I-SUS304 (i-SUS isho insimbi engagqwali yensimbi) i-austenite yensimbi engagqwali ivamise ukubizwa nge-SS304 noma i-AISI 304 ngesi-Japanese.Umehluko omkhulu phakathi kwalezi zinto ezimbili akuzona izinto ezibonakalayo noma izici, kodwa indlela ezicashunwe ngayo e-United States naseJapane.
Nokho, kukhona umehluko wemishini phakathi kwezinsimbi ezimbili.Esibonelweni esisodwa, amasampula e-SS304 atholwe emithonjeni yase-US kanye namasampula e-SUS304 atholwe emithonjeni yaseJapane athunyelwa elabhorethri ukuze ahlolwe.
I-SUS304 (i-JIS standard) ingenye yezinguqulo ezisetshenziswa kakhulu zensimbi engagqwali.Yakhiwe ngo-18% Cr (chromium) kanye no-8% Nickel (nickel).Isengakwazi ukugcina amandla ayo kanye nokumelana nokushisa emazingeni okushisa aphezulu naphansi.Iphinde ibe nokushisela okuhle, izakhiwo zokukhanda, ukusebenza kahle okubandayo kanye nokumelana nokugqwala ezingeni lokushisa legumbi. I-SS304 (ANSI 304) iyinsimbi engagqwali esetshenziswa kakhulu uma kwenziwa ezinye izinto zensimbi engagqwali, futhi ivamise ukuthengwa ngaphansi kwezimo ezibandayo noma zokuhoxisa.Ngokufanayo ne-SUS304, i-SS304 nayo iqukethe u-18% Cr no-8% Ni, ngakho ibizwa nge-18/8. I-SS304 inokushisela okuhle, ukumelana nokushisa, ukumelana nokugqwala, amandla okushisa aphansi, ukusebenza kahle, izakhiwo zemishini, ukwelashwa kokushisa akuqinisiwe, ukugoba, ukunyathela ukusebenza kwe-isothermal kuhle.I-SS304 isetshenziswa kabanzi ezimbonini eziningi, okuhlanganisa ukudla, umsebenzi wezokwelapha nowokuhlobisa. Ukwakhiwa kwamakhemikhali kwe-SUS304 ne-SS 304
| I-SUS304 | I-SS304 | |
| (C) | ≤0.08 | ≤0.07 |
| (Si) | ≤1.00 | ≤0.75 |
| (Mn) | ≤2.00 | ≤2.00 |

| (Ni) | 8.00-10.50 | 8.00-10.50 |
Ukumelana nokugqwala kwensimbi engagqwali engu-304 Njengoba sazi sonke, insimbi engagqwali engu-304 isebenza kahle ezindaweni ezihlukahlukene zomoya kanye nemithombo yezindaba egqwalayo.Kodwa-ke, endaweni efudumele ye-chloride, lapho izinga lokushisa lidlula ama-60 ° C, ijwayele ukugqwala, ukugqwala kwe-crevice kanye nokugqwala kwengcindezi.Ezingeni lokushisa elizungezile, kubhekwa futhi ukuthi iyakwazi ukumelana namanzi okuphuza aqukethe cishe ama-200 mg/l chloride.Izici zomzimba ze-SUS304 ne-SS304
Lezi zinto ezimbili zisondelene kakhulu ezintweni ezibonakalayo namakhemikhali, ngakho-ke kulula ukusho ukuthi ziyizinto ezifanayo.Ngokufanayo, umehluko omkhulu phakathi kwalawa mazwe womabili ukumisa phakathi kwe-United States neJapan.Lokhu kusho ukuthi ngaphandle uma imithetho ethile noma izimfuneko zicaciswe izwe noma ikhasimende, impahla ngayinye ingasetshenziswa ngenye indlela.
