Yog tias koj tab tom nrhiav rau cov ntawv pheej yig stensless nrog zoo corrosion zoo, muaj kev tiv thaiv tshav kub thiab sib nqus, qib 40 yog qhov kev xaiv zoo. Xyoo 2025, lub ntiaj teb xav tau kev thov rau Ferritic stainless cov ntawv xws li 409 yog nce, tshwj xeeb yog nyob hauv lub tsheb thiab lub zog sectors.
Vim yog tus nqi nce ntawm npib tsib xee, muaj ntau cov tuam ntxhab tau tshawb rau npib tsib xee-dawb 409 daim ntawv yuav txo cov nqi ntau lawm. Cov ntawv no tau siv dav hauv kev nqus tsev, catalytic converter tsev thiab kev sib pauv cua sov, uas yog qhov ua kom corrosion tsis kam thiab muaj zog hlau nplaum. At GNEE, prices for 409 sheet vary between $2.10 – $2.80 USD/kg, depending on thickness, surface finish and order quantity.
Yog 409 stainless hlau ntawv sib nqus?
Yog lawm, 409 stainless hlau ntawv sib nqus. Hom 409 belongs rau tsev neeg Ferritic, muaj kwv yees li 11-12% chromium thiab me me tsib xee. Nws lub cev kaw lus cubic (BCC) cov qauv siv lead ua muab cov khoom sib nqus muaj zog, txawm tias tom qab kev kho cua sov.
Kev sib nqus tus cwj pwm ntawm 409 ua rau nws yooj yim kom paub thiab muaj txiaj ntsig zoo nyob rau qhov twg cov lus teb sib nqus, xws li cov tshuab hloov tsheb sib nqus, thiab cua sov.

Corrosion Kuj
409 STEEL muajKev tiv thaiv zoo heev rau cov pa roj teeb thiab cov pa hluav taws xob corrosion, zoo dua 410 martensitic steel nrog 12% chromium. Txawm li cas los xij, nws txoj kev tawm tsam yog qis dua li ntawmQeb 430nrog 17% chromium. Saum npoo ntawm 409 yuav nthuav tawmLub teeb corrosion, txwv nws siv hauv cov ntawv thov dai.
