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.
