1. Muaj pes tsawg leeg
Cov ntsiab lus npib tsib xee (ib txwm 40-60%, sib txawv ntawm qib) raws li cov hlau sib txuas.
Tseem Ceeb Molybdenum (10-25%) kom tiv thaiv pitting, thiab tawm tsam los ntawm kev txo cov kua qaub (piv txwv li hydrochloric, sulfuric).
Chromium (10-20%) rau oxidation tiv taus thiab ruaj khov hauv oxidizing ib puag ncig.
Ntxiv ntawm tungsten, hlau, lossis cobalt hauv qee qib (piv txwv li, hastelloy c276 muaj ~ 4% tungsten kom txhim kho rau corrosion).
Qeb Nickel Cov ntsiab lus (20-50%, nyob ntawm cov qib) sib npaug nrog hlau (feem ntau ntau tshaj plaws ntau tshaj, 30-60%).
Chromium (15-30%) rau oxidation tiv taus ntawm qhov kub.
Ntxiv ntawm txhuas thiab titanium nyob rau hauv qee qib (piv txwv li, incoloy 800h) los tsim intermetallic tebchaw (gamma prime theem) uas ntxiv dag zog rau kev kub siab.
Molybdenum yog tam sim no nyob rau hauv qee qib (piv txwv li, incoloy 825) tab sis ntawm qis dua qib siab tsis kam nyob rau hauv ib puag ncig tshwj xeeb (xws li sulfuric acid).
2. Cov yam ntxwv tseem ceeb
3. Kev thov
Kev Ua Haujlwm Siv Tshuaj (Reactors, kav dej, li qub cov kua qaub li sulfuric, hydrochloric, lossis phosphoric acid).
Cov cuab yeej tswj cov pa paug dej tsis huv (cov roj, nrog cov tshuab desulfurization).
Roj thiab roj kev lag luam (Cheebtsam hauv cov roj qaub nyob ib puag ncig muaj cov high thiab chloride qib).
Kws tsim khoom lag luam (khoom uas yuav tsum muaj ultra-ntshiab, corrosion-dawb thaj chaw).
Cov tshuab hluav taws xob tshav kub, ua kom sov rau hauv cov fais fab ntoo thiab petrochemical cov chaw (piv txwv li, incoloy 800h).
Aerospace thiab lub Cheebtsam tsheb (cov khoom siv yog li ib qho, cov tshuab tso pa tawm) raug rau qhov kub siab.
Marine engineering (kav dej thiab li qub nyob rau hauv seawater, txawm tias tsawg tsis tiv taus hastelloy rau chloride-ntxias pitting).
Cov khoom noj khoom noj khoom haus (vim yog cov oxidation zoo tsis kam thiab muaj peev xwm).
4. Cov qhab nia
C276: Feem ntau siv tau siv; txawj ntse nyob rau hauv ib puag ncig acid thiab chloride daws.
C22: Txhim kho tsis kam rau oxidizing cov neeg sawv cev piv rau C276.
B2: Zoo rau kev tiv thaiv kom tsis kam rau txo cov kua qaub (xws li hydrochloric acid).
800 / 800H: High-High-Kub Zog; siv nyob rau hauv rauv tub.
825: cov nyiaj nyiag los tiv thaiv (sulfuric acid, seaterater) thiab kev ua haujlwm kub nruab nrab.
926: Txhim Kho Molybdenum cov ntsiab lus rau kev ua kom zoo dua chloride pitting kuj, siv nyob rau hauv ntug dej thiab roj.
