Alloy 321 (UNS S32100) waa titanium xasiloon austenitic ahama oo leh iska caabin guud oo wanaagsan. Waxay leedahay iska caabin heer sare ah oo ay u leedahay daxalka intergranular ka dib soo-gaadhista heerkulku wuxuu u dhexeeyaa roobabka chromium carbide ee 800 – 1500°F (427 – 816°C). Daawaha waxay ka hortagtaa oksaydheynta ilaa 1500°F (816°C) waxayna leedahay gurguurta iyo kadeedka guryaha dilaaca marka loo eego alloys 304 iyo 304L. Waxa kale oo ay leedahay adkeyd heerkul hoose oo wanaagsan.
Alloy 321H (UNS S 32109) waa kaarboonka sare (0.04 - 0.10) nooca daawaha. Waxaa loo sameeyay iska caabin gurguurta oo la xoojiyey iyo xoog sare oo heerkul ka sarreeya 1000oF (537°C). Xaaladaha intooda badan, kaarboonka ku jira saxanku waxa uu saamaxaa laba-shahaado.
Alloy 321 laguma adkeyn karo daawaynta kulaylka, kaliya iyadoo qabow lagu shaqeeyo. Si fudud ayaa loo alxan karaa oo looga baaraandegi karaa hab-dhaqannada wax-soo-saarka dukaanka caadiga ah.
