Tso lus
1.4833 stainless hlau, feem ntau hu ua 309S los yog UNS S30908, yog siab -alloy austenitic stainless hlau tsim los rau oxidation zoo heev thiab siab - kub zog. Nrog nws cov ntsiab lus siab chromium thiab npib tsib xee, nws zoo - haum rau kev pabcuam txuas ntxiv ntawm qhov kub txog li 1050 degree, ua rau nws txhim khu kev qha thiab tus nqi- kev xaiv zoo rau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom siv cua sov uas 310S yuav dhau los - tau teev tseg.
Qhov siab - kub resistant qib no yog standardized nyob rau hauv loj thoob ntiaj teb systems.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4833 / 309S
Zoo heev High -Temperature Oxidation Resistance:Tsim cov txheej txheem chromium oxide ruaj khov uas tiv thaiv kev scaling thiab oxidation hauv kev pabcuam txuas ntxiv mus txog 1050 degree, nrog kev ua haujlwm zoo hauv kev pabcuam cuam tshuam txog 980 degree.
Zoo Thermal Fatigue Resistance:Ua tau zoo nyob rau hauv cyclic cua sov thiab txias tej yam kev mob vim nws ruaj khov austenitic qauv thiab zoo thermal conductivity.
Resistance rau Sulfur Atmospheres:Tuav tau zoo dua li ntau lwm cov hlau tsis muaj steel hauv ib puag ncig uas muaj cov tshuaj sulfur sib xyaw.
Tus nqi -Kev Ua Tau Zoo Siab-Tsuas Kub:Muab kev ua tau zoo heev ntawm tus nqi qis dua siab dua - qib alloyed xws li 310S, ua rau nws zoo tagnrho rau cov ntawv thov uas tsis tas yuav muaj peev xwm kub siab tshaj plaws.
Cov ntawv thov tseem ceeb:
Thaum tshav kub kub kho Furnaces:Radiant tubes, retorts, baskets, furnace linings, thiab annealing npog.
Kev ua tshuaj lom neeg:High -kub reactors, reactor tubes, thiab cov khoom siv pyrolysis.
Kev tsim hluav taws xob:Boiler Cheebtsam, superheaters, thiab cua sov rov qab units.
Vuam Filler Hlau:Dav siv los ua ib qho overlay lossis muab tub lim rau koom nrog cov hlau sib txawv, tshwj xeeb tshaj yog rau cladding carbon steel nrog stainless hlau.
Cement thiab Lime Kilns:Cyclones thiab ducting nyob rau hauv preheater systems.
Kev lag luam ceramic:Kiln rooj tog thiab tsheb saum.
309S (1.4833) piv rau 310S (1.4845) li cas hauv siab -kub siv?
Ob leeg yog qib siab - kub, tab sis 310S muaj ntau dua 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 siab tshaj qhov kev pabcuam kub kub (1150℃vs. 1050 degree). 309S feem ntau yog siv raws li tus nqi ntau dua-kev xaiv zoo rau cov mob me ntsis, rau cov ntawv thov uas qhov kub siab tshaj plaws yog qis dua 1050 degree, los yog qhov chaw thermal cycling resistance yog qhov tseem ceeb vim qhov kev ua tau zoo ntawm cov hlau tsis tu ncua {{14}n}S dissimilar hlau pob qij txha.
Puas yog 309S stainless hlau haum rau vuam sib txawv?
Yog lawm, 309S yog cov weldable heev thiab tshwj xeeb yog tsim los ua cov hlau muab tub lim rau kev sib txuas cov hlau sib txawv, tshwj xeeb tshaj yog rau vuam austenitic stainless hlau rau carbon lossis qis- alloy steels. Nws cov ntsiab lus siab alloy muab thaj tsam tsis tuaj yeem ua kom haum rau qhov sib txawv thermal expansion coefficients thiab tiv thaiv kev tsiv teb tsaws ntawm carbon hlau los ntawm cov hlau tsis muaj steel. Nws kuj yog dav siv rau stainless hlau cladding ntawm carbon steel Cheebtsam nyob rau hauv lub siab hlab ntsha thiab cov txheej txheem khoom. Nws cov ntsiab lus carbon tsawg txo qis carbide nag lossis daus hauv tshav kub- cuam tshuam thaj chaw, ua kom muaj kev tiv thaiv corrosion zoo hauv qhov sib koom ua ke.
