ASTM A302 GR.B Mn-Mo Alloy Pressure Vessel Steel Plate

ASTM A302 muyezo specifications mbale kuthamanga chotengera mu aloyi zitsulo, manganese molybdenum ndi manganese-molybdenum-nickel.
ASTM A302 ndi mtundu wa otsika aloyi zitsulo specifications chimakwirira 4 giredi (A, B, C, D), Grade C ndi D lili mankhwala zikuchokera Ni, ndi makulidwe ofanana, zokolola ndi matenthedwe mphamvu ya kalasi C ndi chimodzimodzi kalasi. B, pomwe kuchuluka kwa giredi C ndikokwera.
Chitsulo chachitsulo cha A302 Grade B chimaperekedwa nthawi zambiri ngati chikakulungidwa. Mambale amatha kuyitanidwa kuti akhale okhazikika kapena kupsinjika, kapena zonse ziwiri. Ngati A 302 Grade B pamwamba pa 50mm mu makulidwe adzakhala normalized.
Supplementary Technology:   Mayeso a HIC | NACE MR0175 | z15 | pa z25 | pa z35 |

makulidwe: 6mm mpaka 300MM,
m'lifupi: 1500mm kuti 4050mm,
Utali: 3000mm kuti 15000mm
