I-304/304L iyinsimbi engagqwali ye-Austenitc esetshenziswa kakhulu.Ibala ngaphezu kuka-50% yazo zonke insimbi engagqwali ekhiqizwayo, imele phakathi kuka-50% -60% wokusetshenziswa kwezinto ezingagqwali kanye nama-fins application cishe kuyo yonke imboni.I-304L iyikhemikhali yekhabhoni ephansi engu-304, ihlanganiswa nokwengezwa kwe-nitrogen yenza i-304L ihlangabezane nezakhiwo zemishini engu-304. 304L evame ukusetshenziswa ukugwema ukugqwala okungaba khona kokuzwela ezintweni ezishiselwe. kancane kazibuthe ngenxa yokusebenza okubandayo noma ukushisela.Ingakwazi ukushiselwa kalula futhi icutshungulwe ngezinqubo ezijwayelekile zokwenziwa.Inokumelana okuhle kakhulu nokugqwala komkhathi, izindawo ezikhiqiza i-oxidizing ngokulinganisela nokunciphisa, kanye nokugqwala kwe-intergranular ku-conition as-welded Iphinde ibe namandla amakhulu kakhulu kanye nokuqina emazingeni okushisa e-cryogenic futhi.
