Ukwakheka kwamakhemikhali kwe-304 insimbi engagqwali C ≤ 0.08 Si ≤ 1.00 Mn ≤ 2.00 P ≤ 0.05 S ≤ 0.03 Cr 18.00-20.00 Ni (nickel) 8.00~10.50 -;
Ukwakheka kwamakhemikhali kwe-304L yensimbi engagqwali yi-% C: ≤ 0.03, Si: ≤ 1.0, Mn: ≤ 2.0, Cr: 17.0 ～ 19.0, Ni: 8.0 ～ 11.0, S: ≤ 0.050: P.05: P.
Kungabonakala ukuthi izingxenye eziyinhloko ze-304 insimbi engagqwali kanye ne-304L yensimbi engagqwali yi-18% chromium (Cr) ne-8% nickel (Ni);Umehluko omkhulu phakathi kwabo ukuthi i-304L insimbi engagqwali iyinsimbi ephansi ye-carbon 304.Ngokuvamile, ukumelana nokugqwala kwe-304L yensimbi engagqwali kufana nensimbi engagqwali engu-304, kodwa ngemva kokushisela noma ukukhululeka kwengcindezi, ukumelana nokugqwala komngcele wokusanhlamvu wensimbi engagqwali engu-304L muhle kakhulu.
Ngokwenani, insimbi engagqwali engu-304L ingaphezulu kuka-304 insimbi engagqwali, futhi insimbi engagqwali engu-304L iyinsimbi engenakhabhoni ephansi, esebenza kakhulu enqubweni yokushisela.Lapho ushisela, insimbi engagqwali engu-304L inganciphisa ngempumelelo ukugqwala kokushisela.
Ngokwezinga lokuqina, insimbi engu-304 ingcono kunensimbi engagqwali engu-304L, ngoba okuqukethwe kwekhabhoni kuthinta ngqo ubulukhuni bensimbi engagqwali.Ngaphezu kwalokho, kukhona uchungechunge lwensimbi engagqwali engu-304H.U-H ukhombisa okuqukethwe kwekhabhoni ephezulu.
Ngokwesicelo, i-304: 0Cr18Ni9, njengensimbi enezinhlobonhlobo zezicelo, inokumelana nokugqwala okuhle, ukumelana nokushisa, amandla okushisa aphansi kanye nezakhiwo zemishini;Ukunyathela, ukugoba nokunye ukusebenza okushisayo kuhle, futhi asikho isenzo sokuqina sokwelashwa kokushisa (okungewona uzibuthe, izinga lokushisa lokusebenzisa elingu- – 196 ℃~800 ℃).Izihloko zasendlini (I-tableware yekilasi 1 nelesi-2, amakhabethe, amapayipi asendlini, izifudumezi zamanzi, amabhayela, obhavu), izingxenye zezimoto (amawipha-windshield, ama-muffler, imikhiqizo ebunjiwe), izinto zokwelapha, izinto zokwakha, amakhemikhali, imboni yokudla, ezolimo, nezingxenye zemikhumbi .
I-304L: 00Cr19Ni10 iyinsimbi ephansi ye-C 304.Ngokuvamile, ukumelana nokugqwala kwayo kufana nensimbi engu-304, kodwa ngemva kokushisela noma ukukhululeka kwengcindezi, ukumelana nokugqwala komngcele wayo wokusanhlamvu kuhle kakhulu;Ingakwazi futhi ukugcina ukumelana nokugqwala okuhle ngaphandle kokwelashwa kokushisa, futhi izinga lokushisa lesevisi lingu-196 ℃～ 800 ℃.
Isetshenziswa emishinini yangaphandle ezimbonini zamakhemikhali, zamalahle nezephethiloli ezinezidingo eziphezulu zokumelana nokugqwala komngcele wokusanhlamvu, izingxenye ezimelana nokushisa zezinto zokwakha kanye nezingxenye zero ezinobunzima ekwelapheni ukushisa.
