Tso lus
1.4845 stainless hlau, feem ntau hu ua 310S los yog UNS S31008, yog siab - alloy austenitic stainless hlau nrog tshwj xeeb siab - kub oxidation kuj thiab creep zog. Nrog nws cov ntsiab lus siab chromium thiab npib tsib xee, nws yog tsim los rau kev pabcuam txuas ntxiv ntawm qhov kub txog li 1150 degree, ua rau nws yog cov khoom siv tseem ceeb rau cov khoom siv hauv cub tawg, cov khoom siv kho cua sov, thiab siab -kub cov txheej txheem kev lag luam uas tsis kam mus scaling thiab oxidation tseem ceeb heev.
Qhov siab - kub resistant qib no yog tus qauv raws li cov npe tseem ceeb thoob ntiaj teb.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4845 / 310S
Exceptional High -Tub kub Oxidation Resistance:Tsim ib qho chaw ruaj khov, ua raws chromium oxide txheej uas tiv thaiv kev ntsuas thiab oxidation hauv kev pabcuam txuas mus txog 1150℃thiab kev pabcuam cuam tshuam txog 1050 degree.
High Creep thiab Repture Strength:Ua kom muaj kev ncaj ncees nyob rau hauv cov khoom siv thauj khoom ntawm qhov ntsuas kub zoo dua li cov qib austenitic feem ntau vim nws cov ntsiab lus siab nickel.
Zoo Sulfur Resistance:Ua tau zoo nyob rau hauv cov huab cua uas muaj cov tshuaj sulfur, uas tuaj yeem degrade ntau lwm yam stainless hlau.
Zoo heev Thermal Fatigue Resistance:Withstands rov ua cua sov thiab cua txias yam tsis muaj kev puas tsuaj loj, ua rau nws zoo tagnrho rau kev siv thermal cycling.
Cov ntawv thov tseem ceeb:
Thaum tshav kub kub kho Furnaces:Radiant tubes, muffles, retorts, baskets, thiab furnace rolls.
Tshuaj thiab Petrochemical:Reformers, pyrolysis raj, thiab catalyst txhawb cov phiaj hauv siab -cov txheej txheem kub.
Kev tsim hluav taws xob:Boiler Cheebtsam, superheaters, thiab cua sov rov qab systems.
Iav & Ceramic Manufacturing:Kub tuav khoom thiab cov rooj tog zaum.

Waste Incineration:Combustion Chambers thiab cov cua kub exchangers.
310S (1.4845) piv rau 309S (1.4833) li cas hauv siab -kev pabcuam kub?
Ob leeg yog qib siab -kub kub, tab sis 310S muaj ntau ntau chromium thiab npib tsib xee (25% Cr, 20% Ni) piv rau 309S (23% Cr, 13% Ni). Qhov no muab 310S superior oxidation tsis kam thiab muaj peev xwm kub dua - siv txuas ntxiv mus txog ~ 1150℃rau 310S piv rau ~ 1050℃rau 309S. 310S kuj muaj cov carburization zoo dua thiab sulfidation tsis kam. 309S feem ntau yog siv los ua tus nqi ntau dua -cov kev xaiv qis dua, cov kev xav tau qis dua rau cov ntawv thov qis dua rau koom nrog cov hlau tsis sib xws.
Dab tsi yog qhov txwv ntawm 310S stainless hlau?
Txawm hais tias zoo heev hauv oxidizing thiab sulfur- muaj cov huab cua, 310S muaj kev txwv tsis pub muaj kev tiv thaiv ib puag ncig thiab cov roj halogen (chlorine, fluorine). Nws cov ntsiab lus nickel siab ua rau nws kim heev dua li cov qauv qib. Nws kuj tseem tuaj yeem ua rau lub sijhawm ua sigma yog nyob rau hauv qhov kub ntawm 650-900℃rau lub sijhawm ntev, uas tuaj yeem ua rau cov khoom siv thiab txo cov tawv nqaij. Kev kho cua sov kom zoo thiab kev tswj kom txias yog qhov tseem ceeb los tswj kom muaj ductility. Rau cov xwm txheej txo qis, nickel-based alloys yuav tsim nyog dua.
