Thaum xaiv npib tsib xee-raws li alloys rau huab cua corrosion, siab kub, los yog siab - ib puag ncig kev ntxhov siab, Inconel 718 thiab Hastelloy C276 feem ntau piv. Txawm hais tias ob qho tib si yog cov hwm superalloys, lawv cov tshuaj muaj pes tsawg leeg qhia txog cov qauv tsim qauv sib txawv, uas cuam tshuam ncaj qha rau kev tiv thaiv corrosion, txhua yam muaj zog, kev pabcuam kub, thiab tus nqi.
Inconel 718 yog dab tsi?
Inconel 718 (UNS N07718) yog lub siab -lub zog, npib tsib xee-chromium superalloy paub rau tshwj xeeb tiv thaiv corrosion thiab kub kub (txog 1300℃F / 704 degree), tuav lub zog ntawm huab cua kub, thiab weldability zoo heev. Nws muaj hnub nyoog-hardenable, txhais tau tias nws muaj zog dua nrog kev kho cua sov, ua rau nws zoo tagnrho rau kev thov aerospace ( dav hlau cav, foob pob ua ntxaij), roj & roj (cov cuab yeej downhole), thiab cov khoom lag luam uas xav tau kev ua haujlwm siab hauv corrosive lossis siab - cua sov ib puag ncig.
Hastelloy C276 yog dab tsi?
Hastelloy C-276 (UNS N10276) yog ntau yam npib tsib xee-chromium-molybdenum superalloy paub rau tshwj xeeb corrosion kuj nyob rau hauv ib puag ncig tshuaj lom neeg hnyav, tshwj xeeb tshaj yog tiv thaiv pitting, crevice corrosion, thiab kev ntxhov siab-corrosion tawg hauv chlorides, ua tsaug rau nws cov ntsiab lus qis thiab cov pa roj carbon ntau. molybdenum / chromium / tungsten qib, ua rau nws zoo tagnrho rau kev ua tshuaj, roj & roj, thiab marine industries nyob rau hauv daim ntawv thov xws li reactors, tshav kub exchangers, thiab scrubbers.
