Insimbi engagqwali 304 kanye ne-316 womabili amamaki adumile ensimbi engagqwali anomehluko ohlukile. Insimbi engagqwali 304 iqukethe 18% chromium kanye 8% nickel, kuyilapho insimbi engagqwali 316 iqukethe 16% chromium, 10% nickel, kanye 2% molybdenum. Ukwengezwa kwe-molybdenum kunsimbi engagqwali 316 kunikeza ukumelana okungcono nokugqwala, ikakhulukazi ezindaweni ezine-chloride njengezindawo ezisogwini nezimboni.
Insimbi engagqwali engu-316 ivamise ukukhethwa ukuze isetshenziswe lapho kudingeka ukumelana nokugqwala okuphezulu, njengendawo yasolwandle, ukucubungula amakhemikhali, kanye nemishini yezokwelapha. Ngakolunye uhlangothi, insimbi engagqwali engu-304 ivamise ukusetshenziswa emishinini yasekhishini, ekucubunguleni ukudla, nasekusetshenzisweni kwezakhiwo lapho ukumelana nokugqwala kubalulekile kodwa hhayi okubucayi njengaku-316.
Kafushane, umehluko omkhulu usekuhlanganiseni kwawo kwamakhemikhali, okunikeza insimbi engagqwali engu-316 ukumelana nokugqwala okuphakeme ezindaweni ezithile uma kuqhathaniswa nensimbi engagqwali engu-304.
