Insimbi engenaStainless 904 / 904L
Amagama oRhwebo oluQhelekileyo: Ingxubevange 904L ,N08904 , W.Nr1.4539 ,N08904 ,Cr20Ni25Mo4.5Cu
I-904L yiNtsimbi yeAustenstic eStainless kunye nomxholo wekhabhoni ephantsi.Ibakala lenzelwe ukusetyenziswa phantsi kweemeko ezimandundu ezonakalisayo.Kuye kwangqinwa ukusetyenziswa kwiminyaka emininzi kwaye yaphuhliswa ekuqaleni ukuxhathisa ukubola kwi-dilute sulfuric acid.Ibekwe emgangathweni kwaye ivunyiwe ukuba isetyenziswe kwinqanawa yoxinzelelo kumazwe aliqela.Ngokwesakhiwo, i-904L i-austenitic ngokupheleleyo kwaye ayinamvakalelo encinci kwi-precipitation ferrite kunye nezigaba ze-sigma kunamabakala aqhelekileyo e-austenitic anomxholo ophezulu we-molybdenum.Ngokwempawu, ngenxa yokudityaniswa kwezinto eziphezulu ze-chromium, i-nickel, i-molybdenum kunye ne-904L yobhedu inokuxhathisa okulungileyo kwi-corrosion jikelele, ngakumbi kwiimeko zesulfuric kunye ne-phosphoric.

Kutheni iAlloy 904L ?
•Ukuxhathisa okulungileyo ekufakeni umhlwa kunye nokuhlwa kwemingxuma
•Ukuchasana okuphezulu kuxinzelelo lwe-corrosion cracking, i-intergranular, i-machinability elungileyo kunye ne-weldability
•Kuzo zonke iintlobo ezahlukeneyo ze-phosphates904L i-alloy corrosion resistance iphezulu kunentsimbi eqhelekileyo engenasici.
•Kwi-asidi ye-nitric oxidizing eyomeleleyo, xa kuthelekiswa ne-alloy ephezulu ngaphandle kwebakala lensimbi ye-molybdenum, i-904L ibonisa ukuxhathisa okuphantsi kokuhlwa.
•Le ngxubevange inokumelana ne-corrosion engcono kunentsimbi eqhelekileyo yentsimbi.
•Ukunciphisa izinga lokubola komngxuma kunye nezithuba zomxholo ophezulu we-nickel, kwaye ube nokumelana kakuhle noxinzelelo lwe-corrosion.ukuqhekeka, kwindawo yesisombululo sekloridi, ukuxinwa kwesisombululo se-hydroxide kunye ne-hydrogen sulphide ecebileyo.
I-alloy 904L indawo yesicelo:
•Ipetroleum kunye nezixhobo zepetrochemical, ezifana ne-reactor yezixhobo zepetrochemical, njl.
•Ukugcinwa kwe-asidi ye-sulfuric kunye nezixhobo zokuthutha, ezifana nabatshintshi bokushisa, njl.
•Isixhobo samandla segesi ye-flue desulfurization devicen, iindawo eziphambili zokusetyenziswa: i-absorbetor tower body, flue, amalungu angaphakathi, inkqubo yokutshiza, njl.
•Organic acid scrubber kunye fan kwinkqubo processing.
•Iplanti yokucoca amanzi, isitshintshi sobushushu bamanzi, izixhobo zokwenza iphepha, iasidi yesulfuric, izixhobo ze-nitric acid, iasidi,
•Ishishini lamachiza kunye nezinye izixhobo zekhemikhali, inqanawa yoxinzelelo, izixhobo zokutya.
•I-Pharmaceutical: i-centrifuge, i-reactor, njl.
•Ukutya kwezityalo: imbiza yesosi yesosi, iwayini yokupheka, ityuwa, izixhobo kunye nezinxibo.
•Ukungxengxeza iasidi yesulfuric eyomeleleyo yentsimbi ekruqulayo ephakathi 904 l iyahambelana.
