Uhlobo lwe-321 (UNS S32100) kwi-Coil tubing
Inkcazo
Uhlobo lwe-321 yi-titanium ezinzile i-chromium nickel i-austenitic insimbi engenasici kunye nokumelana nokubola okufana ne-304 / 304L.Eli bakala lidla ngokusetyenziswa kwi-800-1500˚F kuluhlu lobushushu apho lizinziswa ngokuchasene nemvula ye-chromium carbide ngokongezwa kwe-titanium, ekhokelela kwimvula ye-titanium carbides.Uhlobo lwe-321 lunokumelana okugqwesileyo kwe-intergranular corrosion emva kokuvezwa kolu luhlu lobushushu, kwaye eli nqanaba lixhathisa i-oxidation ukuya kuthi ga kwi-1500˚F kwaye lineempawu eziphezulu zokurhubuluza kunye noxinzelelo lokukrazula kune-304/304L.Ikwanayo nokuqina okuhle kobushushu obuphantsi kwaye ayinamagnetic kwimeko efakwe kwi-annealed.
321 intsimbi engatyiwayo ebhijelwe ityhubhu
