1. Qhov kub siab tshaj plaws rau kev txhim kho alloloy alloys
Qhov "kub tshaj plaws" rau incoloy alloys tsis yog tus nqi universal {}}}} nws txawv ntawmAlloy Qib, raws li txhua qhov kev nkag siab txawv yog engineered rau cov kub kub (los ntawm cua sov kom high - kub kev pab). Qhov tseem ceeb txhais tau hais tias kub siab tshaj plaws yog lub peev xwm lub peev xwm los khaws ciaoxidation tsis kam, NEEG KHO TSHUAB Muaj Zog (Tshwj Xeeb Tshaj Plaws Creamp Kuj), thiabmicrostration kev ruaj khovtsis muaj kev cuam tshuam ntau dhau los yog xeb. Hauv qab no yog qhov kev pab cuam siab tshaj plaws rau cov qib kev cuam tshuam ntau, nrog rau lawv qhov chaw:
| Incoloy qib | Qhov Kev Pab Cuam Tshuam Kub | Qhov tseem ceeb tshajToos |
|---|---|---|
| Incoloy 800 | ~ 870℃(1,600℃f) | Balanced Nickel -}}}} chromium muaj pes tsawg leeg (30}}}}}}}}} Tsim los rau nruab rau cov qib siab oxidation tiv thaiv (piv txwv li, kev hloov pauv kub) tab sis txwv tsis muaj zog saum 870 degree. |
| Incoloy 800h | ~ 980 Qib (1,800 Qib F) | Hloov kho los ntawm Incoloy 800 nrog ntau dua cov pa roj carbon monoxide (0.06-0.10%) thiab tswj cov qoob loo loj. Cov pa roj carbon ntau dua cov pa roj carbon ntau dua, tso cai rau kev siv kub ntawm 100-110℃siab dua incoloy 800 (piv txwv li, cua sov rauv yaj). |
| Incoloy 800ht | ~ 1,100℃(2,010℃f) | Txuas ntxiv rau Ultra - qhov kub siab dua nrog ntau dua aluminium + titanium (1.0% tag nrho) thiab stricter grain. Ib qho ntxiv no siv zog txhawb nqa dej nag (piv txwv li, aln), enterping creep tsis zoo nyob rau hauv huab cua sov (piv txwv, petrochemical reformer tub). |
| Incoloy 825 | ~ 815℃(1,500℃f) | Ua ntej corrosion tsis kam (vs. siab - kub lub zog) nrog Molybdenum (2.5-3.5-3.0%). Nws cov txheej txheem kev tiv thaiv tau muab kev tiv thaiv kom txaus txog 815 qib, tab sis saum toj no, corrosion tsis kam (siv cov tshuaj lom neeg, tsis yog cua sov). |
| Incoloy 925 | ~ 650℃(1,200℃f) | Kev mob corrosion - tsis kam, nag lossis daus -} Lub zog ntawm titanium thiab txhuas). Nws qhov kub tshaj plaws yog txwv los ntawm kev ruaj ntseg ntawm nws cov peev xwm ntxiv dag zog {}} qhov ncauj lus sib xws (siv hauv cov roj / roj downhole cov cuab yeej). |
Tseem Ceeb: "Ntau tshaj plaws" feem ntau yog hais txogKev Pabcuam Nruam(ntev {-}} Term kis, piv txwv li, 10, 000+ teev). Txog thaum luv -}, muaj kev sib txawv, qee qhov kev phom sij 800ht txog 1,100 degree.
2. Dab tsi yog qhov sib npaug ntawm incoloy 800h?
Incoloy 800h yog lub siab - kub nickel {}} chromium alloy txhais los ntawm cov qauv zoo liASTM B409(ntawv / phaj) thiabASTM B408(bar), nrog cov ntsiab lus tseem ceeb: 30-35% ni, 19-23% cr, 0.0-0.10% c, thiab tswj cov qoob loo loj (los txhim kho cov neeg quav). Nws cov "sib npaug" yog cov alloys los ntawm lwm cov qauv (thoob ntiaj teb lossis txoj hauv kev) uas phim nwsTshuaj Muaj Tshuaj, Cov Khoom Siv Neeg Kho Tshuab, thiabsiab - kub kev ua tau zooRau kev hloov pauv tau nyob rau hauv cov ntawv thov uas zoo li rauv leeg, kev sib pauv cua sov, lossis hloov pauv hluav taws xob.
