I-Hot Rolled Flat Steel Origin in China insimbi eyisicaba eminye imikhiqizo ibha yensimbi engagqwali

304 insimbi engagqwali ifilimu yokuvimbela ukugqwala kwensimbi, ukuze kuvikelwe insimbi ngokwayo ngendawo yangaphandle yomoya (ikakhulukazi umoya-mpilo), amanzi, i-asidi ethile, ukugqwala kwe-alkali oxidation.

Insimbi engagqwali yendawo yonke, isetshenziswa kabanzi ekwakhiweni kwemishini kanye nezingxenye ezidinga inhlanganisela enhle yezakhiwo (ukumelana nokugqwala nokubumba).Ingakwazi ukumelana nokugqwala okuvamile esakhiweni, ingamelana nokuguguleka kwemidiya yokucubungula ukudla (kodwa iqukethe izingxenye ze-asidi egxilile kanye ne-chloride ingase ibe nokugqwala emazingeni okushisa aphakeme), ingamelana nezinhlanganisela zezinto eziphilayo, odayi kanye nezinhlobonhlobo zezinto ezingaphili.Thayipha i-304L (ikhabhoni ephansi), ukumelana kahle ne-nitric acid, kanye nezinga lokushisa elihlala isikhathi eside kanye nokugcwala kwe-sulfuric acid, esetshenziswa kabanzi njengethangi lokugcina igesi ewuketshezi, esetshenziswa kumishini ye-cryogenic (304N), izinto zikagesi neminye imikhiqizo yabathengi, okokusebenza kwasekhishini, okokusebenza kwasesibhedlela. , ezokuthutha, izinto zokuhlanza amanzi angcolile.I-304 iyinsimbi engagqwali yendawo yonke, esetshenziswa kabanzi ekwenzeni izinto zokusebenza nezingxenye ezidinga izakhiwo ezinhle eziphelele (ukumelana nokugqwala nokubumbeka).Insimbi engagqwali engu-301 ikhombisa ukuqina komsebenzi okusobala ngesikhathi sokuguqulwa, okusetshenziswa ezikhathini ezahlukahlukene ezidinga amandla aphezulu.Insimbi engagqwali engu-304 iwuhlobo lwensimbi engagqwali engama-304 enokuqukethwe kwekhabhoni ephezulu, engathola amandla aphakeme ngokugoqeka okubandayo.

I-304L iwuhlobo lwensimbi engagqwali engu-304 enokuqukethwe kwekhabhoni ephansi futhi isetshenziselwa izinhlelo zokushisela.Okuqukethwe kwekhabhoni ephansi kubangela ama-carbides amancane atholakala endaweni ethintekile ekushiseni eduze nendawo yokushisela, okungase kubangele ukugqwala kwe-intergranular (ukuguguleka kokushisela) kwensimbi engagqwali kwezinye izindawo.I-304N iyinsimbi engagqwali equkethe i-nitrogen, i-nitrogen yengezwa ukuze kuthuthukiswe amandla ensimbi.Insimbi engagqwali engu-304 eyisicaba iqukethe i-nickel ephakeme, izinga layo lokuqina lomsebenzi liphansi, lilungele izidingo zokwakheka okubandayo ngezikhathi ezahlukahlukene.
