Imichilo yensimbi engagqwali 309kanye ne-310 zombili ziyi-alloys zensimbi engagqwali ye-austenitic engagqwali engamelana nokushisa, kodwa zinomehluko othile ekwakhiweni kwazo kanye nezicelo ezihlosiwe.309: Inikeza ukumelana okuhle nokushisa okuphezulu futhi ingaphatha amazinga okushisa afinyelela ku-1000°C (1832°F). Ivame ukusetshenziswa ezingxenyeni zesithando, kuma-heat exchanger, nasezindaweni ezishisa kakhulu.310: Inikeza ukumelana okungcono kakhulu nokushisa okuphezulu futhi ingamelana namazinga okushisa afinyelela ku-1150°C (2102°F). Ifaneleka ukusetshenziswa ezindaweni ezishisa kakhulu, njengezithando, ama-kiln, nama-radiant tubes.

Ngamafuphi, umehluko omkhulu phakathi kwezintambo zensimbi engagqwali 309 kanye no-310 usekwakhekeni kwazo kanye nokumelana nokushisa. I-310 inokuqukethwe okuphezulu kwe-chromium kanye ne-nickel, okwenza ifaneleke kangcono ekusetshenzisweni kokushisa okuphezulu kune-309. Ukukhetha kwakho phakathi kwalokhu okubili kuzoncika ezidingweni ezithile zesicelo sakho, kufaka phakathi izinga lokushisa, ukumelana nokugqwala, kanye nezakhiwo zemishini.
