I-AISI 904L insimbi engagqwali noma i-AISI 904L (WNR1.4539) ASTM A 249, N08904, X1NiCrMoCu25-20-5 iyinsimbi engagqwali ephezulu ye-alloy austenitic. Uma kuqhathaniswa ne-316L, i-SS904L inokuqukethwe kwekhabhoni (C) ephansi, okuqukethwe kwe-chromium (Cr) ephezulu, futhi cishe okuphindwe kabili kokuqukethwe kwe-nickel (Ni) ne-molybdenum (Mo) okungu-316L, okukunikeza izinga lokushisa eliphezulu...
904L (N08904,, 14539) super austenitic insimbi engagqwali iqukethe 19.0-21.0% chromium, 24.0-26.0% nickel, kanye 4.5% molybdenum. I-904L super austenitic insimbi engagqwali iyikhabhoni ephansi, i-nickel ephezulu, insimbi engagqwali ye-molybdenum austenitic engamelana ne-asidi, okuyingxenye yobunikazi eyethulwe enkampanini yase-French H·S. Inekhono elihle lokuguqula i-activation-passivation, ukumelana nokugqwala okuhle kakhulu, ukumelana nokugqwala okuhle kuma-asidi anga-oxidizing njenge-sulfuric acid, i-acetic acid, i-formic acid, i-phosphoric acid, ukumelana okuhle kwe-pitting ku-neutral chloride ion media, kanye nokugqwala okuhle kokugqwala nokumelana nokugqwala kwengcindezi. Ifanele ukugxila okuhlukahlukene kwe-sulfuric acid engaphansi kuka-70 ° C, futhi inokumelana nokugqwala okuhle kwe-acetic yanoma yikuphi ukugxila nanoma yikuphi ukushisa ngaphansi kwengcindezi evamile, kanye ne-asidi exubile ye-formic acid ne-acetic acid.
I-AISI 904L insimbi engagqwali iyinsimbi engagqwali enengxubevange ephezulu ye-austenitic enokuqukethwe kwekhabhoni ephansi kakhulu. Inhlanganisela ye-chromium ephezulu, i-nickel, i-molybdenum nethusi inikeza insimbi ukumelana nokugqwala okuhle okufanayo. Ukwengezwa kwethusi kuyenza ibe nokumelana ne-asidi eqinile, ingamelana nama-acids ahlukahlukene ezinto eziphilayo kanye ne-inorganic, ikakhulukazi ukugqwala kwe-chloride crevice kanye nokuqhekeka kokugqwala kwengcindezi, akulula ukuba namabala nokuqhekeka kokugqwala, futhi inokumelana nokugoba okuqinile. I-AISI 904L inokumelana nokugqwala okuhle ku-dilute sulfuric acid. Ingxubevange iyinsimbi elungele ukuxubha i-sulfuric acid eqinile edlayo. Iphinde imelane namanzi olwandle, inokusebenza okuhle nokushisela, futhi isetshenziswa kabanzi ekwakhiweni, kwamakhemikhali, kwezokwelapha nakwezinye izimboni.
I-AISI 904L insimbi engagqwali ivame ukusetshenziswa kuma-reactors ku-petroleum kanye nemishini ye-petrochemical; isitoreji se-sulfuric acid kanye nemishini yokuthutha, njengezishintshi zokushisa; imishini ye-flue gas desulfurization ezitshalweni zamandla, njengemibhoshongo, ama-flue, ama-shutter, izingxenye zangaphakathi, izifutho, amafeni, njll. ezinhlelweni zokwelashwa kwe-asidi ye-organic; izinto zokuhlanza amanzi olwandle, njengezishintshisi zokushisa zamanzi olwandle; imishini yemboni yephepha, i-sulfuric acid, imishini ye-nitric acid; imishini yamakhemikhali, imikhumbi yokucindezela, izinto zokudla ezifana nokwenza i-asidi nezimboni zemithi.

Imininingwane yokukhiqiza yi-Womic Steel: Amapayipi ensimbi engagqwali angu-904L atholakala ngamasayizi ahlukahlukene okukhiqiza kulayini Wokukhiqiza Insimbi ye-Womic, okuhlanganisa amapayipi angenamthungo namapayipi ashiselwe. Ububanzi bangaphandle bamapayipi angenamthungo ngokuvamile busukela ku-3 kuye ku-720 mm (φ1 kuya ku-1200 mm), obunodonga obungu-0.4 kuya ku-14 mm; ububanzi obungaphandle bamapayipi ashiselwe ngokuvamile busukela ku-6 kuya ku-508 mm, nobukhulu bodonga obungu-0.3 kuya ku-15.0 mm.
Ngaphezu kwalokho, kuphinde kube nokucaciswa okuhlukahlukene okunjengamapayipi ayisikwele namapayipi angunxande, ibha yensimbi, amapuleti, amakhoyili anempahla yensimbi engagqwali ozikhethele yona ku-Womic Steel.
