GB/T5310-2008ngongo maitai tui ko te ahua o te ngongo maitai kounga teitei.Kua wehea te ngongo kohu ki te ngongo kohua whanui me te ngongo kohu pehanga teitei kia rite ki tana mahi pāmahana teitei.Ko te nuinga o te putorino putorino pehanga teitei e whakamahia ana mo te hanga pehanga teitei me runga ake i te pehanga kohu korohu, putorino me etahi atu waro hanganga maitai o te kounga teitei, koranu te hanga maitai me te kowiri tira wera kowiri tira putorino maitai.[1] Ko enei ngongo paoho e mahi ana i te teitei o te pāmahana me te pehanga, ka whakaputa i te hau rewharewha teitei me te kohu wai, he pai ki te waikura me te waikura.

Te karaehe maitai

(1) Te kounga teitei o te waro hanganga maitai maitai 20G, 20MnG, 25MnG. 

(2) Te maitai o te hanganga Alloy 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc. 

(3) Waikura wera wera rino e whakamahia nuitia ana 1Cr18Ni9, 1Cr18Ni11Nb ngongo kōhua ​​i tua atu ki te whakarite hanganga matū me ngā āhuatanga pūkaha, ki te mahi whakamātautau pēhanga wai, ki te hanga mura, whakamātautau kōpeketanga.Ko nga ngongo maitai ka tukuna i roto i nga ahuatanga maimoatanga wera. 

Hei taapiri, ko te microstructure, te rahi o te witi me te paparanga decarburization o nga ngongo maitai kua oti e hiahiatia ana.

I tua atu ki te pehanga teitei kōhua ​​ngongo maitai tuiGB/T5310-2008kua whakahuahia i runga ake nei, ko nga hua matua o ta maatau kamupene ko:
