I-AISI 904L intsimbi engagqwaliyo okanye i-AISI 904L (WNR1.4539) I-ASTM A 249, N08904, X1NiCrMoCu25-20-5 yintsimbi engagqwaliyo ene-alloy ephezulu. Xa ithelekiswa ne-316L, i-SS904L inomxholo ophantsi wekhabhoni (C), umxholo ophezulu we-chromium (Cr), kwaye malunga nomxholo ophindwe kabini we-nickel (Ni) kunye ne-molybdenum (Mo) we-316L, nto leyo enika ubushushu obuphezulu...
I-904L (N08904,, 14539) intsimbi engagqwali ye-super austenitic ine-19.0-21.0% ye-chromium, i-24.0-26.0% ye-nickel, kunye ne-4.5% ye-molybdenum. I-904L intsimbi engagqwali ye-super austenitic yintsimbi engagqwali ye-carbon ephantsi, i-nickel ephezulu, i-molybdenum enganyangekiyo yi-molybdenum, eyimpahla eyimpahla evezwe yinkampani yaseFransi i-H·S. Inamandla okuguqula i-activation-passivation, ukumelana okuhle kokugqwala, ukumelana okuhle kokugqwala kwii-asidi ezingezizo i-oxidizing ezifana ne-sulfuric acid, i-acetic acid, i-formic acid, i-phosphoric acid, ukumelana okuhle kokugqwala kwi-ion ye-chloride engathathi hlangothi, kunye nokuxhathisa okuhle kokugqwala kunye nokugqwala koxinzelelo. Ifanelekile kwiindidi ezahlukeneyo ze-sulfuric acid ngaphantsi kwama-70°C, kwaye inokumelana okuhle kokugqwala kwi-acetic acid yayo nayiphi na i-concentration kunye nayo nayiphi na iqondo lobushushu phantsi koxinzelelo oluqhelekileyo, kunye ne-acid exutyiweyo ye-formic acid kunye ne-acetic acid.
Intsimbi engagqwaliyo ye-AISI 904L yintsimbi engagqwaliyo ye-austenitic ene-alloy ephezulu enomxholo ophantsi kakhulu wekhabhoni. Ukudibanisa i-chromium ephezulu, i-nickel, i-molybdenum kunye ne-copper kunika intsimbi ukumelana nokugqwala okufanayo. Ukongezwa kwe-copper kuyenza ibe nokumelana okunamandla kwe-asidi, inokumelana nee-asidi ezahlukeneyo ze-organic kunye ne-inorganic, ingakumbi i-chloride crevice corrosion kunye ne-stress corrosion cracking, akulula ukuba namabala okugqwala kunye nee-cracks, kwaye inokumelana okunamandla kwe-pitting. I-AISI 904L inokumelana okuhle kokugqwala kwi-dilute sulfuric acid. I-alloy yintsimbi efanelekileyo kwi-dilute sulfuric acid enamandla e-corrosive medium. Ikwamelana namanzi olwandle, inokusebenza kakuhle kunye nokudityaniswa, kwaye isetyenziswa kakhulu kumashishini okwakha, amachiza, ezonyango nakwamanye amashishini.
Intsimbi engagqwaliyo ye-AISI 904L isetyenziswa kakhulu kwii-reactors kwizixhobo zepetroleum kunye ne-petrochemical; izixhobo zokugcina kunye nezokuthutha i-sulfuric acid, ezifana nezitshintshi zobushushu; izixhobo zokususa i-flue gas desulfurization kwizityalo zamandla, ezifana neetower, iiflue, ii-shutters, izinto zangaphakathi, ii-sprayers, iifeni, njl. kwiinkqubo zonyango lwe-organic acid; izixhobo zonyango lwamanzi olwandle, ezifana nezitshintshi zobushushu bamanzi olwandle; izixhobo zoshishino lwephepha, i-sulfuric acid, izixhobo ze-nitric acid; izixhobo zeekhemikhali, izitya zoxinzelelo, izixhobo zokutya ezifana nokwenza i-asidi kunye namashishini amayeza.
