Incoloy 825 Khoom Khoom
Alloy 825, tseem hu uaIncoloy 825 UNS 08825, yog nickel-hlau-chromium alloy nrog cov ntsiab lus ntxiv xws li molybdenum, tooj liab, thiab titanium. Nws muaj kev tiv thaiv zoo rau kev xeb hauv ntau qhov chaw, suav nrog sulfuric acid, phosphoric acid, thiab dej hiav txwv. Cov hlau no feem ntau xaiv rau cov cuab yeej siv hauv kev lag luam desalination, vim nws tuaj yeem tiv taus qhov siab salinity qib ntawm seawater tsis tawg.
Hastelloy C276 Khoom Khoom
Ntawm qhov tod tes,Hastelloy C276yog cov nickel-molybdenum-chromium alloy uas muaj kev tiv thaiv zoo rau ntau qhov chaw corrosive, nrog rau cov kua qaub muaj zog, chlorides, thiab oxidizing cov neeg ua haujlwm. Nws feem ntau yog siv rau hauv kev lag luam chemical uas muaj cov tshuaj hnyav, xws li hauv kev tsim cov sulfuric acid thiab hydrochloric acid. Alloy C276 UNS N10276 kuj tseem siv rau hauv cov ntawv thov uas muaj qhov kub thiab txias siab, xws li hauv cov khoom siv hluav taws xob los yog cov hlab ntsha reactor.
Kev ntxhov siab Corrosion Cracking (SCC)
Ib qho ntawm qhov sib txawv ntawm ob lub alloys no yog lawv qhov tsis kam rau chloride-induced stress corrosion cracking (SCC). Thaum Incoloy 825 muaj kev tiv thaiv zoo rau SCC hauv ntau qhov chaw, nws yuav tsis yog qhov kev xaiv zoo tshaj plaws thaum ua haujlwm nrog cov tshuaj chlorides siab. Hauv kev sib piv, Hastelloy C276 yog cov tshuaj tiv thaiv chloride-induced SCC, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau kev siv cov tshuaj chlorides.
Thermal stability
Lwm qhov sib txawv tseem ceeb ntawm cov hlau no yog lawv cov thermal stability. Alloy 825 muaj qhov ua haujlwm siab tshaj plaws ntawm 550 degree (1020 degree F), thaum alloy c276 tuaj yeem tiv taus kub txog 1,050 degree (1,922 degree F). Qhov no ua rau cov hlau tom kawg yog qhov kev xaiv zoo dua rau cov ntawv thov uas muaj qhov kub thiab txias.
