Sharaxaada Alaabta
Ka dib marka lagu daro Ti oo ah walxo xasilin, 321 birta aan fiicnayn waxay soo bandhigaysaa awood kulul oo aad u fiican, taas oo ka fiican birta 316L.Waxay leedahay iska caabin aad u wanaagsan oo ku saabsan asiidhyada organic iyo inorganic ee kala duwan xitaa heerkul iyo heerkul kala duwan.Intaa waxaa dheer, Nooca 321 birta aan-lahayn ayaa si gaar ah waxtar ugu leh deegaanka oksaydheynta.Tani waxay ka dhigaysaa mid ku habboon samaynta weelasha u adkaysta aashitada, dahaarka qalabka iyo tuubooyinka.
Waxyaabaha ay ka kooban tahay 321 birta aan la taaban karin waxaa ka mid ah nikkel (Ni), chromium (Cr) iyo titanium (Ti), taas oo ah daawaha birta aan lahayn austenitic.Si la mid ah 304 bir aan-ka-soo-bax ah oo leh sifooyin la mid ah.Si kastaba ha ahaatee, ku darida titanium waxay hagaajinaysaa caabbinta daxalka ee xuduudaha hadhuudhka waxayna kor u qaadaysaa xooggeeda heerkulka sare.Ku darida titanium si wax ku ool ah ayaa looga hortagayaa samaynta chromium carbides ee daawaha.
321 birta aan dahsoon waxay leedahay sifooyin aad u wanaagsan marka loo eego dillaaca diiqad heerkul sare ah iyo iska caabin gurguurta.Sifooyinkeeda makaanik ee hoos yimaada xaaladaha heerkulka sare waxay ka badan yihiin kuwa 304 birta aan lahayn.Sidaa darteed, waxay ku habboon tahay codsiyada alxanka ee ku lug leh qaybaha ka shaqeeya heerkulka sare.
