321 ibyuma bidafite ingese 4.0 * 0,35 mm ya tariyeri yatetse
321 ni titanium itunganijwe neza ya chromium-nikel austenitike ibyuma bitagira umuyonga hamwe nimbaraga nziza hamwe no kurwanya ruswa nziza, nkuko byatanzwe muburyo bwa anneed hamwe nuburemere busanzwe bwa brinell ya 175.Birangwa no kurwanya ruswa nyinshi mubidukikije rusange byangiza ikirere byerekana imbaraga zirwanya okiside nyinshi. ibikoresho, ibiribwa rusange, ibisubizo bya sterilisation, dyestuffs, imiti myinshi kama hiyongereyeho ubwoko butandukanye bwimiti mvaruganda, na gaze ya peteroli ishyushye, imyuka yaka amavuta, aside nitricike, hamwe na acide sulfurique.Irerekana okiside nziza yubushyuhe bwo hejuru ifite imbaraga zo kurwanya ruswa kandi ikagira gusudira neza.321 ntishobora gukomera no kuvura ubushyuhe, ariko imbaraga nubukomezi birashobora kwiyongera cyane kubikorwa bikonje, hamwe no kugabanuka guhindagurika.
Ikoreshwa cyane mubisabwa aho kongeramo titanium ningaruka zayo zihamye nkibintu bigize karbide ituma ishobora gusudwa kandi / cyangwa gukoreshwa murwego rwimvura ya karbide 430oC - 870oC udafite ibyago byo kwangirika hagati.Harimo gutunganya ibiribwa, ibikoresho byamata, imiti, peteroli, ubwikorezi ninganda zijyanye nabyo nibindi.
Ibikoresho bitari magnetique muburyo bwa annealed, ariko birashobora guhinduka magnetique yoroheje nyuma yubukonje bukabije.
Annealing irasabwa gukosora nibiba ngombwa.
NB Kurwanya ruswa nziza kugerwaho muburyo bwa annealed.
