ASTM A302 GR.B Mn-Mo Alloy Umuvuduko Wicyuma Cyuma

ASTM A302 ibisobanuro byerekana ibyombo byumuvuduko mubyuma bivanze, manganese molybdenum na manganese-molybdenum-nikel.
ASTM A302 ni ubwoko bwicyuma giciriritse cyicyuma gikubiyemo ibyiciro 4 bitandukanye (A, B, C, D), Icyiciro C na D kirimo imiti Ni, hamwe nubunini bumwe, umusaruro hamwe nimbaraga zingana za Grade C ni kimwe na Grade B, mugihe igipimo cyo kurambura icyiciro C kiri hejuru.
Icyapa cya A302 Icyiciro cya B gisanzwe gitangwa muburyo buzunguruka. Isahani irashobora gutegekwa mubisanzwe cyangwa guhangayika, cyangwa byombi. Niba A 302 Icyiciro B kiri hejuru ya 50mm mubyimbye bizaba bisanzwe.
