321 xaashida birta ah ee aan lahayn 2b Ba Dhamaystir
Sharaxaada
Alloy 321 (UNS S32100) waa saxan bir ah oo xasilan oo bixisa faa'iidada ugu weyn ee iska caabinta daxalka intergranular ka dib soo-gaadhista heerkulka roobabka chromium carbide ee u dhexeeya 800 ilaa 1500 ° F (427 ilaa 816 ° C).Alloy 321 saxan bir ah oo aan lahayn ayaa la xasiliyay ka soo horjeeda samaynta chromium carbide iyadoo lagu daro titanium.
Alloy 321 saxan bir ah oo aan lahayn ayaa sidoo kale faa'iido u leh adeegga heerkulka sare sababtoo ah sifooyinka farsamada ee wanaagsan.Alloy 321 saxan bir ah oo bir ah ayaa bixisa gurguurta sare iyo guryaha dillaaca walaaca marka loo eego Alloy 304 iyo, gaar ahaan, Alloy 304L, kaas oo sidoo kale laga yaabo in loo tixgeliyo muujinta halka dareenka iyo daxalka intergranular ay walaac ka qabaan.
321 saxan bir ah oo aan lahayn Ti sida curiye xasilin ah ayaa jira, laakiin sidoo kale waa darajada birta kulul, heerkulka sare wuxuu ka fiican yahay 316 l saxan bir ah.321 saxan bir ah oo kala duwan oo diirada iyo heerkulka kala duwan ee acid organic iyo inorganic acid, gaar ahaan in dhexdhexaad ah oxidizing ayaa iska caabin wanaagsan abrasion, loo isticmaalo in wax soo saarka ee xirashada weelasha acid adkaysta iyo qalabka.
321 saxan bir ah oo bir ah waa Ni-Cr-Mo austenitic saxan bir ah, waxqabadkeedu wuxuu la mid yahay 304 saxan bir ah, laakiin sababtoo ah ku darista birta titanium, waxay leedahay iska caabin xad dhaaf ah oo hadhuudh ah iyo xoog heerkul sare ah.Samaynta carbide chromium si wax ku ool ah ayaa loo xakameeyaa iyadoo lagu darayo birta titanium.
