Puas yog koj tab tom nrhiav rau txias dov 409L stainless hlau coils rau kev siv tsheb, tab sis tseem ntsib teeb meem xws li tsis xwm yeem thickness, tsis zoo formability los yog tsis ruaj tsis khov nto zoo thaum lub sij hawm ntau lawm? Qhov sib txawv tiag tiag yog nyob rau hauv kev ua haujlwm ruaj khov, qhov tseeb qhov tseeb thiab cov khoom sib xws.
GNEE, nrog ntau tshaj 18 xyoo ntawm kev paub hauv kev muab cov hlau stainless coils, tau xa cov khoom zoo rau ntau tshaj 50 lub teb chaws thiab cheeb tsam, nrog rau txhua xyoo xa tawm ntau tshaj 2,000 tons. Peb lav tag nrho cov ntaub ntawv traceability thiab zoo ib yam nyob rau hauv txhua batch, ua rau peb ib tug txhim khu kev qha khub rau automotive manufacturers.
Peb to taub meej tias qhov kev pheej hmoo loj tshaj plaws nrog 409L coils yog batch-to-batch inconsistency. Yog tias qhov elongation tsis txaus, cov kab nrib pleb yuav tshwm sim thaum khoov; Yog tias cov ntsiab lus titanium (Ti) tsis ruaj khov, qhov no tuaj yeem ua rau cov welds tsis muaj zog thiab corrosion ntawm cov pob qij txha, uas tuaj yeem ua rau tag nrho cov kab ntau lawm. Yog li ntawd, peb nruj me ntsis tswj tias cov ntsiab lus Ti yog ntau dua los yog sib npaug rau 6 × (C + N) thiab peb tuav ib tug elongation Ntau tshaj los yog sib npaug li 25%, kom ruaj khov txhua yam khoom thiab ua rau peb cov khoom zoo tagnrho rau stamping, dabtsi yog khoov thiab vuam txheej txheem yam tsis muaj kev pheej hmoo ntawm tawg.
Nyob rau hauv cov nqe lus ntawm thickness raug, peb nruj me ntsis tswj tolerances nyob rau hauv lub ntau yam ntawm ± 0.02 rau ± 0.03 hli, kom ntseeg tau ib tug uniform thiab tas li thickness thoob plaws hauv tag nrho cov kauj, thaum ua kom burr theem kom tsawg kawg nkaus. Peb 409L coils muaj nrog 2B lossis BA nto tiav; Nto roughness feem ntau tswj tau rau Ra tsawg dua lossis sib npaug ntawm 0.5-0.8 μm, thiab cov khoom siv tsis muaj khawb, zeb kos lossis oxidation tsis xws luag.
Peb muaj kev paub dhau los hauv cov khoom siv mus sij hawm ntev rau cov khoom siv hluav taws xob tso tawm, thiab nkag siab tag nrho cov kev xav tau ntawm 409L steel nyob rau hauv qhov kub thiab txias. Peb cov ntaub ntawv qhia kev txhim khu kev tiv thaiv oxidation ntawm qhov kub txog li 800 degrees, thiab peb tuaj yeem muab cov ntaub ntawv qhia txog kev ntsuas kub ntawm lwm tus neeg los txhawb koj daim ntawv thov.

409 vs 409L Stainless hlau: Qhov twg zoo dua rau kev lag luam tsheb?
409L stainless hlau feem ntau haum rau kev lag luam tsheb niaj hnub no -tshwj xeeb tshaj yog rau cov tshuab tso pa- vim tias nws cov ntsiab lus qis dua muaj qhov zoo tshaj plaws weldability thiab qis dua kev pheej hmoo ntawm corrosion ntawm welded pob qij txha piv rau cov qauv 409 steel. Thaum ob qho tib si yog tus nqi-zoo, kub-resistant ferritic steels, 409L muab cov qauv zoo dua qub hauv cov ntawv siv kub.
Nqe ib tuj ntawm 409L stainless hlau coils
Thaum pib ntawm 2026, tus nqi rau 409/409L stainless hlau coils feem ntau muaj li ntawm USD 1,000 txog USD 1,800 ib tuj, feem ntau cuam tshuam los ntawm qib specification, thickness, nto tiav thiab txiav ntim ntim.
Cold dov coils feem ntau yog nyob rau ntawm qhov kawg siab ntawm tus nqi ntau, thaum kub dov coils feem ntau nyob rau hauv qis kawg.
Vim hais tias ferritic stainless hlau tus nqi yog ze ze rau cov nqi ntawm chromium (Cr) thiab stainless hlau seem, nws raug nquahu kom thov ib qho kev hloov kho FOB nqe lus raws li koj qhov ntev, qhov chaw tiav thiab qhov xav tau kom muaj nuj nqis.
Tau tus nqi ntawm 409L Stainless Hlau Coils
Cov ntaub ntawv
ASTM A240/A240M: Txheem Specification rau Chromium thiab Chromium-Nickel Stainless Steel Sheet, Sheet, thiab Sawb (409, 409L).
TS EN 10088 Cov hlau tsis muaj steel - Ntu 1: Cov npe ntawm cov hlau tsis muaj steel (1.4512).
JIS G4305: Cold dov stainless hlau daim hlau, nplooj ntawv thiab sawb (SUH409L).
WorldAutoSteel / Exhaust System Materials Technical Literature: Cov ntaub ntawv qhia txog ferritic qib 409/441 siv nyob rau hauv automotive exhaust systems.
Yuav Ua Li Cas Thaum Yuav 409L Stainless Hlau Coils
1. Kev sib txuam ntawm cov khoom siv (qhov kev pheej hmoo loj tshaj plaws)
Tsis txaus elongation ua rau tawg thaum lub sij hawm khoov; Cov ntsiab lus titanium tsis ruaj khov ua rau tsis muaj zog welds thiab sib koom ua ke, uas tuaj yeem nres tag nrho cov kab ntau lawm. Paub meej ntawm txhua qhov khoom xa tuaj:Ti Ntau dua lossis sib npaug ntawm 6 × (C + N), elongation Ntau dua lossis sib npaug li 20-25%, thiab qhov nyuaj tas li nyob rau hauv tib lub tshav kub.
2. Thickness thiab profile kam rau ua
Rau cov khaub thuas dov sawb, ib qho kev lag luam kam rau siab yog± 0.03 ~ 0.05 hlisaum toj nominal thickness (qhov tseeb tus nqi nyob ntawm qhov dav thiab lub peev xwm ntawm lub dov zeb; paub meej tias qhov kev cog lus kam rau ua hauv koj daim ntawv xaj (PO)). Covcrown, ntug poob thiab burr theemlawv yuav tsum tau teev tseg; Burr-dawb npoo tiv thaiv yob txoj kev cov cuab yeej (yob txoj kev tooling).
3. Nto zoo
Cov tiav2B lub BALawv yog cov qauv rau coils npaj rau lub tshuab tso pa. Paub meej tias nto roughnessRa(ib txwmTsawg dua lossis sib npaug li 0.5-0.8 μm rau 2B tiav), qhov tsis muaj khawb, cov qhab nia ntawm cov menyuam thiab oxidation tsis xws luag, nrog rau kev tiv thaiv ntim khoom tsim nyog rau kev xa khoom thoob ntiaj teb.
4. Cov ntaub ntawv pov thawj los ntawm kev ntsuas kub
Rau cov ntaub ntawv qib qib collector (manifold- cov ntaub ntawv qib), thov oxidation kuaj cov ntaub ntawv ua los ntawm cov neeg sab nrauv uas txhawb kev pabcuam rau800 degrees, tsis yog tsuas yog lees txais cov lus qhia dav dav los ntawm cov chaw tsim khoom.
Ntim thiab shipping
Ntim: Txhua lub phaj lossis coil yog qhwv hauv daim ntawv tsis muaj dej noo, npog nrog zaj duab xis yas thiab ruaj nrog steel strapping. Cov txheej txheej sab nrauv yog tiv thaiv los ntawm cov pallets lossis cov thawv ntoo kom muaj kev nyab xeeb thaum caij tsheb mus los thoob ntiaj teb.
Labeling: Txhua pob muaj cov ntaub ntawv hais txog tus lej cam khwb cia, qib, qhov ntev thiab cov qauv siv tau.
Lub sij hawm xa tuaj: Feem ntau 7-15 hnub ua haujlwm thaum tau txais cov nyiaj them ua ntej.
Shipping txoj kev: Kev thauj mus los hauv hiav txwv (FCL / LCL), huab cua thauj lossis xa tawm, raws li cov neeg siv khoom xav tau.
