Ko te A335 P22 he 2.25Cr-1Mo Chromium-molybdenum teitei Temperature ferritic maitai mo nga kohu me nga wera nui,ASTM A335/A335Mpaerewa. I te tau 1985, i whakawhitia ki GB5310 ka whakaingoatia ko 12Cr2MoG. Ko etahi atu whenua he rite nga tohu rino, penei i te Federal Republic of Germany 10CrMo910 me Japan STBA24. I roto i nga raupapa rino cr-1Mo, he teitei te kaha o te waiariki, i raro i te pāmahana kotahi (te wera≤580℃) tona kaha whati wiri me te ahotea whakaaetia he teitei ake i te 9CR-1Mo maitai, a he pai te mahi tukatuka me te mahi fehokotaki'anga, pai kirihou roa. Na reira, kua whakamahia nuitia i roto i te taiao mahi kino, penei i te hiko waiariki, te hiko karihi me etahi taputapu hauwai i roto i nga momo paipa whakawera me nga oko pehanga teitei.
Te pāmahana e whakaaetia ana: A335P22 (SA-213T22) kei te nuinga o te waa e whakamahia ana i roto i te 300,600MW me etahi atu kaha nui te kaha o te kaha o te kaha o te kaha o te kaha o te kaha o te kaha o te wera o te taiepa.≤580℃whakawera teitei me te pāmahana pakitara ngongo & LT;540℃taiepa mamaoa paipa me te pane, kua whakamahia whānuitia tenei ahua o te maitai i roto i te United States, Japan me Europe, he hītori roa o te mahi i roto i te tipu hiko, he mahi pūmau, mahi tukanga pai o te maitai pakeke.
12Cr1MoV maitai no te chromium-molybdenum vanadium maitai vanadium maitai, te nuinga whakamahia mo 12Cr1MoV/GB5310 paipa maitai. Ka whakamahia whānuitia, ko te pāmahana i roto i te 480℃~580℃rohe pāmahana teitei me tetahi o nga rawa rawa. 12Cr1MoVG te pāmahana ratonga ngongo maitai: te nuinga whakamahia mo te maitai matua o te ngongo superheater, pane me te putorino mamaoa o te pehanga teitei kōhua he iti iho te pāmahana pakitara ngongo ki te 580 ranei.℃.
