FAQ

Q: Dab tsi yog qhov siab tshaj plaws ua haujlwm kub ntawm SUS310S?A: SUS310S tuaj yeem ua haujlwm tsis tu ncua ntawm qhov kub txog li 1150℃hauv oxidizing cua, ua rau nws yog ib qho ntawm cov cua sov tshaj plaws -cov qib austenitic stainless hlau resistant muaj. Qhov tshwj xeeb siab - qhov kub thiab txias kev ua haujlwm no yog vim nws cov ntsiab lus chromium thiab npib tsib xee, uas ua rau cov qauv austenitic ruaj khov thiab ua kom muaj qhov ntom ntom, tiv thaiv chromium oxide zaj duab xis rau saum npoo. Ntawm qhov kub siab tshaj 1150 degree, oxide txheej yuav pib tawg, ua rau kom ceev oxidation thiab scaling, tab sis cov hlau tseem tuaj yeem tiv taus luv luv -lub sij hawm raug kub siab dua thaum muaj xwm txheej ceev. Hauv kev txo cov huab cua, qhov siab tshaj plaws kev khiav hauj lwm kub yog me ntsis qis, nyob ib ncig ntawm 1040 degree, tiv thaiv carbide nag lossis daus thiab embrittlement. Cov hlau muaj peev xwm tswj tau nws cov khoom siv kho tshuab thiab kev tiv thaiv corrosion ntawm qhov kub thiab txias ua rau nws zoo tagnrho rau cov ntawv thov tseem ceeb xws li lub tshuab hluav taws xob thiab cov raj radiant, qhov twg lwm cov qib yuav sai sai degrade.

Q: SUS310S ua haujlwm li cas hauv carburizing cua?A: SUS310S muaj kev tiv thaiv zoo heev rau carburizing cua, uas muaj ntau hauv cov txheej txheem kho cua sov xws li carburizing thiab carbonitriding. Nyob rau hauv cov cheeb tsam no, carbon atoms diffuse mus rau hauv cov hlau nto, tab sis cov ntsiab lus siab chromium ntawm SUS310S tsim ib tug ruaj khov chromium carbide txheej uas tiv thaiv cov pa roj carbon ntau dhau thiab tswj cov hlau cov qauv kev ncaj ncees. Tsis zoo li cov qib qis dua -chromium xws li SUS304, uas tuaj yeem ua nkig lossis poob lawv cov corrosion kuj nyob rau hauv carburizing cua, SUS310S khaws nws cov tawv thiab ductility, kom ntseeg tau ntev -lub sij hawm durability. Qhov qis- cov ntsiab lus carbon ntawm SUS310S kuj txo qhov kev pheej hmoo ntawm kev tsim carbide sab hauv, uas tuaj yeem cuam tshuam cov hlau cov khoom siv kho tshuab. Qhov kev tiv thaiv rau carburization no ua rau SUS310S yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv hluav taws xob uas raug rau qhov kub thiab txias thiab carbon- nplua nuj gases, xws li retorts thiab cua sov cov ntsiab lus.

Q: Txoj kev vuam zoo li cas rau SUS310S?A: SUS310S tuaj yeem welded siv tag nrho cov txheej txheem fusion vuam, suav nrog TIG, MIG, SMAW, thiab submerged arc vuam. Nws cov ntsiab lus nickel siab ua kom lub pas dej zoo sib xws thiab txo qhov kev pheej hmoo ntawm kub tawg, ib qho teeb meem tshwm sim hauv siab -chromium steels. Thaum vuam SUS310S, nws raug nquahu kom siv cov hlau muab tub lim nrog cov ntsiab lus zoo sib xws lossis siab dua chromium thiab npib tsib xee kom tswj cov hlau siab - qhov kub thiab txias ua haujlwm thiab corrosion kuj. Piv txwv li, siv 310 los yog 310L muab tub lim hlau ua kom ntseeg tau tias cov vuam sib txuas muaj tib yam oxidation kuj zoo li lub hauv paus hlau, tiv thaiv tsis ua hauj lwm ntxov hauv siab - daim ntawv thov kub. Qhov qis-carbon cov ntsiab lus ntawm SUS310S kuj txhais tau hais tias lub tshav kub- cuam tshuam cheeb tsam (HAZ) muaj kev cuam tshuam zoo intergranular corrosion, tshem tawm qhov xav tau tom qab-weld heat treatment feem ntau. Txawm li cas los xij, rau cov ntu tuab lossis cov ntawv thov uas cuam tshuam rau qhov chaw corrosive, ib qho kev tshaj tawm -weld anneal yuav raug pom zoo los txhim kho qhov corrosion kuj ntawm HAZ.

Q: SUS310S piv rau npib tsib xee-raws li alloys nyob rau hauv siab -kub siv?A: SUS310S muaj tus nqi-txoj kev zoo rau npib tsib xee-raws li cov alloys xws li Inconel thiab Hastelloy nyob rau hauv ntau qhov siab - kub daim ntawv thov, thaum muab piv rau oxidation kuj mus txog 1150℃. Nickel-raws li alloys muaj ntau dua nickel cov ntsiab lus thiab feem ntau muaj xws li ntxiv alloying ntsiab xws li molybdenum thiab tungsten, uas muab lawv superior tsis kam mus corrosion nyob rau hauv ib tug nruj heev tshuaj lom neeg ib puag ncig thiab siab creep zog ntawm huab cua kub. Txawm li cas los xij, cov alloys no tseem kim dua SUS310S, ua rau lawv tsis tshua muaj txiaj ntsig rau tus nqi - cov ntawv thov nkag siab. SUS310S yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas oxidation tsis kam yog qhov tseem ceeb, xws li cov khoom siv hluav taws xob thiab cov raj hluav taws xob, thaum cov nickel-raws li alloys zoo dua rau cov ntawv thov uas muaj cov tshuaj corrosive lossis kub siab tshaj 1150 degree. Nyob rau hauv cov nqe lus ntawm weldability thiab formability, SUS310S yog yooj yim rau fabricate tshaj feem ntau cov nickel{16}}raws li alloys, txo cov nqi tsim khoom thiab sij hawm txhuas.

Q: SUS310S puas tuaj yeem siv rau hauv qhov chaw acidic?A: SUS310S muaj nruab nrab tsis kam mus rau dilute acids xws li sulfuric acid thiab hydrochloric acid nyob rau hauv chav tsev kub, tab sis nws tsis pom zoo rau siv nyob rau hauv concentrated acidic ib puag ncig los yog nyob rau hauv siab kub. Nws cov ntsiab lus chromium siab muab qee qhov kev tiv thaiv acid nres, tab sis nws tsis muaj cov ntsiab lus molybdenum pom hauv qib zoo li SUS316, uas yog qhov tseem ceeb rau kev tiv thaiv pitting thiab crevice corrosion hauv acidic media. Hauv cov kua qaub diluted, SUS310S tuaj yeem siv rau luv luv - daim ntawv thov, tab sis ntev ntev yuav ua rau gradual corrosion thiab degradation. Rau cov acidic ib puag ncig, qib zoo li SUS316 lossis npib tsib xee-raws li alloys yog qhov tsim nyog dua, vim lawv muaj kev tiv thaiv corrosion zoo dua thiab tuaj yeem tiv taus cov kua qaub ntau dua. Txawm li cas los xij, SUS310S ua tau zoo nyob rau hauv nruab nrab thiab alkaline ib puag ncig, ua rau nws zoo tagnrho rau cov ntawv thov xws li boiler Cheebtsam thiab tshuaj reactors uas tuav tsis yog - kua qaub ntawm qhov kub thiab txias.
