiyana kuti mupeze zotsatira zenizeni.Ma alloyswa ndi amitundu itatu omwe amaphatikizapo chitsulo, cobalt-based and nickel-based alloys.Ma alloys opangidwa ndi nickel komanso cobalt amapezeka ngati ma aloyi opangidwa kapena opangidwa molingana ndi kapangidwe kake ndi kagwiritsidwe ntchito.
Super Alloy HASTELLOY(r) C276 (UNS N10276)
Ma super alloys ali ndi okosijeni wabwino komanso kukana kukwawa ndipo amatha kulimbikitsidwa ndi kuuma kwa mvula, kuuma kolimba komanso njira zowumitsa ntchito.Atha kugwiranso ntchito pansi pa kupsinjika kwa makina komanso kutentha kwambiri komanso m'malo omwe amafunikira kukhazikika kwapamwamba.
HASTELLOY(r) C276 ndi alloy yolimbana ndi dzimbiri yomwe imakana kukula kwa malire a tirigu omwe amachepetsa kukana kwa dzimbiri.
Tsamba lotsatirali likuwonetsa mwachidule HASTELLOY(r) C276.
