321 bir ah 4.0 * 0.35 mm tube duuban
321 waa titanium xasiloon chromium-nickel austenitic bir aan lahayn xoog wanaagsan iyo iska caabin daxalka aad u fiican, sida la keeno in xaaladda annealed la annealed adag brinell caadiga ah ee 175. Characterized by iska caabin daxalka sare ee jawiga daxalka guud ee jawiga waxay muujinaysaa iska caabin aad u fiican in oxidizing ugu. wakiilada, cuntada guud, xal sterilization, dheeha, inta badan kiimikooyinka organic iyo noocyo kala duwan oo kiimikooyin ah inorganic, sidoo kale gaaska batroolka kulul, uumiga gubanaya, nitric acid, iyo ilaa xad ka yar sulfuric acid.Waxay soo bandhigaysaa iska caabbinta oksaydheynta wanaagsan ee heerkulka sare leh waxay leedahay iska caabin aad u wanaagsan oo u leh daxalka intergranular waxayna leedahay alxanka wanaagsan.321 laguma adkeyn karo daawaynta kulaylka, laakiin xoogga iyo adkaanta waxaa lagu kordhin karaa si la taaban karo iyadoo qabow la shaqeeyo, iyadoo hoos u dhac ku yimaada ductility.
Si weyn loogu isticmaalo codsiyada halka ku darida titanium iyo saameynteeda xasilinta sida curiyaha samaynta carbide ay u ogolaato in la alxanayo iyo/ama loo isticmaalo qiyaasta roobabka carbide 430oC – 870oC iyada oo aan lahayn khatarta daxalka intergranular.Kuwaas waxaa ka mid ah Habaynta Cuntada, Qalabka Caanaha, Kiimikada, Kiimikada Batroolka, Gaadiidka iyo warshadaha la xidhiidha iwm.
Walxaha aan magnetic-ka ahayn ee ku jira xaaladda la tirtiray, laakiin waxay noqon kartaa birlab khafiif ah ka dib shaqeynta qabow culus.
Annealing ayaa loo baahan yahay si loo saxo haddii loo baahdo.
NB Iska caabbinta daxalka ugu fican ayaa lagu gaaraa xaalada la daboolay.
