Cov qhab nia xaiv tau
- Rau cov khoom siv hluav taws xob nyob hauv nruab nrab mus rau sab nraub qaum ntawm lub tsheb, qhov ntev - lub sijhawm ua haujlwm kub tsis tshaj 600℃, 304/304L stainless hlau yog qhov kev xaiv tsim nyog vim nws yog tus nqi ntau dua - zoo dua 321.
- Rau huab hwm coj- cov khoom tsim xws li cov kav dej tso tawm, cov khoom siv catalytic converter vaj tse, mufflers, thiab diesel cav tso qhov chaw, 409 stainless hlau yog ib qho kev xaiv zoo vim nws tus nqi qis thiab zoo oxidation kuj.
- Rau cov tailpipe seem feem ntau raug rau saline de{0}} cov neeg ua haujlwm icing lossis cov chaw nyob ib puag ncig ntawm ntug dej hiav txwv, 316L stainless hlau raug pom zoo, vim nws muaj qhov zoo tshaj pitting corrosion kuj piv rau 321.

FAQ
Q: Dab tsi yog qhov sib txawv ntawm ASTM A213 TP321 thiab cov kav dej zoo nkauj 304 pom hauv khw?
A: Hom 304 cov kav dej feem ntau yog siv rau hauv qab ntu lossis lub hom phiaj zoo nkauj; lawv muaj tsawg siab - kub lub zog thiab muaj kev cuam tshuam rau intergranular corrosion tom qab vuam. Nyob rau hauv sib piv, A213 TP321 yog siv rau ua ntej -turbo seem raug kub mus txog 1,000℃; nws tiv thaiv ncej-weld corrosion thiab muaj ntau dua 40% ntev dua -lub sij hawm lub zog.
Q: Puas yog 321 stainless hlau tso cov kav dej tuaj yeem khoov?
A: Yog lawm . 321 stainless hlau muaj qhov zoo ductility (elongation Ntau dua lossis sib npaug li 35%), ua rau nws haum rau kev khoov txias.
Q: Dab tsi yog qhov siab tshaj plaws ua haujlwm kub rau cov yeeb nkab no?
A: Qhov kev pom zoo ua haujlwm tsis tu ncua rau 321 stainless hlau (nyob rau hauv cov nqe lus ntawm oxidation kuj) yog 816 degree, nrog kev pab cuam sib tshuam txog 870 degree. Nws qhia tau hais tias muaj zog creep zoo heev thiab thermal qaug zog lub neej nyob rau hauv 600-750℃ntau yam ntawm cov pa manifolds.
