Qhov txawv: AISI 904L VS 316L yog dab tsi?
Muaj qhov sib txawv tseem ceeb ntawm 904l stainless hlau thiab 316l stainless hlau nyob rau hauv cov nqe lus ntawm muaj pes tsawg leeg thiab lub cev muaj zog xws li corrosion kuj thiab kub kuj. 904L stainless hlau yog tsim los ntawm hlau, chromium, npib tsib xee, molybdenum, tooj liab, nitrogen thiab manganese, thaum 316L stainless hlau yog tsim los ntawm hlau, chromium, nickel thiab molybdenum. Hais txog tus nqi, 904L kim dua 316L vim nws cov ntsiab lus ntau dua nickel thiab molybdenum.

1. Kev Sau thiab Nqi:
904L Stainless hlau:
Xws li hlau, chromium, nickel, molybdenum, tooj liab, nitrogen, thiab manganese.
Cov qib siab ntawm nickel thiab molybdenum ua rau muaj kev tiv thaiv corrosion zoo dua.
Ntau tshaj li 316L vim nws cov ntsiab lus siab alloy.
316L Stainless hlau:
Xws li hlau, chromium, nickel, thiab molybdenum.
Tsawg alloy cov ntsiab lus ua rau cov khoom siv nyiaj ntau dua.
2. Corrosion Resistance:
N08904 Stainless hlau:
Exceptional tiv thaiv corrosion, kev nyuaj siab-corrosion tawg, thiab pitting.
Qhov zoo tshaj plaws rau cov ntawv thov kev ntxhov siab xws li cov khoom siv tshuaj lom neeg.
S31603 Stainless hlau:
Muaj kev tiv thaiv corrosion zoo tab sis tsis zoo li 904L.
Feem ntau siv nyob rau hauv ib puag ncig tsis nruj xws li cov khoom siv ua zaub mov thiab chaw marine.
3. Weldability:
EN 1.4539 Stainless hlau:
Tsawg weldable piv rau 316L.
Cov qib siab ntawm chromium, npib tsib xee, thiab molybdenum tuaj yeem tsim teeb meem hauv kev vuam yam tsis ua rau kub tawg.
DIN 1.4404 / 1.4435 Stainless hlau:
Paub txog qhov zoo weldability, ua rau nws nyiam xaiv rau ntau yam kev siv vuam.
4. Temperature Tolerance:
AISI 904L Stainless hlau:
Kev kub siab ua haujlwm siab tshaj 316L.
Haum rau cov ntawv thov nyob rau hauv qhov chaw kub kub, xws li roj refineries thiab nuclear fais fab nroj tsuag.
AISI 316L Stainless hlau:
Tsawg kub kam rau ua piv rau 904L.
5. Kev Siv Lag Luam thiab Kev Siv Khoom Siv:
904L Stainless hlau:
Txawm hais tias cov khoom zoo tshaj plaws, tsis tshua siv ntau dua 316L.
Ntau dua nyob rau hauv daim ntawv thov uas yuav tsum tau siab corrosion kuj, xws li tshuaj ua.
316L Stainless hlau:
Dav siv vim zoo weldability thiab nqi-effectiveness.
Cov ntawv thov feem ntau suav nrog cov khoom siv ua zaub mov, cov khoom siv tshuaj lom neeg, thiab thaj chaw hauv hiav txwv.
6. Kev txiav txim siab nqi:
Tus nqi sib txawv ntawm 904L thiab 316L tuaj yeem sib txawv raws li kev ua lag luam.
Cov khoom zoo tshaj ntawm 904L tuaj yeem ua pov thawj nws tus nqi siab dua hauv cov ntawv thov uas muaj kev tiv thaiv corrosion tseem ceeb.
7. Magnetic Properties:
Ob leegss904l316l uayog cov tsis sib nqus austenitic stainless hlau.
Haum rau cov ntawv thov uas tsis xav tau cov khoom sib nqus.
Hauv kev xaus, qhov kev xaiv ntawmAISI 904L thiab 316L stainless hlaunyob ntawm cov ntawv thov tshwj xeeb, nrog rau 904L ua tau zoo hauv cov cheeb tsam corrosive thiab cov ntawv thov kev ntxhov siab, thaum 316L muab cov kev daws teeb meem zoo dua nrog cov weldability zoo hauv cov kev xav tau tsawg.
