Simbi isina ngura yeAISI 904L kana kuti AISI 904L (WNR1.4539) ASTM A 249, N08904, X1NiCrMoCu25-20-5 isimbi isina ngura ine alloy yakawanda. Kana ichienzaniswa ne316L, SS904L ine kabhoni (C) shoma, chromium (Cr) yakawanda, uye inenge kaviri nickel (Ni) nemolybdenum (Mo) zviri mukati me316L, zvichipa tembiricha yakakwira...
904L (N08904,, 14539) simbi isina tsvina ine 19.0-21.0% chromium, 24.0-26.0% nickel, uye 4.5% molybdenum. 904L simbi isina tsvina ine carbon shoma, nickel yakawanda, molybdenum austenitic stainless acid-resistant, inova chinhu chakaunzwa kubva kukambani yeFrance H·S. Ine kugona kwakanaka kwekushandura activation-passivation, inodzivirira ngura zvakanaka, inodzivirira ngura zvakanaka mu non-oxidizing acids dzakadai se sulfuric acid, acetic acid, formic acid, phosphoric acid, inodzivirira gomba zvakanaka mu neutral chloride ion media, uye inodzivirira ngura zvakanaka mu crevice uye stress corrosion. Yakakodzera kuwanda kwakasiyana kwe sulfuric acid pasi pe 70°C, uye inodzivirira ngura zvakanaka mu acetic acid yechero concentration uye chero tembiricha iri pasi pekumanikidzwa kwakajairika, uye musanganiswa we formic acid ne acetic acid.
Simbi isina ngura yeAISI 904L isimbi isina ngura ine alloy yakawanda ine kabhoni shoma. Kusanganiswa kwechromium yakawanda, nickel, molybdenum nemhangura kunoita kuti simbi irambe yakasimba mukuora. Kuwedzerwa kwemhangura kunoita kuti ive nesimba rekukunda acid, inogona kuramba akasiyana-siyana organic ne inorganic acids, kunyanya chloride crevice corrosion uye stress corrosion cracking, hazvisi nyore kuva nemavanga ekuora uye kutsemuka, uye ine simba rekukunda makomba. AISI 904L ine simba rekukunda corrosion mu dilute sulfuric acid. Alloy iyi isimbi yakakodzera dilute sulfuric acid ine simba rekuora. Inodzivirirawo mvura yegungwa, ine simba rekuchinjika uye kusveta, uye inoshandiswa zvakanyanya mukuvaka, makemikari, zvekurapa nedzimwe nzvimbo.
Simbi isina ngura yeAISI 904L inowanzo shandiswa muma reactors mumidziyo yepetroleum ne petrochemical; michina yekuchengetedza nekutakura sulfuric acid, senge zvinochinja-chinja kupisa; michina yekubvisa flue gas desulfurization mumagetsi, senge shongwe, maflue, ma shutter, zvikamu zvemukati, zvinopfapfaidza, mafeni, nezvimwewo muhurongwa hwekurapa organic acid; michina yekurapa mvura yegungwa, senge zvinochinja-chinja kupisa kwemvura yegungwa; michina yeindasitiri yemapepa, sulfuric acid, nitric acid; michina yemakemikari, midziyo yekumanikidza, michina yechikafu senge kugadzira acid uye maindasitiri emishonga.

Zvinotsanangurwa pakugadzirwa kweWomic Steel: Mapaipi esimbi isina ngura e904L anowanikwa muhukuru hwakasiyana-siyana hwekugadzira muWomic Steel Production line, kusanganisira mapaipi asina mativi uye mapaipi akasungirirwa. Dhayamita yekunze yemapaipi asina mativi inowanzova pakati pe3 kusvika 720 mm (φ1 kusvika 1200 mm), ine ukobvu hwemadziro hwe0.4 kusvika 14 mm; dhayamita yekunze yemapaipi akasungirirwa inowanzova pakati pe6 kusvika 508 mm, ine ukobvu hwemadziro hwe0.3 kusvika 15.0 mm.
Pamusoro pezvo, kunewo zvakasiyana-siyana zvakaita semapaipi ane sikweya nemapaipi erectangular, simbi ine simbi, maplate, macoil ane simbi isina ngura yekusarudza kwako muWomic Steel.
