Intangiriro kuri
Ti ya 321 ibyuma bidafite ingese ibaho nkibintu bihamye, ariko kandi nicyuma gikoresha ubushyuhe, kikaba cyiza cyane kuruta 316L.321 ibyuma bidafite ingese bifite imbaraga zo kurwanya abrasion muri acide kama na acide organic organique yibitekerezo hamwe nubushyuhe butandukanye, cyane cyane mubitangazamakuru bya okiside, bikoreshwa mugukora ibikoresho bya aside irwanya kwambara hamwe nibikoresho bitarinda kwambara.
321 ibyuma bidafite ingese ni Ni-Cr-Ti austenitike ibyuma bitagira umuyonga, imikorere yayo irasa cyane na 304, ariko kubera kongeramo icyuma cyitwa titanium, kuburyo gifite imipaka myiza yo kurwanya ruswa no gukomera kwinshi.Bitewe no kongeramo ibyuma bya titanium, bigenzura neza imikorere ya chromium karbide.
321 ibyuma bidafite ingese bifite ubushyuhe buhanitse bwo hejuru Stress Rupture imikorere nubushyuhe bwo hejuru Creep Resistance stress mikoranike iruta ibyuma 304.Irakwiriye gusudira ibice bikoreshwa mubushyuhe bwinshi.
