ASTM A302 GR.B Mn-Mo Alloy Ipa Irin Awo

ASTM A302 boṣewa sipesifikesonu fun awọn awo titẹ ọkọ ni irin alloy, manganese molybdenum ati manganese-molybdenum-nickel.
ASTM A302 jẹ iru sipesifikesonu alloy kekere, irin ni wiwa awọn onipò 4 oriṣiriṣi (A, B, C, D), Ite C ati D ni akopọ kemikali Ni, pẹlu sisanra kanna, ikore ati agbara fifẹ ti Ite C jẹ kanna ti Ipele B, lakoko ti oṣuwọn elongation ti ite C ga julọ.
A302 ite B irin awo yoo wa ni deede pese ni bi-yiyi majemu. Awọn awo le wa ni pase tobojumu tabi wahala relieved, tabi awọn mejeeji. Ti Ite B 302 loke 50mm ni sisanra yoo jẹ deede.
