304 ipuleti lensimbi engagqwali Izakhiwo eziyisisekelo:
Amandla okuqina (Mpa) 520
Amandla esivuno (Mpa) 205-210
Ubude (%) 40%
Ukuqina HB187 HRB90 HV200
304 ukuminyana kwensimbi engagqwali 7.93 g / cm3 austenitic insimbi engagqwali ngokuvamile zisebenzisa leli nani okuqukethwe kwe-chromium engu-304 (%) 17.00-19.00, okuqukethwe kwe-nickel.%) 8.00-10.00,304 okulingana ne-China's 0Cr19Ni0C stain809 (steel)
I-304 insimbi engagqwali iyinto ehlukahlukene yensimbi engagqwali, ukusebenza okulwa nokugqwala kunochungechunge lwama-200 lwezinto zensimbi engagqwali ukuze luqine.Izinga lokushisa eliphezulu nalo lingcono.
I-304 insimbi engagqwali inokumelana nokugqwala okuhle kakhulu nokumelana okuhle nokugqwala kwe-intergranular.
Ku-oxidation ye-asidi, ekuhlolweni kwaphetha: ukugxila ≤ 65% wezinga lokushisa elibilayo le-nitric acid, i-304 insimbi engagqwali inokumelana okuqinile nokugqwala.Isixazululo se-alkaline kanye nama-asidi amaningi e-organic kanye nama-asidi angaphili nawo anokumelana nokugqwala okuhle.
Izici ezijwayelekile
304 ukubukeka kwensimbi engagqwali kanye nokwenzeka kokuhlukahluka.
Ukumelana nokugqwala, okungcono kunensimbi evamile ehlala isikhathi eside, ukumelana nokugqwala okuhle.
Amandla aphezulu, ngakho-ke kungenzeka ukusetshenziswa kwepuleti elincane.
I-oxidation yokushisa ephezulu namandla aphezulu, ngakho ingavutha.
Ekucutshungulweni kwezinga lokushisa legumbi, lokho kulula ukukucubungula.
Ngenxa yokuthi akudingekile ukubhekana nayo, kulula futhi kulula ukuyigcina.
Hlanza, isiphetho esiphezulu.
Ukusebenza kwe-welding kuhle.
