Intsimbi engagqwaliyo 304 kunye ne-316 zombini ziintlobo ezidumileyo zentsimbi engagqwaliyo enomahluko owahlukileyo. Intsimbi engagqwaliyo 304 ine-18% ye-chromium kunye ne-8% ye-nickel, ngelixa intsimbi engagqwaliyo 316 ine-16% ye-chromium, i-10% ye-nickel, kunye ne-2% ye-molybdenum. Ukongezwa kwe-molybdenum kwintsimbi engagqwaliyo 316 kunika ukumelana okungcono nokugqwala, ngakumbi kwiindawo ze-chloride ezifana neendawo ezikunxweme nakwiindawo zoshishino.
Intsimbi engagqwaliyo 316 idla ngokukhethwa xa kufuneka uxhathiso olukhulu lokugqwala, njengeendawo zaselwandle, ukucubungula iikhemikhali, kunye nezixhobo zonyango. Kwelinye icala, intsimbi engagqwaliyo 304 isetyenziswa kakhulu kwizixhobo zasekhitshini, ekucubunguleni ukutya, kunye nezicelo zokwakha apho uxhathiso lokugqwala lubalulekile kodwa lungabalulekanga njengakwi-316.
Ngamafutshane, umahluko ophambili usekwe kwimilo yazo yeekhemikhali, nto leyo enika intsimbi engagqwali 316 ukumelana nokugqwala okuphezulu kwiindawo ezithile xa kuthelekiswa nentsimbi engagqwali 304.
