Tus nqi nruab nrab ntawm cov ntawv txias-dov 409L stainless hlau feem ntau yog nyob nruab nrab ntawm $ 1.50 thiab $ 2.80 ib kilogram (kwv yees li $ 1,200 mus rau ntau tshaj $ 2,500 ib tuj) nyob rau xyoo 2025 thiab thaum ntxov 2026. Cov nqi hloov pauv raws li thickness, tsum, thiab kev lag luam xav tau; Cov ntawv nyias nyias nyias (0.5-3.0 hli) feem ntau yog nyob rau sab sauv kawg ntawm qhov ntau.
5 yam tseem ceeb cuam tshuam tus nqi ntawm 409L
1️⃣ Cov nqi raw khoom
Kev hloov pauv hauv cov hlau ore thiab cov nqi ferrochrome ncaj qha cuam tshuam cov nqi hauv paus. Txij li nws tsis muaj npib tsib xee, nws tus nqi zoo li ruaj khov dua piv rau 304 stainless hlau.
2️⃣ Txias dov cov nqi
Qhov siab dua qhov yuav tsum tau ua rau txias dov ntawm 409L stainless hlau los xij, tus nqi siab dua. Tsis tas li ntawd, cov txheej txheem ntawm thinner gauges (<1 mm) plantea mayores desafíos de fabricación.
3️⃣ Nto tiav
Tus nqi ntawm 409L stainless hlau los xij nrog BA lossis 8K daim iav tiav yog qhov siab dua li cov ntawv txheeb nrog tus qauv 2B tiav; Kev lag luam tsheb, tshwj xeeb tshaj yog, feem ntau xav tau qhov siab ntawm qhov sib xws.
4️⃣ Kev yuav ntim (Qhov cuam tshuam ntawm MOQ)
Cov me me: Cov nqi yuav raug rau 5% mus rau 15% markup (khoom kim heev).
Kev txiav txim rau cov phiaj xwm loj: Cov nqi qis tuaj yeem sib tham.
5️⃣ Daim ntawv pov thawj thiab cov qauv
ASTM A240 / EN 1.4512 / JIS SUS409L; Kev lag luam tsheb kuj tseem yuav xav tau IATF 16949 ntawv pov thawj.
Qhov txawv ntawm 409 thiab 409L yog dab tsi?
Qhov siab tshaj carbon ntsiab lus ntawm 409L yog 0.03%, thaum cov ntsiab lus carbon ntawm tus qauv 409 tuaj yeem siab dua. Rau cov ntaub ntawv txias dov, 409L yog qhov kev xaiv zoo dua; Qhov no yog vim tias nws cov ntsiab lus qis dua txhim kho ob qho tib si nws cov weldability thiab nws tsis kam mus rau intergranular corrosion, ob yam tseem ceeb uas yog qhov tseem ceeb rau kev tsim cov tsheb tso tsheb.
Tus nqi ntawm 409L piv rau 430 stainless hlau li cas?
409L thiab 430 feem ntau raug nqi zoo ib yam li lawv yog ob qho tib si nickel-free ferritic steels. Txawm li cas los xij, 430 feem ntau muaj cov ntsiab lus chromium ntau dua (16-18%) piv rau 409L (10.5-11.7%), ua rau 430 kim dua me ntsis tab sis zoo dua haum rau kev zoo nkauj lossis corrosion kuj, thaum 409L zoo dua rau kev siv cua sov lossis tso pa.
Tus nqi ntawm txias dov 430 stainless hlau daim ntawv tau qhia ib tug nruam upward trend, nce los ntawm RMB 7,500 / tuj nyob rau hauv Lub ib hlis ntuj mus rau RMB 7,735 / tuj nyob rau hauv lub Plaub Hlis, sawv cev ib tug tsub zuj zuj ntawm RMB 235 / tuj. Lub caij no, tus nqi ntawm cov ntawv txias-dov 409L stainless hlau tau ntsib qhov nce tas li ntawm Lub Ib Hlis thiab Lub Peb Hlis, tab sis raug kev poob qis hauv lub Plaub Hlis, poob ntawm 7,600 RMB / ton hauv lub Peb Hlis mus rau 7,550 RMB / ton.
