321 Rau Kowiri tira 2b Ba Mutu
Whakaahuatanga
Ko te Alloy 321 (UNS S32100) he mea whakapumau te pereti kowiri tira e tuku ana hei painga nui ki te aukati i te waikura intergranular whai muri i te rongonga ki te pāmahana i roto i te awhe rerenga chromium carbide mai i te 800 ki te 1500°F (427 ki te 816°C).Ko te paraharaha kowiri tira 321 ka whakapumau ki te hanga chromium carbide ma te taapiri o te titanium.
Ko te paraharaha kowiri tira 321 he pai hoki mo te ratonga pāmahana teitei na te mea he pai nga taonga miihini.Ko te paraharaha kowiri tira Alloy 321 he nui ake te ngokingoki me te pakaru o te ahotea i te Alloy 304 me, otira, Alloy 304L, tera pea ka whakaarohia mo nga whakaaturanga kei te awangawanga te whakamaarama me te waikura waenga.
321 pereti kowiri tira o Ti rite te huānga pūmau te vai, engari he ano he kōeke rino wera, i roto i te pāmahana teitei he pai atu i te 316 l pereti kowiri tira.321 pereti kowiri tira i roto i te kukū rerekē me te pāmahana o te waikawa waro me te waikawa pararopi, rawa i roto i te reo oxidizing he ātete abrasion pai, whakamahia i roto i te hanga o te mau ipu waikawa ātete me te taputapu.
321 pereti kowiri tira ko Ni-Cr-Mo austenitic pereti kowiri tira, he tino rite tona mahi ki te 304 pereti kowiri tira, engari na te mea o te taapiri o te whakarewa titanium, he pai ake te parenga o te rohe o te witi me te kaha o te wera.Ko te hanganga o te chromium carbide he pai te whakahaere ma te taapiri i te whakarewa titanium.
