C276 yeeb nkab yog dab tsi?
Alloy C-276 yog nickel-chromium-molybdenum solid-solution ntxiv dag zog rau superalloy nrog cov tshuaj nominal ntawm 57% npib tsib xee, 16% chromium, thiab 16% molybdenum, nrog ntxiv hlau, tungsten, thiab cobalt. Nws feem ntau paub los ntawm lub npe lag luam Hastelloy® C-276 thiab lub npe UNS N10276. C-276 feem ntau yog siv nyob rau hauv ib puag ncig corrosive heev uas lwm cov hlau tsis tuaj yeem tiv taus.
Corrosion kuj
Alloy C-276 yog ib qho ntawm cov hlau uas muaj corrosion-resistant tshaj plaws. Cov npib tsib xee, chromium thiab molybdenum hauv Alloy C-276 nthuav tawm qhov muaj zog triple hem rau yuav luag txhua hom kev xeb. C-276 muaj kev tiv thaiv zoo heev los txo thiab oxidizing acids, suav nrog sulfuric acid, hydrochloric acid, thiab acetic acid. Nws kuj ua tau zoo hauv dej hiav txwv, chloride, chlorine ntub dej, oxidizing ntsev thiab hypochlorite. Cov ntsiab lus molybdenum thiab tungsten tiv thaiv ntau hom kev xeb hauv zos, nrog rau pitting, crevice corrosion thiab chloride stress corrosion cracking. C-276 muaj oxidation zoo heev ntawm qhov kub siab txog 1900 degree F (1038 degree ). C-276 tsis pom zoo rau siv nyob rau hauv huab cua oxidizing ib puag ncig xws li cov uas nthuav tawm los ntawm concentrated kub nitric acid.
Kub kub kuj
C-276 tiv thaiv oxidation ntawm qhov kub txog li 1900 degree F (1038 degree ).
Mechanical cwj pwm
Mechanical cwj pwm
Nyob rau hauv cov xwm txheej annealed, C-276 muaj lub zog tawm los ntawm 41 ksi (345 MPa). Txawm li cas los xij, muaj zog dua tuaj yeem tau txais los ntawm Pilger txheej txheem. C-276 tuav zoo heev toughness ntawm qis kub.
Thaum tshav kub kub kev kho mob cim
Kev kho cua sov
C-276 tsis tuaj yeem muaj zog los ntawm kev kho cua sov. C-276 feem ntau yog cov tshuaj annealed ntawm 2050 degree F (1121 degree) thiab ces txias sai heev.
Kev ua tau zoo
Ua haujlwm tau
C-276 tuaj yeem ua haujlwm thermal los ntawm 1600 degree F - 2250 degree F (870 degree - 1230 degree ). Nws raug nquahu kom anneal tom qab ua haujlwm kub. Cold forming yog ua tau, tab sis nws cov hauj lwm hardening tus nqi yog siab, yog li intermediate annealing yuav tsum tau.
Cov chaw thov
C-276 yog ib qho chaw ua haujlwm hauv kev lag luam tshuaj lom neeg thiab siv dav hauv kev lag luam roj thiab roj vim nws cov corrosion kuj nyob rau hauv ntau yam corrosive tshuaj. Hauv cov roj av thiab roj av, C-276 yog siv los ua tubing, casing los yog hauv ob sab phlu nyob rau hauv corrosive qaub kev pab cuam ib puag ncig nrog siab concentrations H2S, CO2 thiab chlorides. Nws kuj tseem siv rau hauv lwm qhov kev lag luam uas muaj qhov hnyav hnyav, suav nrog kev lag luam tshuaj thiab ntawv. C-276 yog siv nyob rau hauv li qub nyob rau hauv daim ntawv thov cryogenic thiab tau siv nyob rau hauv superconductors ntawm qhov kub thiab txias li tsawg li -455 degree F (-271 degree ).
CRA muaj tshwj xeeb alloy C-276 seamless tubing rau ntau yam kev lag luam thiab kev siv, suav nrog:
Cov roj thiab cov roj corrosive hnyav uas muaj CO2, H2S, SO (cov ntsiab lus sulfur) thiab chlorides
