ASTM A638 660 Birta Aanaylahayn
Sharaxaad Gaaban:
660A waxaa loola jeedaa xaalad gaar ah oo ah A286 alloy (UNS S66286), kaas oo ah bir aan lahayn oo xoog leh, heerkul sare leh, iyo daxal u adkaysta.
660A Birta Birta Ah:
ASTM A453 Fasalka 660 waa roobab adag oo adag austenitic ahama birta si ballaaran loo isticmaalo xiritaanka heerkul sare iyo qalabka bolting. Xaaladda 660A ee birta A286 waa xal la dajiyay, taasoo bixisa dheelitirnaan xoog sare leh, qaabayn wanaagsan, iyo iska caabin daxalka aad u fiican. Tani waxay ka dhigaysaa mid ku habboon dalabaadka codsiyada hawada, baabuurta, iyo qaybaha warshadaha halkaas oo alaabtu ay tahay inay si kalsooni leh u qabtaan xaaladaha heerkulka sare iyo heerkulka sare. Caabbin heer sare ah oo ku saabsan oxidation iyo daxalka jawiga heerkulka sare leh.
