I-904L i-austenitic stainless steel yeye-carbon ephantsi, i-nickel ephezulu, i-molybdenum austenitic insimbi engenasici kunye nokumelana ne-asidi.I-904L i-austenitic stainless steel inamandla okuguqula i-activation passivation, ukuxhathisa okugqwesileyo, ukuchasana kakuhle kwe-corrosion kwi-non-oxidizing acids ezifana ne-asidi ye-sulfuric, i-acetic acid, i-asidi ye-fomic, kunye ne-asidi ye-phosphoric, ukuxhathisa kakuhle kwi-corrosion kwimidiya ye-ion ye-chloride engathathi hlangothi, kwaye ilungile. ukuxhathisa kwi-corrosion kunye noxinzelelo lwe-corrosion.Ifanele imilinganiselo eyahlukeneyo ye-asidi ye-sulfuric engaphantsi kwe-70 ℃, inokumelana nokuhlwa okulungileyo kuyo nayiphi na ingxinano kunye nobushushu be-acetic acid kunye nomxube we-asidi ye-acetic kunye ne-acetic acid phantsi koxinzelelo oluqhelekileyo.

I-Austenitic stainless steel 904L yintsimbi ephezulu ye-alloy austenitic ene-carbon content.Inokumelana ne-corrosion elungileyo kwi-dilute sulfuric acid kwaye yenzelwe indawo ezineemeko ezirhabaxa zomhlwa.Inomxholo wechromium ophezulu kunye nomxholo we-nickel owaneleyo.Ukongezwa kobhedu kunika ukuxhathisa okuqinileyo kweasidi, ngakumbi ukuxhathisa okuphezulu kwi-chloride interstitial corrosion kunye noxinzelelo lwe-corrosion cracking.Ayinabungozi kangako kwiindawo zokubola kunye nokuqhekeka, kwaye ukuchasana kwayo ne-corrosion ye-pitting kungcono kancinci kunamanye amabakala entsimbi.Inokusebenza kakuhle kunye ne-weldability kwaye ingasetyenziselwa kwiinqanawa zoxinzelelo.

I-904L ngumxholo wekhabhoni ephantsi, i-alloying ephezulu ye-austenitic stainless steel eyenzelwe iindawo ezinobungozi ezinobungozi.Inokumelana ne-corrosion engcono kune-316L kunye ne-317L, ngelixa ilinganisa ixabiso kunye nokusebenza, kwaye ineendleko eziphezulu zokusebenza.Ngenxa yokongezwa kwe-1.5% yobhedu, inokumelana ne-corrosion egqwesileyo yokunciphisa ii-asidi ezifana ne-sulfuric acid kunye ne-phosphoric acid.Ikwanayo nokumelana ne-corrosion egqwesileyo kuxinzelelo lwe-corrosion, i-pitting corrosion, kunye ne-crevice corrosion ebangelwa yi-chloride ion, kwaye inokumelana kakuhle ne-intergranular corrosion.Kwi-asidi ye-sulfuric ecocekileyo kunye noluhlu lwe-concentration ye-0-98%, ubushushu bokusetyenziswa kwe-904L bunokufikelela kuma-40 degrees Celsius.Kwi-asidi ye-phosphoric ecocekileyo kunye noluhlu lwe-concentration ye-0-85%, ukuxhathisa kwayo kwe-corrosion kuhle kakhulu.Ukungcola kunempembelelo enamandla kwi-corrosion resistance ye-industrial phosphoric acid eveliswa yiteknoloji yenkqubo emanzi.Phakathi kwazo zonke iintlobo ze-asidi ye-phosphoric, i-904L inokumelana ne-corrosion engcono kunentsimbi eqhelekileyo engenasici.Kwi-asidi ye-nitric ene-oxidizing kakhulu, i-904L inokumelana ne-corrosion ephantsi xa kuthelekiswa namabakala aphezulu ensimbi ene-alloyed ngaphandle kwe-molybdenum.Kwi-hydrochloric acid, ukusetyenziswa kwe-904L kunqunyelwe kwiindawo ezisezantsi ze-1-2%.Ngaphakathi kolu luhlu loxinaniso.Ukuxhatshazwa kwe-corrosion ye-904L kungcono kuneyentsimbi yesiqhelo.I-904L yentsimbi inokuxhathisa okuphezulu kwi-corrosion.Ukuxhathisa kwayo kwi-corrosion ye-crevice kwisisombululo se-chloride.Amandla nawo mahle kakhulu.Umxholo we-nickel ophezulu we-904L unciphisa izinga lokubola kwimibhobho kunye nemigodi.Ordinary austenitic stainless steel inokuba novakalelo kuxinzelelo lwecorrosion kwindawo etyebileyo kwikloridi kumaqondo obushushu angaphezu kwama-60 degrees celcius.Ngokunyusa umxholo we-nickel wensimbi engenasici, le mvakalelo inokuncitshiswa.Ngenxa yomxholo wayo ophezulu we-nickel, i-904L ibonisa ukuchasana okuphezulu koxinzelelo lwe-corrosion cracking kwizisombululo ze-chloride, izisombululo ze-hydroxide ezigxininisiweyo, kunye neendawo ezizityebi kwi-hydrogen sulfide.

I-petroleum kunye nezixhobo zepetrochemical, ezifana nezixhobo ze-petrochemical, ukugcinwa kunye nezixhobo zokuthutha ze-sulfuric acid, ezifana nokutshintshiselana kobushushu, izixhobo ze-flue flue gas desulfurization, ezisetyenziswa kakhulu kumzimba wenqaba, i-flue, iipaneli zomnyango, izinto zangaphakathi, iinkqubo zokutshiza, njl , iifektri zamayeza: i-centrifuges, i-reactors, njl., ukutya kwesityalo: iitanki zesosi yesosi, iwayini yokupheka, iitanki zetyuwa, izixhobo kunye nokunxiba, i-904L linqanaba lentsimbi elihambelanayo le-dilute sulfuric acid esomeleleyo esonakalisa isiphakathi.

Ipleyiti, umcu, ibha, ucingo, ukubumba, intonga egudileyo, izinto zokuwelda, iflange, njl.njl., inokuqhutywa ngokomzobo
