Hastelloy C276 thiab alloy C-276 yog hais txog tib yam alloy nickel-based, uas yog hu ua UNS N10276. Cov alloy no paub txog nws txoj kev tiv thaiv corrosion zoo heev hauv ntau qhov chaw hnyav, suav nrog cov uas muaj oxidizing thiab reducing acids, chloride-containing media, thiab dej hiav txwv. Cov lus "Hastelloy C276" thiab "alloy C-276" yog siv sib pauv los qhia txog cov alloy tshwj xeeb no. Lub npe "Hastelloy" yog lub cim lag luam ntawm Haynes International, Inc., uas tau tsim thiab tsim cov alloy. Lo lus dav dav "alloy C-276" yog ib txoj hauv kev siv los hais txog cov alloy no raws li nws lub npe UNS. Hauv kev xaus, tsis muaj qhov sib txawv ntawm Hastelloy C276 thiab alloy C-276; lawv yog tib yam alloy thiab tsuas yog xa mus rau kev siv cov npe sib txawv.
Hastelloy C22 thiab C-276 yog ob qho tib si nickel-based superalloys nrog cov khoom sib xws.
Txawm li cas los xij, muaj qee qhov sib txawv tseem ceeb ntawm ob qho no: Kev Sib Xyaws: Hastelloy C22 muaj kwv yees li 56% nickel, 22% chromium, 13% molybdenum, 3% tungsten, thiab me me ntawm cov hlau, cobalt, thiab lwm yam ntsiab lus.
