409L Stainless hlau vs . 304: Tus nqi
409L stainless hlau muaj 30-40% tus nqi kom zoo dua piv rau 304 (tam sim no tus nqi ntawm 14.20 RMB / kg rau txias dov). Tus nqi yuav tsum nyob twj ywm hauv qhov nqaim ntawm 6.80-7.80 RMB / kg thaum lub quarter thib ib ntawm 2026, cuam tshuam los ntawm cov khoom siv xws li cov nqi raw khoom (chromium: US $ 8.5-9.0 / kg, titanium: US $ 35-38 / kg) thiab kev thov los ntawm kev lag luam tsheb (nws lub ntsiab daim ntawv thov 5, suav txog 6%).

 

Dab tsi yog409L Stainless Hlau Sheet?

409L stainless hlau yog ferritic qis -carbon stainless hlau nrog 10.5-11.5% chromium thiab Tsawg dua lossis sib npaug rau 0.03% carbon. Nws cov ntsiab lus carbon tsawg txo qis carbide nag lossis daus thaum lub vuam, ua rau nws zoo tagnrho rau cov tsheb siv hluav taws xob, kev lag luam ducting, thiab kev siv cov txheej txheem uas yuav tsum tau muaj kev tiv thaiv corrosion ntawm tus nqi - tus nqi zoo.

Cov yam ntxwv tseem ceeb:

Sib nqus ferritic qauv

Zoo weldability thiab formability

Nruab nrab corrosion kuj

Tus nqi -tshwj xeeb zoo rau 430 stainless hlau hauv qee daim ntawv thov.

Yuav ua li cas 409L piv nrog 430 stainless hlau nyob rau hauv corrosion kuj?
409L stainless hlau muaj kev tiv thaiv qis dua li 430 stainless hlau nyob rau hauv ib puag ncig, tab sis muab kev tiv thaiv txaus rau oxidation thiab me ntsis corrosion, ua rau nws tsim nyog rau kev siv tsheb tso tsheb.

 

Dab tsi thicknesses thiab dav muaj rau 409L ntawv?
409L stainless hlau nplooj ntawv feem ntau muaj nyob rau hauv thicknesses xws li 0.4 hli mus rau 6 hli thiab txheem dav txog li 1,500 hli, nrog rau kev cai ntau thiab tsawg muaj raws li thov.

 

409L stainless hlau ntawv puas tuaj yeem siv rau kev siv lub tshuab hluav taws xob?
Yog lawm, 409L stainless hlau los xij yog siv dav hauv cov tsheb siv hluav taws xob vim lawv qhov zoo siab -kub oxidation tsis kam, tus nqi- ua tau zoo, thiab muaj peev xwm tsim cov duab nyuaj.

 

Puas yog 409L stainless hlau sib nqus?

409L stainless hlau yog hlau nplaum vim nws yog ferritic stainless hlau, uas tso cai rau nws khaws cov khoom sib nqus txawm tias tom qab vuam lossis sib sau.
