Xaiv Stainless Hlau 409 yog: Koj xav tau ntev -lub sij hawm siab- qhov kub thiab txias (kev pabcuam txuas mus ntxiv ntawm 600℃-700 degree), yooj yim corrosion kuj, lossis welded Cheebtsam (xws li, cov kav dej tso tawm).
Cov lus nug nquag nug (FAQ)
1. Dab tsi yog qhov txawv ntawm DX55D thiab Stainless Hlau 409?
Qhov sib txawv tseem ceeb yog cov khoom siv thiab cov khoom siv tiv thaiv corrosion: DX55D yog qis- carbon steel nrog + AS txheej (kev tiv thaiv corrosion los ntawm txheej, superior formability, qis nqi). Stainless hlau 409 yog ferritic stainless hlau (corrosion kuj los ntawm chromium, zoo dua ntev - lub sij hawm siab - kub stability, siab zog).
2. Qhov twg zoo dua siab dua -kub tsis kam?
DX55D muaj qhov zoo dua luv luv- lub sij hawm siab - kub tsis kam (txog 800℃), hos Stainless Steel 409 muaj qhov zoo dua ntev - lub sij hawm ruaj khov (kev pabcuam txuas mus ntxiv ntawm 600℃-700℃). Rau luv-lub sij hawm raug tshav kub (piv txwv li, qee zaus siab-temp spikes), DX55D zoo dua; rau kev pab cuam thermal mus sij hawm ntev (xws li, cov kav dej tso tawm), 409 yog superior.
3. Qhov twg yog tus nqi ntau dua - zoo rau daim ntawv thov loj -?
DX55D yog tus nqi ntau dua -zoo, vim nws yog 30%-50% pheej yig dua Stainless Hlau 409. Nws yog qhov zoo tagnrho rau loj- nplai ntau lawm qhov twg formability thiab luv-lub sij hawm kub-kub kuj yuav tsum tau, thiab corrosion raug tsawg heev.
4. DX55D puas tuaj yeem hloov Stainless Hlau 409 hauv cov pa tawm?
Tsis yog. Stainless Steel 409 yog tsim los rau ntev -lub sij hawm tas mus li siab- qhov kev pab cuam kub (cov kav dej, cov mufflers) nrog rau qhov kev tiv thaiv corrosion. DX55D's + AS txheej tuaj yeem delaminate nyob rau hauv qhov kub siab ntev, thiab nws cov hlau hauv paus yuav xeb yog tias txheej puas lawm.
5. Uas muaj zoo formability rau complex Cheebtsam?
DX55D muaj cov qauv zoo tshaj plaws, nrog lub zog qis zog (140-}240 MPa) thiab siab dua elongation (Ntau dua lossis sib npaug li 30%), ua rau nws tsim nyog rau kev sib sib zog nqus nqus thiab cov khoom nkhaus (piv txwv li, cov ntaub thaiv hluav taws xob). Stainless hlau 409 muaj kev ua haujlwm tsis zoo rau kev ua haujlwm txias thiab ua rau tawg thaum lub sijhawm ua haujlwm nyuaj.
