Insimbi Engagqwali 904 / 904L
Amagama Okuhweba Ajwayelekile: Ingxubevange 904L ,N08904 , W.Nr1.4539 ,I-N08904 ,I-Cr20Ni25Mo4.5Cu
I-904L iyi-Super Austenstic Stainless Steel ngokuqukethwe kwekhabhoni ephansi.Ibanga lihloselwe ukusetshenziswa ngaphansi kwezimo ezinzima zokugqwala.Kuye kwafakazelwa ukusetshenziswa eminyakeni eminingi futhi yasungulwa ekuqaleni ukuze imelane nokugqwala ku-dilute sulfuric acid.Ilinganiswe futhi ivunyelwe ukusetshenziswa kwemikhumbi yokucindezela emazweni amaningana.Ngokwesakhiwo, i-904L i-austenitic ngokugcwele futhi ayizweli kancane ezigabeni zemvula ze-ferrite ne-sigma kunamamaki avamile e-austenitic anokuqukethwe okuphezulu kwe-molybdenum.Ngokwesimo, ngenxa yokuhlanganiswa kokuqukethwe okuphezulu kwe-chromium, i-nickel, i-molybdenum nethusi i-904L inokumelana okuhle nokugqwala okuvamile, ikakhulukazi ezimweni zesulfuric ne-phosphoric.

Izinto ze-alloy 904L ezinhlotsheni zama-Bolts, izikulufu, ama-flanges nezinye izinto ezisheshayo, ngokuya ngokucaciswa kwamakhasimende.
Kungani i-Alloy 904L?
•Ukumelana kahle nokugqwala kwemigodi nokugqwala kwemifantu
•Ukumelana okuphezulu nokuqhekeka kokugqwala kwengcindezi, i-intergranular, i-machinability enhle kanye nokushisela
•Kuzo zonke izinhlobo ezihlukahlukene ze-phosphates904L ingxubevange ukumelana nokugqwala kuphakeme kunensimbi engagqwali evamile.
•Ku-oxidizing nitric acid eqinile, uma kuqhathaniswa ne-alloy ephezulu ngaphandle kwebanga lensimbi ye-molybdenum, i-904L ibonisa ukumelana nokugqwala okuphansi.
•Le alloy inokumelana nokugqwala okungcono kunensimbi engagqwali evamile.
•Yehlisa izinga lokugqwala komgodi kanye nezikhala zokuqukethwe okuphezulu kwe-nickel, futhi ube nokumelana kahle nokugqwala kwengcindezi.ukuqhekeka, endaweni yesisombululo se-chloride, ukugcwala kwesisombululo se-hydroxide kanye ne-hydrogen sulphide ecebile.
I-alloy 904L Inkambu yohlelo lokusebenza:
•Imishini ye-petroleum ne-petrochemical, njenge-reactor yemishini ye-petrochemical, njll.
•Isitoreji se-sulfuric acid kanye nezinto zokuhamba, ezifana nezishintshisi zokushisa, njll.
•I-power plant flue gas desulfurization devicen,Izingxenye Eziyinhloko zokusetshenziswa:umzimba we-absorber tower, flue, izingxenye zangaphakathi, uhlelo lwesifutho, njll.
•I-Organic acid scrubber kanye nefeni kusistimu yokucubungula.
•Isikhungo sokuhlanza amanzi, isishintshi sokushisa kwamanzi, izinto zokwakha amaphepha, i-sulfuric acid, imishini ye-nitric acid, i-asidi,
•Imboni yemithi kanye nezinye izinto zamakhemikhali, isitsha sokucindezela, imishini yokudla.
•Ezemithi: i-centrifuge, i-reactor, njll.
•Ukudla kwezitshalo: ibhodwe lesoso yesosi, iwayini lokupheka, usawoti, izinto zokusebenza kanye nezingubo zokugqoka.
•Ukuncibilikisa i-sulfuric acid insimbi egqwalayo emaphakathi engu-904 l iyahambelana.
