Isingeniso ku
I-304 steel iyinsimbi engagqwali evame kakhulu, eyaziwa nangokuthi i-18/8 insimbi engagqwali embonini.Ukumelana nokugqwala kwayo kungcono kunensimbi engagqwali engu-430, kodwa intengo ishibhile kunensimbi engagqwali engu-316, ngakho-ke isetshenziswa kabanzi ekuphileni, njengokuthi: ezinye izitsha zensimbi ezingenasici ezisezingeni eliphezulu, izinsimbi zensimbi ezingenasici zangaphandle, njll. Nakuba insimbi engu-304 iyinsimbi evame kakhulu e-China, igama elithi "304 steel" livela e-United States.Abantu abaningi bacabanga ukuthi insimbi engu-304 yigama eliyimodeli eJapane, kodwa uma sikhuluma ngokuqinile, igama elisemthethweni lensimbi engu-304 eJapane lithi "SUS304".Insimbi engu-304 iwuhlobo lwensimbi engagqwali yendawo yonke, esetshenziswa kabanzi ekukhiqizeni izinto zokusebenza nezingxenye ezidinga ukusebenza okuhle okuphelele (ukumelana nokugqwala nokubumbeka).Ukugcina ukumelana nokugqwala okutholakala ensimbini engagqwali, insimbi kufanele ibe ne-chromium engaphezu kuka-16% kanye nokuqukethwe kwe-nickel engaphezu kuka-8%.I-304 insimbi engagqwali iwuphawu lwensimbi engagqwali ekhiqizwa ngokuhambisana nezinga le-ASTM laseMelika.304 ilingana 0Cr18Ni9 insimbi engagqwali ezweni lakithi.
Ukwakheka Kwamakhemikhali
Ibanga lamakhemikhali lensimbi engu-304 yi-06Cr19Ni10 (ibanga elidala -0Cr18Ni9) eliqukethe i-chromium engu-19% kanye ne-nickel engu-8-10%.

Izinga le
Insimbi engu-304 iyipharamitha ebaluleke kakhulu, inquma ngokuqondile ukumelana kwayo nokugqwala, kodwa futhi inquma inani layo.Izakhi ezibaluleke kakhulu ku-304 steel ziyi-Ni ne-Cr, kodwa azikhawulelwe kulezi zakhi ezimbili.Izimfuneko ezithile zicaciswa ngamazinga omkhiqizo.Ukwahlulela okuvamile kwemboni kukholelwa ukuthi inqobo nje uma okuqukethwe kwe-Ni kukhulu kune-8%, okuqukethwe kwe-Cr kukhulu kune-18%, kungabhekwa njengensimbi engu-304.Yingakho imboni ibiza lolu hlobo lwensimbi engagqwali 18/8 insimbi engagqwali.Eqinisweni, izindinganiso zomkhiqizo ezifanele ze-304 steel zinezinhlinzeko ezicacile kakhulu, futhi lezi zindinganiso zomkhiqizo zezinhlobo ezahlukene zensimbi engagqwali futhi kukhona umehluko.
