304 Amabanga angenasici
Ukwakheka kwamakhemikhali: C: ≤0.08, SI: ≤1.0 MN: ≤2.0 MN: ≤2.0 ~ 20.0 ~ 20.0 ~ 20.0, 8.0 ~ 10.53, P: ≤0.035 N≤0.1.
Qhathanisa ne-304L
I-304L imelana nokuphikisana okuningi futhi iqukethe ikhabhoni encane.
I-304 isetshenziswa kabanzi futhi inokumelana kahle nokugqwala, ukumelana nokushisa, amandla okushisa aphansi kanye nezakhiwo zemishini; Inezakhiwo ezinhle zokuvutha ezishisayo njengokugxuma nokugoba, futhi akukho ukwelashwa okushisa okulondoloziwe okulondoloziwe (okungekho magnali, okushisa - sebenzisa izinga lokushisa -196 ° C ~ 800 ° C).
Ngemuva kokufudumala noma ukukhululeka kwengcindezi, u-304L unokumelana okuhle kakhulu ekugcuneni ngokwenhlangothi; Kungagcina ukumelana okuhle kokugqwala ngaphandle kokwelashwa okushisa, kanye nokushisa okusetshenzisiwe kungu -196 ° C-800 ° C.
Isimo Esiyisisekelo
Ngokusho kwendlela yokukhiqiza, ihlukaniswe ngokujikeleza okushisayo nokukhulisa okubandayo, futhi ngokwezici zenhlangano zohlobo lwensimbi, ihlukaniswe izigaba ezi-5: i-Auetenite, ArtEn-Ferrite, Ferrite, Martensite, Preciping Harding. Kuyadingeka ukubekezelela ukuwohloka kwama-acid ahlukahlukene afana ne-sulfate ye-oxalic acid, i-nitric acid-hydrofluoric, i-acetic acid, i-acetic acid, i-acetic acid, i-acetic acid, i-acectic acid, i-acec. Ama-Atomic Energy, kanye nezingxenye ezahlukahlukene zokwakha, izitsha zasekhishini, i-tableware, izimoto, kanye nemishini yasendlini.
Ingaphezulu lepuleti lensimbi engenasici libushelelezi, linoplastiki eliphakeme, ubulukhuni namandla emishini, futhi liyamelana nokugqwala ngama-acid, amagesi we-alkali, kanye neminye imithombo yezindaba. Kuyinsimbi ye-alley okungeyona lula ukugqwala, kepha akunamsebenzi ngokuphelele.
Amapuleti ensimbi angenasisekelo ahlukaniswe ngokugoqwa okushisayo futhi okubandayo ngokuya ngendlela yokukhiqiza, kufaka phakathi amapuleti akhudlwana anobukhulu obungu-0.02-4 mm namapuleti aphakathi nendawo anobukhulu obungu-4,5-100 mm.
Ukuze uqinisekise ukuthi izakhiwo zemishini zamapuleti ahlukahlukene ezinsimbi afana namandla wesivuno, amandla ashubile, ukusunduza kanye nobulukhuni kuhlangabezana nezidingo, amapuleti ensimbi kufanele abhekane nezindlela zokushisa ezinjengezokwelapha, kanye nokwelashwa kokuguga ngaphambi kokulethwa.
Ukumelana nokugqwala kwensimbi engenasici ikakhulukazi kuncike ekubukeni kwalo kwe-alloyimu (i-chromium, nickel, titanium, i-silico, i-aluminium, neqhaza eliphambili lenhlangano, kanye neqhaza eliphambili lidlalwa yi-chromium. I-Chromium inokuqina okuphezulu kwamakhemikhali futhi ingakha ifilimu yokuhamba ngensimbi endaweni yangaphandle, ihlukanisa insimbi evela ezweni langaphandle, ivikela ipuleti lensimbi kwi-oxidation, futhi yandise ukumelana nokugqwala kwepuleti lensimbi. Ngemuva kokuthi ifilimu yokudlula ichithiwe, ukumelana nokugqwala kuyancipha.

Ubuningi bensimbi engama-304 bungenacala 7.93 g / cm3 auntenitic insimbi engenacala ngokuvamile isebenzisa leli nsimbi 304 chromium (%) 17.00,00-19.00, 304 ilingana ne-0Cr199NI9 yezwe lami (0Cr18NI9)
I-304 Insimbi Engagqwali iyinto engabonakali yensimbi engenacala ngokumelana nokugqwala okunamandla kune-200 Series Izinto ezingenacala. Kungcono futhi ekumelaneni nokushisa okuphezulu.
Insimbi engenacala inokumelana kahle nokugqwayiza okungagqwali nokumelana okuhle kokugqwala.
Nge-oxidizing acid, ukuhlolwa kukhombisa ukuthi: ku-nitric acid ngezansi kokushisa okubilayo nge-≤65%, 304 Insimbi engenasici inamandla okuqina okuqinile. Futhi inokumelana kahle nokuphikiswa kwezixazululo ze-Alkaline kanye nama-organic kanye nama-acid ahlukahlukene.
Izici ezijwayelekile
I-304 I-Plate Engagqwali yensimbi inendawo enhle kanye namathuba ahlukahlukene okusebenzisa
