Cov blog no muab cov lus qhia ntxaws ntxaws ntawmASTM A213 SS310S Yeeb NkabCov lus qhia tshwj xeeb. Peb yuav delve rau hauv nws cov tshuaj muaj pes tsawg leeg, cov cuab yeej siv neeg, tsim cov qauv, thiab cov yam ntxwv tshwj xeeb.
Dab tsi yog SS310s (tsis yog S31008)?
SS310s, tseem paub los ntawm nws cov qauv sau tsis tseeb s31008, yog ib qho kev ua kom tsis muaj pa ntawm cov hlau uas muaj ntxhiab rau nws cov kev tiv thaiv zoo rau oxidation thiab corrosion ntawm qhov kub. Nws yog qhov tseem ceeb qhov tsawg - cov pa roj carbon version ntawm cov theem pib 310 alloy.
Qhov "s" hauv 310s kos npe nws cov ntsiab lus muaj cov roj carbon tsawg, uas txo cov kev sim siab rau carbide nag thiab corrosion tsis taus nyob rau hauv lub li - welded mob. Qhov no alloy kuj tseem hu ua "2520" stainless hlau, qhia txog cov muaj pes tsawg leeg ntawm 25% chromium thiab 20% npib tsib xee.
Cov yam ntxwv thiab cov txiaj ntsig zoo ntawm SS310S
Tshwj xeeb oxidation tsis kam:Lub siab chromium cov ntsiab lus tso cai rau SS310s los ua qhov ruaj khov, tiv thaiv cov roj chromium oxide tso rau ntawm lawv cov nplaim dej thaum raug kub.
Cov txheej no tiv thaiv cov hlau hauv qab ntawm cov roj oxidation txuas ntxiv, ua kom cov khoom siv tas mus li ntawm 1150℃thiab lub ncov siab mus txog 1200 degree.
Kev kub siab kub lub zog:SS310s khaws ib feem tseem ceeb ntawm nws lub zog ntawm kev nce kub. Nws muaj lub zog siab, uas yog cov khoom siv tiv thaiv kom deformation nyob rau hauv kev ntxhov siab ntawm kev kub ntxhov ntawm ncua sij hawm ntev. Thaum 1000 degree, nws tuaj yeem khaws tau kwv yees li 70% ntawm nws chav - lub zog.
Cov carburization zoo tsis kam:Qhov no ua yeeb yam ua tau zoo nyob rau hauv carbon - Cov pa hluav taws xob, los ntawm cov neeg pom hauv petrochemeres, los ntawm cov neeg pom hauv petrochemical cracking rauv rau cov pa roj carbon rau hauv cov hlau, uas tuaj yeem ua rau sawv xis.
Corrosion Kuj:Nws muaj zoo dav dav corrosion tsis kam, zoo dua rau qee tus neeg atustenitic hlau zoo li 304 thiab 309, tshwj xeeb tshaj tawm tawm tsam oxidizing cov kua qaub.
ASTM A213 Kev Ncaj Ncees rau SS310S
Lub ASTM A213 kev qhia tshwj xeeb yog tus qauv uas npog Seamless Ferritic thiab Austenitic Alloy {} {2} {2} {2}-} Cov raj tshav kub. Cov kav dej tsim rau cov qauv no tau npaj rau kev pabcuam hauv high- qhov siab thiab siab-}} kub ib puag ncig. Thaum ua ke nrog SS310 cov khoom siv, cov leeg ua los tsim yog ittm A213 TP313Ss.

Kev tsim thiab qhov ntev
Txheej txheej:ASTM A213 hlab yog seamless, lub ntsiab lus lawv yog tsim tawm los ntawm tho ib lub pob tawb uas tsis muaj welds. Cov txheej txheem no zoo tagnrho rau high- qhov kev siv siab, raws li nws tshem tawm txoj kab muaj peev xwm ntawm kev qaug zog.
Qhov loj loj:Cov kav dej no muaj nyob rau hauv ntau qhov sib txawv ntawm cov diameters, feem ntau yog los ntawm 6 hli mus rau 2500 hli (3/8 "rau 150 hli lossis raws li lub rooj sib tham phab ntsa.
Nto tas:Lub raj yog feem ntau muab nrog cov kab lossis annaled nto tas. Lwm qhov tag nrho zoo li polished lossis ci ci annealed tseem muaj rau cov ntawv thov uas yuav tsum tau ua kom huv si rau kev nyiam huv lossis ua kom zoo nkauj.
ASTM A213 TP310S Pipes Kev Siv
Vim yog lawv cov khoom muaj zog, ASTM A213 TP213
Lub zog tiam:Cov leeg Boiles, cov tsheb superasers, thiab siab - kub rov qab nyob rau hauv lub zog loj tiam, tshwj xeeb yog nyob ze - cov ntsiab lus tseem ceeb.
Petrochemical Kev Lag Luam:Tubing rau catalytic rov qab lub tshuab, nrws rauv taws leeg, thiab siab- kev hloov pauv kub.
Muaj Furnaces:Cheebtsam rau cov nplaim hluavtaws txaj, pulverized cov pob hluav taws kub tawg, cov kab kub cua sov, thiab lub raj rauv.
Lwm yam lag luam:Aerospace, metallurgy, thiab inciner systemer.
310s stainless hlau kub txwv
Hauv qab kev siv tas mus li, 310s Stainless hlau tuaj yeem tiv taus kub txog 1150 degree, thaum nyob rau hauv cov kev sib tw sib txawv, nws qhov chaw siab tshaj plaws tuaj yeem ncav 1100℃rau 1200 degree.
Qhov no zoo heev kev tiv thaiv yog feem ntau vim yog nws cov siab chromium thiab nickel cov ntsiab lus ntawm cov kub, yog li muab cov tshuaj tiv thaiv kab mob siab, yog li muab cov tshuaj tiv thaiv oxidation thiab nkag.
Nws yog ib qho tseem ceeb kom nco ntsoov tias ntev ntev siv nyob rau hauv kub ntau ntawm 425℃{{1}℃tej zaum, cuam tshuam nws cov kev ua tau zoo hauv qee qhov chaw muaj kev sib haum xeeb;
Tsis tas li ntawd, nws txoj kev ua tau zoo yuav ua rau tsis txaus rau hauv cov cua nab uas muaj txo cov roj sulphur uas muaj roj.
Yog li ntawd, nws yog dav siv nyob rau hauv high - kev sib pauv cua, muaj cov tshuab hluav taws xob, thiab cov roj muaj cov khoom siv Petrochemical.
Yuav Ua Li CasTswj 310S Stainless Hlau Yeeb?
Kev tu tu thiab tu kom tu ncua
Kev tu lub hom phiaj tu ncua kom tshem tawm cov khoom qias neeg saum npoo thiab tswj nws txoj kev ncaj ncees. Niaj hnub ntxuav tau ua tau nrog xab npum thiab dej thiab daim ntaub mos muag. Rau cov tawv ncauj organic storms, ib qho dej cawv me me tuaj yeem siv.
Tom qab tu, nco ntsoov yaug lub ntsej muag kom huv si nrog dej huv thiab ua kom nws qhuav nrog cov ntaub mos muag kom tiv thaiv dej. Tsis txhob siv cov cuab yeej abrasive xws li cov ntaub plaub hlau, vim tias qhov no yuav khawb cov yeeb yaj kiab tiv thaiv nyob saum npoo.
Welded pob qij txha
Welded pob qij txha yog lub ntsiab tseem ceeb thiab tsis muaj zog nyob rau hauv kev saib xyuas ntawm 310s stainless hlau kav hlau. Thaum lub sij hawm vuam, xyuas kom muaj kev siv siab- Cov pa roj kev tiv thaiv roj rau sab hauv los tiv thaiv cov pa hluav taws xob rov qab los tiv thaiv kev kub ntxhov thiab kev sib daj sib cais ntawm Weld cag.
Txog ua tiav Welds, tshaj tawm {- Weld kev kho mob los ntawm tshav kub- cuam tshuam cheeb tsam thiab kho nws txoj kev tiv thaiv corrosion. Yog tias muaj qhov tsis xws luag xws li macroscopic tau pom nyob hauv Weld, nws yuav tsum tau cim thiab rov ua {welded tam sim ntawd.
Corrosion tiv thaiv
310 30s Stainless hlau kav tseem yuav tsum muaj kev tiv thaiv corrosion hauv qee qhov chaw ib puag ncig. Nyob rau hauv high {- qhov chaw ib puag ncig muaj cov chloride muaj cov tshuaj chloride muaj cov txheej txheem tshwj xeeb, ib qho tshwj xeeb tiv thaiv yuav tsum tau txiav txim siab.
Cov txheej txheem xaiv txheej txheej yuav tsum tau tiv thaiv qhov kub thiab muaj kev sib raug zoo nrog cov hlau stainless.
Tsim Ny Cia
310 30s Cov kav dej stainless hlau yuav tsum muab cia rau hauv ib puag ncig ntoo, tsis txhob sib chwv ntawm cov nroj tsuag ntoo lossis lwm yam hlau los tiv thaiv cov roj carvanic.
Yog tias cov kav dej yuav tsum tau tawm ntawm kev pabcuam rau ncua sijhawm, nws yuav tsum tu huv si, kom qhuav, thiab sib khi. Qhov no tuaj yeem ua tiav los ntawm kev ntxuav tawm nrog cov roj hauv cov roj xws li cov nitrogen qhuav.
