Uamea uamea 904 / 904L
Igoa Fefa'ataua'iga masani: Alloy 904L,N08904 , W.Nr1.4539 ,N08904 ,Cr20Ni25Mo4.5Cu
904L o le Super Austenstic Stainless Steel fa'atasi ai ma le maualalo o le kaponi.O le togi e fa'amoemoe mo le fa'aogaina i lalo o tulaga fa'aleagaina.Ua fa'amaonia le fa'aogaina i le tele o tausaga ma sa fa'atupuina muamua e tete'e ai le pala ile fa'a'ele'ele sulfuric acid.Ua fa'ata'atia ma fa'amaonia mo le fa'aogaina o va'a mamafa i le tele o atunu'u.I le fa'atulagaina, 904L e matua'i austenitic ma e itiiti le ma'ale'ale i timuga ferrite ma sigma vaega nai lo togi austenitic masani ma maualuga molybdenum anotusi.Fa'ailoga, ona o le tu'ufa'atasiga o mea e sili ona maualuga o le chromium, nickel, molybdenum ma le copper 904L e lelei le tete'e atu i le pala, aemaise lava i tulaga sulfuric ma phosphoric.

Aisea Alloy 904L?
•Lelei le tetee atu i le pala ma le gaogao
•Maualuluga tete'e i fa'amamafa corrosion ta'e, intergranular, machinability lelei ma weldability
•I ituaiga eseese uma o le phosphates904L alloy corrosion resistance e sili atu nai lo le sila stainless masani.
•I le malosi oxidizing nitric acid, faʻatusatusa i le uʻamea maualuga e aunoa ma le molybdenum vasega uamea, 904L faʻaalia le faʻafefeteina maualalo.
•O lenei u'amea e sili atu le tete'e i le corrosion nai lo le uamea u'amea masani.
•Faʻaitiitia le fua o le aʻa o le lua ma va mo le maualuga o mea o loʻo i totonu o le nickel, ma ia lelei le teteʻe atu i faʻamaʻi faʻafefe.ta'e, i le si'osi'omaga o le vaifofo chloride, fa'atonuga o vaifofo hydroxide ma mauoa hydrogen sulphide.
Alloy 904L Talosaga fanua:
•Suauʻu ma masini suauʻu, e pei o le reactor o meafaigaluega suauu, ma isi.
•Sulfuric acid teuina ma felauaiga meafaigaluega, e pei o le vevela, ma isi.
•Malosiaga afi kasa desulfurization devicen, Vaega autu o le faaaogaina: o le tino o le olo absorber, fa'agogo, vaega totonu, spray system, ma isi.
•Fa'amama fa'aola fa'aola ma le ili i le faiga fa'agaioiga.
•Fale fa'asusu vai, su'e vevela vai, mea e fai ai pepa, sulfuric acid, nitric acid mea faigaluega, acid,
•Alamanuia vaila'au ma isi mea kemisi, va'a mamafa, mea'ai mea'ai.
•Pharmaceutical: centrifuge, reactor, ma isi.
•Mea'ai toto: ulo soya, uaina kuka, masima, meafaigaluega ma laei.
•E fa'afefete ai le sulfuric acid malosi fa'a'a'ala'au u'amea 904 l e fetaui.
