904L (N08904,, 14539) sili austenitic uʻamea uamea e aofia ai 19.0-21.0% chromium, 24.0-26.0% nickel, ma 4.5% molybdenum. 904L super austenitic uʻamea uʻamea o se kaponi maualalo, nickel maualuga, molybdenum austenitic uʻamea uʻamea-tetee uamea, o se mea faʻapitoa faʻalauiloa mai le kamupani Farani H·S. O loʻo i ai le malosi o le suiga o le faʻagaioiga-passivation, lelei le faʻafefeteina o le corrosion, le lelei o le corrosion resistance i non-oxidizing acids e pei o le sulfuric acid, acetic acid, formic acid, phosphoric acid, lelei le faʻafefeteina o le chloride ion media, ma le faʻamaʻi lelei o le gaogao ma le faʻalavelave faʻalavelave. E talafeagai mo concentrations eseese o le sulfuric acid i lalo ifo o le 70 ° C, ma e lelei le corrosion teteʻe i le acetic acid o soʻo se faʻatonuga ma soʻo se vevela i lalo o le mamafa masani, ma fefiloi acid o formic acid ma acetic acid.
AISI 904L u'amea u'amea o se u'amea maualuga austenitic u'amea ma matua maualalo anotusi carbon. O le tuufaatasiga o le chromium maualuga, nickel, molybdenum ma le kopa e maua ai le uamea lelei toniga tetee corrosion. O le fa'aopoopoina o le kopa e maua ai le malosi o le fa'asa'o, e mafai ona tete'e atu i vaila'au fa'ala'au ma inorganic eseese, ae maise le chloride crevice corrosion ma le fa'alavelave fa'afefe, e le faigofie ona i ai ni mea e pala ma ta'e, ma e malosi le fa'asagaga. AISI 904L o loʻo i ai le faʻafefeteina lelei i le faʻafefeteina o le sulfuric acid. O le u'amea o se u'amea talafeagai mo le dilute sulfuric acid malosi corrosive medium. E tetee foi i le sami, e lelei machinability ma weldability, ma e lautele faaaogaina i le fausiaina, vailaau, faafomai ma isi alamanuia.
AISI 904L u'amea u'amea e masani ona fa'aaogaina i reactors i le suau'u ma masini petrochemical; sulfuric acid teuina ma felauaiga meafaigaluega, e pei o le vevela; fa'amu gas desulfurization meafaigaluega i totonu o le eletise, e pei o olo, paipa, tapuni, vaega i totonu, sprayers, ili, ma isi i faiga faʻalaʻau vailaʻau togafitiga; meafaigaluega e fa'amama ai le suasami, e pei o mea fa'asuavai suasami; meafaigaluega alamanuia pepa, sulfuric acid, nitric acid meafaigaluega; mea tau vaila'au, va'a mamafa, mea'ai mea'ai e pei o le gaosiga o vaila'au ma falema'i.
