I-304 kanye ne-316 insimbi engagqwali yizinto ezimbili ezijwayelekile zensimbi engagqwali. Umehluko phakathi kwazo ikakhulukazi usekuhlanganiseni kwazo kwamakhemikhali nasezindaweni zokuzisebenzisa. Insimbi engagqwali engu-316 iqukethe i-chromium ne-nickel ephezulu kunensimbi engagqwali engu-304, eyenza insimbi engagqwali engu-316 ibe nokuvikeleka okungcono kokugqwala, ikakhulukazi ngokumelene nemidiya ye-chloride. Ngakho-ke, insimbi engagqwali engu-316 ifaneleka kakhulu ukusetshenziswa ezindaweni ezinezidingo eziphakeme zokumelana nokugqwala, njengezindawo zamanzi olwandle noma izimboni zamakhemikhali. Insimbi engagqwali engu-304 ivamise ukusetshenziswa ezinhlosweni ezijwayelekile ezifana nezinto zasekhishini, izinto zokwakha, njll.
Uma kukhulunywa ngo-304 futhi316 insimbi engagqwali, singafunda kabanzi mayelana nezici zabo zokusebenza. Ngokungeziwe ekwakhekeni kwamakhemikhali, lezi zinsimbi ezimbili ezingenasici nazo ziyahluka ekwakhekeni kwazo kwemishini nokucutshungulwa. I-316 insimbi engagqwali ngokuvamile inamandla aphezulu okuqinile namandla acindezelayo, kodwa ingaba nepulasitiki ephansi uma kuqhathaniswa. Ukwengeza, izakhiwo zokwelashwa kokushisa kwe-316 insimbi engagqwali aziguquki njengensimbi engagqwali engu-304, ngakho-ke ukunakwa okwengeziwe namakhono kungadingeka ekucubunguleni nasekubumbeni. Ngaphezu kwalokho, kunezinye izinhlobo zezinto zensimbi engagqwali, ezifana ne-304L ne-316L, ezinokuqukethwe kwekhabhoni ephansi futhi ezifaneleka kakhulu ukugwema ukukhiqizwa kwe-precipitates ngesikhathi sokushisela. Ngakho-ke, lapho ukhetha izinto zensimbi engagqwali, ngaphezu kokucabangela ukumelana kwayo nokugqwala, kuyadingeka futhi ukucabangela izakhiwo zayo zemishini, ukucubungula ukusebenza kanye nezidingo zezindawo ezithile zokufaka isicelo ukuze ukhethe izinto ezifanele kakhulu.
Lapho sijulisa ngokwengeziwe ukuqonda kwethu kwe-304 kanye ne-316 yensimbi engagqwali, singaphinde sicabangele izakhiwo zabo zokugqwala ezindaweni ezithile. Ngenxa yokuqukethwe kwe-molybdenum, insimbi engagqwali engu-316 ngokuvamile inokumelana nokugqwala okuphezulu kunensimbi engagqwali engu-304, ikakhulukazi ezindaweni eziqukethe ama-ion e-chloride, njengamanzi olwandle noma amanzi anosawoti. Lokhu kwenza316 insimbi engagqwaliukukhetha okufanelekile okuzosetshenziswa ezindaweni zasolwandle noma ezimbonini zamakhemikhali. Ukwengeza, umehluko wokusebenza walezi zinsimbi ezimbili ezingenasici ezindaweni ezisezingeni eliphezulu zingacutshungulwa ngokuqhubekayo, kanye nokusetshenziswa kwazo ezimbonini ezithile ezifana nokucubungula ukudla kanye nemishini yezokwelapha. Ngokuqonda okujulile, singakwazi ukukhetha ngokunembe kakhudlwana impahla yensimbi engagqwali efanele yezimo ezihlukene zohlelo lokusebenza ukuze siqinisekise ukuthi isebenza kahle kakhulu ezindaweni ezithile nezimo.
Ukukhetha i-304 noma i-316 yensimbi engagqwali kuncike ezidingweni ezithile zohlelo lokusebenza. Ngokuvamile, insimbi engagqwali engu-304 inokumelana nokugqwala okuhle futhi ifanele indawo evamile yasendlini nengaphandle, kuyilapho insimbi engagqwali engu-316 inokumelana nokugqwala okuphezulu ngoba iqukethe i-molybdenum futhi ifanele ukusetshenziswa ezindaweni ezigqwala kakhulu, njengamanzi olwandle. Imboni yezemvelo noma yamakhemikhali. Ngakho-ke, kuwumkhuba ongcono kakhulu ukukhetha i-304 noma i-316 yensimbi engagqwali ngokuya ngezimo ezithile zokusetshenziswa nezidingo.
