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

ASTM A302 paerewa paerewa mo nga pereti oko pehanga i roto i te rino koranu, manganese molybdenum me te manganese-molybdenum-nickel.
Ko te ASTM A302 he momo whakahiato rino koranu iti e hipoki ana i nga tohu rereke e 4 (A, B, C, D), Ko te Koeke C me D kei roto i te hanganga matū Ni, he rite te matotoru, te tuku me te kaha o te Tohu C he rite tonu ki te Tohu. B, i te mea he teitei ake te reiti whakaroa o te kōeke C.
Ko te pereti rino A302 Koeke B ka tukuna i roto i te ahua kua hurihia. Ka tonohia nga pereti kia rite, kia marie ranei te ahotea, e rua ranei. Mena he A 302 Koeke B kei runga ake i te 50mm te matotoru ka whakatauritea.
