Dab tsi yog qhov sib txawv ntawm 1.4541 thiab 1.4404 cov kav dej stainless hlau?
Tso lus
Thaum xaiv cov kav hlau stainless hlau rau cov neeg xav tau ib puag ncig, tshwj xeeb tshaj yog hauv kev lag luam siv, kev lag luam khoom noj, lossis kub ntau dua, cov neeg yuav khoom sib pivEn 1.4541 (AISI 321) thiabEn 1.4404 (AISI 316L){{0. Thaum ob qho tib si yog Antenenitic Stainless hlau, lawv muab cov txiaj ntsig sib txawv nyob ntawm cov ntawv thov.
1.4541 vs1.4404 Stainless Hlau:
| Teem nqi | En 1.4541 | En 1.4404 |
|---|---|---|
| Ib tug aisi | 321 | 316L |
| Tsis yog | S32100 | S31603 |
| Sib ntxaws | CR-ni + Titanium Streticized | Cr-ni-mo, tsawg-carbon |
Dab tsi yog qhov sib txawv ntawm 1.4541 thiab 1.4404 Stainless hlau?
1. Corrosion Kuj
1 {. 4404 / 316l SS hloov yeeb nkab muaj cov yeeb nkab hloov tshiab thiab cov kua qaub vim nws cov molybdenum (MO ~ 2. 0-2.5%) cov ntsiab lus. Nws ua tau zoo dua hauv cov tub rog marine, dej qab ntsev, thiab kev txhoj puab ib puag ncig.
1 . 4541/321 ss round yeeb muaj nyob rau hauv ib puag ncig corrosion, tab sis tsis muaj molybdenum, ua rau nws tsim nyog rau chloride-nplua nuj.
2. Kev ua haujlwm kub siab
1 . 4541 stainless seamless yeeb yog titanium-stabilation, uas tiv thaiv kev ua kom zoo nkauj. nws yog qhov zoo tagnrho rau kev ua haujlwm tas mus li 850 degree.
1 {. 4404 stainless seamless cov yeeb nkab tuaj yeem tiv thaiv kev sib tw sib kis tau txog 870℃tej zaum yuav ua rau muaj kev xav thiab xeb.
3. Hwj txwv
Ob qib yog weldable siv cov qauv txheem (tig / Mig), tab sis:
1 {.} 4541 ss tuab phab ntsa pipedoes tsis xav tau tom qab weld kev kho cua sov vim Ti stabilization.
1 . 4404 ss tuab phab ntsa yeeb nkab yeeb yaj kiab, tab sis yuav tsum tau saib xyuas ntau dua thaum siv cov xeb tuab lossis cov huab cua siab.
Uas kim dua: 321 lossis 316L stainless yeeb nkab?
In general, 316L stainless steel pipe is more expensive than 321 stainless steel pipe, primarily due to its higher molybdenum content, which enhances corrosion resistance-especially in chloride-rich environments.
Puas yog 1.4541 stainless hlau siv rau kev sib pauv cua sov?
| Daim Ntawv Thov Hom | 1.4541 (321) | 1.4404 (316L) |
|---|---|---|
| Tub Rog Tshav Kub Kub | ✅ Cov tau zoo heev | ⚠ Txwv yog tias saum 450 degree |
| Kev Siv Hluav Taws Xob (Tsis Yog Chloride) | ✅ Zoo | ✅ Cov tau zoo heev |
| Dej hiav txwv / marine piping | ❌ TSIS pom zoo | ✅ Zoo tagnrho |
| Welded Rauv Cheebtsam | ✅ Cov tau zoo heev | Kev pheej hmoo ntawm cov rhiab |
| Khoom Noj & Haus Piping | Siv tau | Nyiam (kev tu huv si, corrosion) |
