Thaum nws los txog rau xaiv txoj cai stainless hlau rau automotive tso cov kav dej, ob ntawm cov khoom feem ntau suav hais tias yog SUS304 thiab SUS409 stainless hlau. Ob cov ntaub ntawv muaj cov khoom tshwj xeeb uas ua rau lawv haum rau kev siv sib txawv, tab sis kev nkag siab txog lawv qhov sib txawv yog qhov tseem ceeb thaum xaiv cov khoom siv zoo tshaj plaws rau koj qhov tso pa tawm.
Dab tsi yog SUS304 stainless hlau?
SUS304 (tseem hu ua AISI 304) yog cov feem ntau siv austenitic stainless hlau, paub txog nws zoo heev corrosion kuj, lub zog, thiab formability. Nws muaj 18% chromium thiab 8% npib tsib xee, uas ua rau nws muaj zog corrosion kuj thiab ua rau nws haum rau ntau yam siab - kub daim ntawv thov. Nws yog dav siv nyob rau hauv ntau yam industries, xws li automotive, zaub mov ua, thiab tshuaj industries, uas yuav tsum tau siab corrosion kuj thiab lub zog.
SUS409 stainless hlau yog dab tsi?
SUS409 yog ferritic stainless hlau muaj li ntawm 10.5% mus rau 11.75% chromium, nrog cov ntsiab lus qis nickel tshaj SUS304. Nws muaj qhov zoo oxidation tsis kam thiab ua rau me me corrosion ntawm qhov kub thiab txias, tab sis nws cov corrosion kuj tsis zoo li SUS304. Vim nws pheej yig thiab siab -kub tsis kam, SUS409 feem ntau yog siv nyob rau hauv tsheb tso tsheb. Txawm hais tias nws cov corrosion kuj tsis zoo li SUS304, nws ua tau zoo nyob rau hauv ib puag ncig nrog oxidation thiab me ntsis corrosion.
Qhov sib txawv tseem ceeb ntawm SUS304 thiab SUS409 Stainless hlau rau cov kav dej
| Khoom | SUS304 Stainless hlau | SUS409 Stainless hlau |
|---|---|---|
| Corrosion Resistance | Kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv siab -cov av noo thiab oxidizing ib puag ncig. | Zoo corrosion kuj, tab sis tsis siab li SUS304. |
| Thaum tshav kub kub Resistance | Cov cua kub zoo heev, tuaj yeem tiv taus kub txog 870℃(1600℃F). | Cov cua kub zoo, tiv taus mus txog 850℃(1562℃F). |
| Durability | Muaj kev ruaj khov thiab ntev -ntev, zoo tagnrho rau qhov chaw hnyav. | Durable, tab sis zoo dua haum rau cov ntawv thov tsawg dua. |
| Nqi | Tus nqi siab dua vim muaj cov ntsiab lus alloy ntau dua (nickel). | Tus nqi pheej yig dua, feem ntau siv rau tus nqi - cov ntawv thov nkag siab. |
| Weldability | Yooj yim rau weld thiab daim ntawv, haum rau cov duab complex. | Yooj yim rau welding tab sis yuav tsum tau ceev faj tswj cov cua sov. |
| Daim ntawv thov | Exhaust systems, khoom noj khoom haus, tshuaj industries. | Feem ntau siv nyob rau hauv automotive tso tshuab, mufflers, kav. |
SUS304 vs SUS409 Stainless Steel Exhaust Pipes: nqe
| Khoom | SUS304 Stainless hlau | SUS409 Stainless hlau |
|---|---|---|
| Cov yeeb nkab (1.5" - 2") | $5.50 - $7.00 ib kg | $3.20 - $4.50 toj ib kg |
| Cov yeeb nkab (2" - 4") | $5.80 - $7.20 toj ib kg | $3.50 - $5.00 ib kg |
| Custom Exhaust Pipe (Different Diameters) | $5.60 - $7.10 toj ib kg | $3.30 - $4.80 toj ib kg |
| Muffler & Exhaust Components | $6.00 - $7.50 toj ib kg | $3.60 - $5.30 toj ib kg |
Vim li cas thiaj xaiv SUS409 stainless hlau ua cov khoom siv yeeb nkab?
SUS409 stainless hlau raug xaiv los ua cov khoom siv hauv cov yeeb nkab vim tias, thaum ua tau raws li qhov yuav tsum tau ua kom siab ntxiv -kub oxidation tsis kam ntawm 600-750 degree, nws cov npib tsib xee-dawb muaj pes tsawg leeg muab 15-25% tus nqi kom zoo dua. Qhov no ua rau nws tus nqi ntau dua -zoo dua li austenitic stainless hlau zoo li 304 hauv cov ntawv thov uas xav tau kev tiv thaiv tshav kub, kev tiv thaiv corrosion tsis zoo, thiab tus nqi rhiab heev, xws li cov tshuab hluav taws xob tsheb (mufflers, catalytic converter vaj tse).
