Astm a638 660 baarka birta aan cillad lahayn
Sharraxaadda Gaaban:
660A waxaa loola jeedaa xaalad gaar ah oo ka mid ah A286 ASITOY (NEM8286), oo ah xoog sare, heerkul sare, iyo bir-u-adkeysi u adkaysata.
660a oo bir bir ah:
ASTM A453 Fasalka 660 ayaa ah roobab adag oo adkeeya birta austenitic-ka ah ee loo yaqaan 'austenitic' birta si weyn loo isticmaalo si heer kul ah oo heerkul sare ah iyo agab xiritaan. Status 660a ee birta-qalooca ee A286 waa xalka la duqeeyey, iyadoo la siinayo isku dheelitirka xoogga sare, resity-ka wanaagsan, iyo iska caabin aad u fiican. Tani waxay ka dhigeysaa inay ku habboon tahay in laga dalbado codsiyada Aerospace, gawaarida, iyo waaxaha warshadaha ay tahay in agabtualku ay tahay inay si isku mid ah ugu saadaalinayso jawiga sare iyo jawiga heerkulka-sare. , oo ay ku jiraan biyaha badda, aashitada fudud, iyo alkalis.
