Insimbi engagqwali inokuqukethwe kwe-chromium okungenani okungu-10.5%, okuyenza imelane kakhulu nezindawo zoketshezi ezibolayo kanye ne-oxidation. Iyakwazi ukumelana nokugqwala futhi imelana nokugqokwa, ihlinzeka ngokusebenza kahle kakhulu, futhi yaziwa kakhulu ngokubukeka kwayo kobuhle. Ukulingwa kwensimbi engagqwali "ayikwazi ukugqwala" uma kusetshenziswa ezindaweni eziwuketshezi nezihwamuko ezingaphansi kuka-1200°F (650°C) kanye "nokumelana nokushisa" uma kusetshenziswa ngaphezu kwaleli zinga lokushisa.
Insimbi engagqwali ye-Austeniticibhekisela ensimbi engagqwali enesakhiwo se-austenitic ekamelweni lokushisa. Insimbi engagqwali ye-Austenitic ingelinye lamakilasi amahlanu ensimbi engagqwali ngesakhiwo sekristalu (kanye ne-ferritic, martensitic, duplex kanye nemvula eqinisiwe). Kwezinye izindawo, i-austentite insimbi engagqwali ibizwa nangokuthi i-300 series stainless steel. Lapho insimbi iqukethe cishe u-18% Cr, 8% -25% Ni, futhi cishe u-0.1% C, inesakhiwo esizinzile se-austenite. Insimbi engagqwali ye-Austenitic chromium-nickel ihlanganisa insimbi edumile engu-18Cr-8Ni kanye nensimbi yochungechunge lwe-Cr-Ni ephezulu ethuthukiswe ngokwengeza okuqukethwe kwe-Cr ne-Ni kanye nokwengeza i-Mo, Cu, Si, Nb, Ti nezinye izici kulesi sisekelo. Insimbi engagqwali ye-Austenitic ayinamagnetic futhi inokuqina okuphezulu kanye nepulasitiki, kodwa amandla ayo aphansi, futhi akunakwenzeka ukuyiqinisa ngokuguqulwa kwesigaba. Ingaqiniswa kuphela ngokusebenza okubandayo. Uma izakhi ezifana no-S, Ca, Se, Te zengezwa, zinezici ezinhle zokusebenziseka.
Insimbi engagqwali ye-Austenitic nayo ingakhiqiza ama-castings. Ukuze kuthuthukiswe i-fluidity yensimbi encibilikisiwe futhi kuthuthukiswe ukusebenza kokusakazwa, ukwakheka kwealloy yensimbi ecijile kufanele kulungiswe ngokukhuphula okuqukethwe kwe-silicon, kukhuliswe ububanzi bokuqukethwe kwe-chromium ne-nickel, nokukhulisa umkhawulo ongaphezulu wesici sokungcola sulphur.
Insimbi engagqwali ye-Austenitic kufanele iphathwe ngesixazululo esiqinile ngaphambi kokusetshenziswa, ukuze kwandiswe isisombululo esiqinile semvula ehlukahlukene njenge-carbides ensimbi ibe yi-austenite matrix, kuyilapho i-homogenizing isakhiwo futhi iqeda ingcindezi, ukuze kuqinisekiswe ukumelana nokugqwala okuhle kakhulu kanye izakhiwo zemishini. Uhlelo olulungile lokwelapha isixazululo ukupholisa amanzi ngemva kokushisisa ku-1050～1150℃ (izingxenye ezincanyana nazo zingapholiswa ngomoya). Izinga lokushisa lokwelapha isixazululo lincike ezingeni le-alloying yensimbi: I-molybdenum-free noma i-low-molybdenum steel amamaki kufanele abe ngaphansi (≤1100℃), kanye namamaki ahlanganisiwe aphezulu njenge-00Cr20Ni18Mo-6CuN, 00Cr25Ni22Mo2N, njll. kufanele abe phezulu ( 1080–1150) ℃).
Ipuleti lensimbi engagqwali i-Austenitic 304, okuthiwa iletha ukumelana nokugqwala okuqinile nokugqwala, futhi linobucwebe obuhle bepulasitiki nokuqina, olulungele ukugxivizwa nokubunjwa. Ngobuningi obungu-7.93 g/cm3, insimbi engagqwali engu-304 iyinsimbi evamile, eyaziwa nangokuthi insimbi engagqwali engu-18/8 embonini. Imikhiqizo yayo yensimbi imelana nokushisa okuphezulu futhi inezindawo ezinhle zokucubungula, ngakho-ke isetshenziswa kakhulu embonini nasezimbonini zokuhlobisa ifenisha kanye nezimboni zokudla nezokwelashwa.

Ukwelashwa Kokushisa Kwe-AISI 316 Stainless Steel Castings:
Shisisa kufike ku-1900°F (1040°C) ubuncane, ubambe isikhathi esanele, cisha emanzini noma uphole ngokushesha ngezinye izindlela. I-AISI 316 ilingana ne-CF8M/F316 kanye ne-Chinese Standard 0Cr17Ni12Mo2. I-AISI 314 iyingxube ye-molybdenum ehambisana ne-AISI 304 alloy futhi ilingana nensimbi eyenziwe nge-CF8M Stainless steel. Ukuba khona kwe-molybdenum kukhulisa ukumelana nokugqwala okujwayelekile kanye nokumelana nokugoba ngama-chloride. Ingxubevange isetshenziswa ezimweni ezine-asidi emnene kanye ne-alkaline nasekuphatheni ama-citric, i-oxalic kanye ne-phosphoric acid.
