904L ipleyiti yensimbi engenasiciluhlobo lwe-austenitic stainless steel kunye nomxholo wekhabhoni ophantsi kakhulu kunye ne-alloying ephezulu eyenzelwe iindawo ezineemeko ezinobungozi ezinobungozi.Inokumelana ne-corrosion engcono kune316Lkwaye317L, ngelixa kuthathelwa ingqalelo ixabiso, ukusebenza, kunye neendleko ezifanelekileyo.phezulu.Ngenxa yokongezwa kwe-1.5% yobhedu, inokumelana ne-corrosion egqwesileyo ekunciphiseni i-acids efana ne-sulfuric acid kunye ne-phosphoric acid.Ikwanayo nokumelana ne-corrosion egqwesileyo ngokuchasene ne-corrosion pitting kunye ne-crevice corrosion ebangelwa ii-ion ze-chloride, kwaye inokumelana kakuhle ne-intergranular corrosion.Kwi-asidi ye-sulfuric ecocekileyo kwi-concentration range ye-0-98%, ubushushu benkonzo ye-904L yeplate yensimbi bunokufikelela kuma-40 degrees Celsius.Kwi-asidi ye-phosphoric ecocekileyo kwi-concentration range ye-0-85%, ukuxhathisa kwayo kwe-corrosion kuhle kakhulu.Kwimizi-mveliso ye-phosphoric acid eveliswa ziinkqubo ezimanzi, ukungcola kunempembelelo enamandla ekuxhathiseni ukubola.Phakathi kwazo zonke iintlobo ze-asidi ye-phosphoric, i-904L i-super austenitic steel stainless inokumelana nokukhula okungcono kunentsimbi eqhelekileyo engenasici.Kwi-asidi eyomeleleyo ye-oxidizing, i-904L yensimbi engenasici inoxhathiso olusezantsi lokutya kuneentlobo ezahlukeneyo zentsimbi edibeneyo.phakathi kolu luhlu loxinaniso.Ukuxhatshazwa kwe-corrosion ye-904L yensimbi ingcono kuneyesiqhelo yensimbi engenasici.I-904L yensimbi engenasici inokumelana okuphezulu kwi-corrosion.Ukuxhathisa kwayo kwi-corrosion ye-crevice kwizisombululo ze-chloride.Amandla nawo mahle kakhulu.Umxholo we-nickel ophezulu we904L ipleyiti yentsimbikunciphisa izinga lokubola kwimingxuma kunye nemithungo.Ngenxa yomxholo wayo ophezulu we-nickel, i-904L inokumelana okuphezulu noxinzelelo lwe-corrosion cracking kwizisombululo ze-nitride, i-concentrated hydroxide solutions kunye ne-hydrogen sulfide-rich environments.
