321 chitsulo chosapanga dzimbiri 4.0 * 0.35 mm chubu chophimbidwa
321 ndi titaniyamu wokhazikika chromium-nickel austenitic chitsulo chosapanga dzimbiri chokhala ndi mphamvu zabwino komanso kukana dzimbiri bwino, monga amaperekedwa mumkhalidwe wokhazikika wokhala ndi kuuma kwa brinell wa 175. Wodziwika ndi kukana kwa dzimbiri muzambiri zam'mlengalenga zowononga zambiri zomwe zimawonetsa kukana kwamphamvu kwambiri mumlengalenga. mankhwala, zakudya wamba, mankhwala ophera tizilombo, utoto, mankhwala ambiri achilengedwe kuphatikiza mitundu ingapo yamankhwala osakhazikika, komanso mpweya wotentha wamafuta, mpweya woyaka ndi nthunzi, asidi wa nitric, komanso pang'ono asidi wa sulfuric.Imawonetsa kukana kwa okosijeni kwabwino pa kutentha kokwezeka imakhala ndi kukana kwambiri kwa intergranular corrosion ndipo imakhala ndi weldability kwambiri.321 silingaumitsidwe ndi chithandizo chamankhwala, koma mphamvu ndi kuuma kumatha kuonjezeredwa kwambiri ndi kugwira ntchito kozizira, ndikuchepetsanso ductility.
Amagwiritsidwa ntchito kwambiri pamapulogalamu pomwe kuwonjezera kwa titaniyamu ndi kukhazikika kwake ngati chinthu chopangira carbide kumalola kuti aziwotcherera ndi / kapena kugwiritsidwa ntchito mkati mwa carbide precipitation range 430.oC -870oC popanda chiopsezo cha intergranular dzimbiri.Izi zikuphatikiza Kukonza Chakudya, Zida Zamkaka, Chemical, Petrochemical, Transport ndi mafakitale ogwirizana ndi ena.
Zinthu zosakhala ndi maginito zomwe zimayikidwa, koma zimatha kukhala maginito pang'ono potsatira kuzizira kwambiri.
Kuwongolera kumafunika kukonzanso ngati kuli kofunikira.
NB Optimum corrosion resistance imatheka mukakhala annealed.
