DX55D+AS120yog ib tug siab -kev ua tau zoo kub dip aluminized- silicon steel kauj, optimized rau automotive pa system Cheebtsam. Ua raws li DIN EN 10346 (cov ntaub ntawv naj npawb 1.0962) thiab ASTM A653 tus qauv, nws nta 120g / m² aluminium-silicon (+ AS) txheej (90% aluminium, 10% silicon) uas xa cov khoom tshwj xeeb siab - tiv thaiv qhov kub thiab txias (txog 10) qib siab tshaj (txog 8) formability.
DX55D + AS120 yog qhov zoo tshaj plaws rau cov uas tsis yog-welded, complex- zoo li cov khoom seem xws li cov ntaub thaiv npog, cov kav dej tso pa tawm, thiab cov pa hluav taws xob nruab nrab. Nws qhov tshwj xeeb ua ke ntawm formability, tshav kub tsis kam, thiab tus nqi-efficiency ua rau nws nyiam cov khoom siv rau cov tshuab hluav taws xob siv hluav taws xob, ntsuas kev ua tau zoo thiab kev tsim khoom lag luam thaum ua tau raws li cov qauv kev lag luam tsheb thoob ntiaj teb.
DX55D + AS120 yog qhov tshwj xeebsib sib zog nqus- kos duab qis- carbon steel kaujnrog lub kub-dipped aluminium-silicon (+AS) txheej, qhov "AS120" qhia txog txheej txheej hnyav ntawm 120g / m² (ob -sab), tsim cov alumina tuab tiv thaiv txheej ntawm qhov chaw. Cov txheej no yog tsim tshwj xeeb los daws qhov kev ua haujlwm hnyav ntawm lub tsheb tso pa tawm - tsis tu ncua raug kub siab (200℃-700℃thaum lub sijhawm ua haujlwm ib txwm, mus txog 800℃thaum lub sijhawm luv luv), corrosive pa gases (CO, NOx, sulfur oxides), thiab sab nraud cov ntsev, plua plav, thiab lwm yam.
Automotive tso tshuab xav tau cov ntaub ntawv uas sib npaug formability (rau complex shaping), siab - kub stability (kom tsis txhob coating delamination los yog cov khoom deformation), corrosion kuj (kom ntev kev pab cuam lub neej), thiab tus nqi -effectiveness (rau loj- teev ntau lawm). DX55D + AS120 ua tau raws li cov kev cai no, ua tau zoo tshaj cov hlau galvanized hauv siab - qhov kub thiab txias thiab muab cov kev daws teeb meem ntau dua li cov hlau tsis muaj steel 409 rau cov khoom tsis yog -welded. Raws li cov khoom siv tseem ceeb rau lub tshuab hluav taws xob tsheb, nws tau txais kev pom zoo los ntawm cov neeg tsim hluav taws xob thoob ntiaj teb rau nws qhov kev ua tau zoo thiab ua raws li IATF 16949 automotive zoo qauv.
Cov yam ntxwv tseem ceeb ntawm DX55D + AS120 Matching Automotive Exhaust System Xav Tau
Qhov kev ua tau zoo ntawm DX55D + AS120 yog ua tib zoo ua raws li cov kev xav tau ntawm kev ua haujlwm ntawm lub tshuab hluav taws xob, ua kom muaj kev ntseeg siab, ua haujlwm ntev, thiab kev tsim khoom:
1. Superior High -Tsub Resistance (Critical for Exhaust Environments)
Lub + AS120 txheej ntawm DX55D tsim cov txheej ruaj khov ternary alloy (txhuas- hlau- silicon) ntawm cov hlau- txheej txheej, uas tuaj yeem tiv taus luv luv - lub sijhawm kub siab txog 800℃thiab ntev -lub sijhawm kev pabcuam txuas mus ntxiv ntawm 650℃7 {{0}degree} ntau npaum li cas automotive tso tshuab (cov pa hluav taws xob hluav taws xob tawm mus txog 600℃-750 degree, cov kav dej nruab nrab thiab cov ntaub thaiv hluav taws xob ua haujlwm ntawm 200℃-600 degree). Tsis zoo li cov zinc ntshiab (+Z) txheej uas yaj ntawm 419 degree, aluminium-silicon txheej ntawm DX55D + AS120 tsis delaminate lossis oxidize nyob rau hauv qhov kub thiab txias, tswj kev ua haujlwm ruaj khov thiab kev tiv thaiv kev ua haujlwm. Tsis tas li ntawd, cov txheej txheej muaj qhov zoo ntawm cov hluav taws xob zoo heev (txog 80% lub teeb pom kev), uas yuav pab txo cov cua sov hloov mus rau lub cev ntawm lub tsheb, tiv thaiv cov khoom nyob ze (xws li, cov xov hlau, cov khoom yas) los ntawm cov thermal puas-qhov tseem ceeb ntawm cov khoom siv hluav taws xob.
2. Zoo heev Corrosion Resistance (Extending Exhaust Component Service Life)
Automotive cov khoom siv hluav taws xob ntsib ob qho kev hem thawj: kev tiv thaiv sab hauv los ntawm cov pa roj carbon monoxide (sulfur oxides hnov mob nrog dej los tsim sulfuric acid) thiab sab nraud corrosion los ntawm txoj kev ntsev, dej nag, thiab hmoov av. Lub + AS120 txheej ntawm DX55D tsim cov alumina tuab (Al₂O₃) zaj duab xis rau ntawm qhov chaw, uas yog inert thiab impermeable rau corrosive xov xwm, zoo cais lub hauv paus hlau los ntawm ib puag ncig hnyav. Qhov kev tiv thaiv corrosion no yog ob peb zaug siab dua li cov tsoos galvanized steel, thiab txawm tias piv rau qis -chromium stainless hlau (409) hauv qhuav, siab - qhov kub thiab txias. Kev ntsuam xyuas qhia tau hais tias DX55D + AS120 cov khoom siv hluav taws xob muaj lub neej ua haujlwm ntawm 5-8 xyoo nyob rau hauv kev ua haujlwm ntawm lub tsheb, ua tau raws li kev lag luam tsheb qhov yuav tsum tau ua rau kev siv lub tshuab ua kom ntev (tsawg kawg 5 xyoos). Lub 120g / m² txheej hnyav ua kom cov tuab txaus los tiv thaiv kev hnav thiab corrosion thaum lub sij hawm siv ntev -, thaum lub sij hawm txhuas-silicon muaj pes tsawg leeg tiv thaiv qhov "dawb xeb" qhov teeb meem tshwm sim nyob rau hauv cov ntshiab zinc txheej.
3. Exceptional Formability (Adapting rau Complex Exhaust Component Shapes)
Cov khoom siv hluav taws xob hauv tsheb xws li cov ntaub thaiv cua sov, lub tsho tso pa tawm, thiab cov khoom sib txuas nruab nrab feem ntau muaj cov nkhaus nkhaus, sib sib zog nqus- cov duab kos, xav tau cov ntaub ntawv nrog txias txias- kev ua tau zoo. DX55D yog qhov tshwj xeeb sib sib zog nqus- qib kos duab nrog lub zog tawm ntawm 140-240 MPa, tensile lub zog ntawm 270-370 MPa, thiab elongation (A80) ntawm Ntau dua lossis sib npaug li 30%, kom ntseeg tau tias tsis muaj kev sib sau ua haujlwm thiab tsis muaj kev sib tsoo thaum lub sij hawm tawg. Cov txheej + AS120 muaj qhov zoo ductility, uas synchronously deforms nrog lub hauv paus hlau thaum lub sij hawm tsim tsis tev los yog cracking - kov yeej cov teeb meem ntawm txheej brittleness nyob rau hauv tsoos siab - kub txheej. Qhov formability no tso cai rau cov tuam txhab tsim cov khoom ua kom zoo li cov khoom siv hauv ib txheej txheem stamping, txo cov qib ntau lawm thiab cov nqi. Piv rau stainless hlau 409 (uas muaj kev ua haujlwm tsis zoo txias thiab ua rau tawg), DX55D + AS120 yog qhov tsim nyog rau kev tsim khoom loj ntawm cov khoom siv hluav taws xob.
4. Tus nqi-Kev ua tau zoo (Sib npaug Kev Ua Haujlwm thiab Kev Lag Luam Kev Lag Luam)
Raws li qis- carbon steel nrog kub-dipped aluminium-silicon txheej, DX55D + AS120 yog 30%-50% pheej yig dua stainless hlau 409, thaum ua tau raws li qhov yuav tsum tau ua ntawm feem ntau tsis yog -welded pa Cheebtsam. Rau cov neeg caij tsheb loj thiab cov tsheb ua lag luam, qhov kev tswj hwm tus nqi yog qhov tseem ceeb, DX55D + AS120 muab qhov zoo tshaj plaws sib npaug ntawm kev ua tau zoo thiab tus nqi- tshem tawm qhov xav tau ntawm cov khoom siv hlau tsis zoo rau cov khoom tsis yog - cov pa roj tseem ceeb. Tsis tas li ntawd, cov txheej txheem tsim khoom yooj yim ntawm DX55D + AS120 (kub dip txheej) ua kom cov khoom ruaj khov thiab kev xa khoom luv luv, hloov mus rau qhov kev xav tau ntau ntawm cov khoom siv tsheb. Nws compatibility nrog uas twb muaj lawm stamping thiab tsim cov cuab yeej kuj txo cov tuam txhab kev nqis peev hauv cov kab ntau lawm.
5. Ua raws li cov qauv kev lag luam Automotive
DX55D + AS120 ua raws li cov qauv thoob ntiaj teb xws li DIN EN 10346, ASTM A653, thiab IATF 16949 (automotive quality management system), kom ntseeg tau tias zoo ib yam thiab kev ua tau zoo ntawm cov khoom siv. Nws kuj ua tau raws li ib puag ncig cov cai ntawm RoHS thiab REACH, ua rau nws tsim nyog rau kev lag luam tsheb thoob ntiaj teb. Cov khoom siv tau dhau qhov kev ntsuam xyuas kev lag luam tsheb nruj, suav nrog qhov siab -kub cycling, corrosion resistance (salt spray test), thiab formability tests, paub meej tias nws muaj kev ntseeg siab nyob rau hauv daim ntawv thov tso pa. Nws cov qib sib npaug (piv txwv li, JIS G 3302 SGCH + AS, GB / T 2518 DC55D + AS120) ua kom muaj kev sib raug zoo nrog cov qauv tsim tsheb hauv cheeb tsam.
