904L|N08904 Pa'u Uamea
Fa'amatalaga Puupuu:
904L austenitic uʻamea uʻamea e patino i le kaponi maualalo, nickel maualuga, molybdenum austenitic uʻamea uʻamea ma acid tetee.904L austenitic uʻamea uʻamea e sili ona lelei le faʻagaoioia o suiga o le passivation, sili ona lelei teteʻeina o le corrosion, lelei le corrosion resistance i non oxidizing acids e pei o le sulfuric acid, acetic acid, formic acid, ma le phosphoric acid, lelei teteʻe i pitting corrosion i le neutral chloride ion media, ma lelei. tete'e i le ga'o ma'a ma fa'amamafa.E fetaui lelei mo faʻasalalauga eseese o le sulfuric acid i lalo ifo o le 70 ℃, e lelei le faʻafefeteina o soʻo se faʻamalositino ma le vevela o le acetic acid ma le faʻafefiloi o le formic acid ma le acetic acid i lalo o le mamafa masani.
904L ose mea maualalo kaponi, maualuga alloying austenitic uʻamea uʻamea fuafuaina mo siosiomaga corrosive malosi.E sili atu le tete'e o le corrosion nai lo le 316L ma le 317L, a'o paleni le tau ma le fa'atinoga, ma e maualuga atu le tau-lelei.Ona o le faʻaopoopoga o le 1.5% kopa, e sili ona lelei le faʻafefeteina mo le faʻaitiitia o vailaʻau e pei ole sulfuric acid ma le phosphoric acid.O lo'o i ai fo'i le lelei tele o le fa'afefeteina i le fa'amamafaina o le fa'amamafa, pitting corrosion, ma le ga'o fa'apogai e mafua mai i ion chloride, ma e lelei le tete'e atu i intergranular corrosion.I totonu o le sulfuric acid mama ma le faʻaogaina o le 0-98%, o le faʻaaogaina o le vevela o le 904L e mafai ona oʻo atu i le 40 tikeri Celsius.I totonu o le phosphoric acid mama ma le faʻaogaina o le 0-85%, o lona teteʻe o le pala e lelei tele.O mea leaga e iai se a'afiaga malosi i le fa'afefeteina o le phosphoric acid fale gaosi oloa e gaosia e tekinolosi faiga susu.Faatasi ai ma ituaiga uma o le phosphoric acid, 904L e sili atu le faʻafefeteina nai lo le uʻamea masani.I le maualuga o le oxidizing nitric acid, 904L o loʻo i ai le faʻaitiitia o le faʻafefeteina pe a faʻatusatusa i togi uʻamea maualuga e aunoa ma le molybdenum.I le hydrochloric acid, o le faʻaaogaina o le 904L e faʻatapulaʻa i faʻamaulalo maualalo o le 1-2%.I totonu o lenei vaega fa'atonuga.E sili atu le malosi o le corrosion o le 904L nai lo le u'amea masani.904L u'amea e maualuga le tetee i pitting corrosion.O lona tete'e atu i le gaogao i le vaifofo chloride.E lelei tele foi le malosi.O le maualuga o le nickel content o le 904L e faʻaitiitia ai le pala i lua ma va.O le u'amea austenitic masani e ono ma'ale'ale i le fa'amamafaina o le pala i totonu o se si'osi'omaga mauoa i le chloride i le vevela i luga atu o le 60 tikeri Celsius.E ala i le faʻateleina o le nickel content of the stainless steel, e mafai ona faʻaitiitia lenei lagona.Ona o le maualuga o le nickel content, o le 904L o loʻo faʻaalia ai le maualuga o le teteʻe i le faʻamaʻiina o le pala i vaifofo chloride, vaifofo faʻamaʻi hydroxide, ma siosiomaga mauoa i le hydrogen sulfide.
Suauʻu ma petrochemical meafaigaluega, e pei o reactors i petrochemical meafaigaluega, teuina ma felauaiga mea mo le sulfuric acid, e pei o le vevela exchangers, afi afi afi kesi desulfurization masini, e masani ona faʻaaogaina i le tino olo, fulu, panels faitotoa, vaega totonu, faiga spray, ma isi o olo absorption, scrubbers ma ili i faiga oona oona togafitiga, suasami togafitiga masini, suavai suauʻu vevela, pepa meafaigaluega alamanuia, sulfuric acid ma nitric mea meafaigaluega, gaosiga o le acid, ma isi alamanuia Pharmaceutical ma isi meafaigaluega kemisi, ipu mamafa, meafaigaluega meaai. , fale talavai: centrifuges, reactors, ma isi, meaʻai toto: soya sosi tane, kuka uaina, tane masima, meafaigaluega ma dressings, 904L o se vasega uamea tutusa mo dilute sulfuric acid malosi corrosive medium.
Papatusi, fasi, pa, uaea, forging, tootoo lamolemole, mea uʻamea, flange, ma isi, e mafai ona faʻagasolo e tusa ai ma le ata tusi.
