321 waa titanium xasiloon austenitic chromium-nickel birta loo sameeyay si ay u bixiso 18-8 nooc daawaha leh hagaajinta iska caabinta intergranular-daxalka. Sababtoo ah titanium waxay leedahay xiriir adag oo kaarboon marka loo eego chromium, titanium carbide waxay u egtahay inay si aan kala sooc lahayn ugu soo degto badarka halkii ay ka samayn lahayd qaababka joogtada ah ee xuduudaha badarka.321 waa in loo tixgeliyo codsiyada u baahan kuleyl dhexdhexaad ah inta u dhaxaysa 8009F (427°C) iyo 1650°F (899°C)
