He aha te rerekētanga i waenga i te Q195, Q215, Q235, Q255 me te Q275 e pā ana ki ngā rauemi?
Ko te maitai hanganga waro te maitai e whakamahia nuitia ana, ko te nuinga o te wā ka hurihia hei maitai, ko ngā kōtaha me ngā kōtaha te mea nui, ā, ko te tikanga kāore e hiahiatia kia whakamahanahia te tukatuka tika, ko te nuinga mō te hanganga whānui me te hangarau.
Ko te Q195, Q215, Q235, Q255 me Q275, me ētahi atu, e tohu ana i te taumata o te maitai, ko te tohu maitai mā te tohu o te pūwāhi hua o te reta (Q), te uara pūwāhi hua, te kounga, te kounga me ētahi atu tohu (A, B, C, D) tikanga tango hāora o ngā tohu me ētahi atu wāhanga e whā o te hanganga raupapa. Mai i te hanganga matū, ko ngā tohu maitai ngawari Q195, Q215, Q235, Q255 me Q275 he nui ake ngā tohu, ko te teitei ake o te ihirangi waro, te ihirangi konupora, ko te pumau ake o tōna kirihou. Mai i ngā āhuatanga miihini, ko ngā tohu i runga ake nei e tohu ana ko te matotoru o te pūwāhi hua o te maitai he ≤ 16mm. Ko tōna kaha kume ko: 315-430, 335-450, 375-500, 410-550, 490-630 (obN/mm2); Ko te roa o te qi ko: 33, 31, 26, 24, 20 (0.5%). Nō reira, i te wā e whakauru ana i te maitai ki ngā kaihoko, me whakamahara ki ngā kaihoko kia hoko i ngā rauemi maitai rerekē e ai ki ngā rauemi hua e hiahiatia ana, kia kore ai e pā ki te kounga o te hua.
He aha te rerekētanga i waenga i ngā rauemi Q235A me Q235B?
He maitai waro te Q235A me te Q235B. I roto i te paerewa ā-motu GB700-88, ko te rerekētanga o ngā rauemi Q235A me te Q235B kei roto i te nui o te waro o te maitai, ko te nui o te waro o te rauemi Q235A kei waenganui i te 0.14-0.22 ﹪; kāore te rauemi Q235B e whakamātautau pānga, engari he maha ngā wā ka whakamātautau pānga pāmahana, V-notch. Ki te whakataurite, he pai ake ngā āhuatanga miihini o te rauemi maitai Q235B i te rauemi maitai Q235A. I te nuinga o te wā, ka tohua te mira maitai i roto i ngā kōtaha kua oti i mua i te wehenga atu i te wheketere ki te pereti tautuhi. Ka taea e ngā kaiwhakamahi te kī mēnā he rauemi Q235A, Q235B, he rauemi kē atu rānei i runga i te pereti tohu.
Ko ngā momo maitai Hapanihi ko SPHC, SPHD, me ētahi atu. He aha te tikanga o ēnei?
Ko ngā momo maitai Hapanihi (raupapa JIS) o te maitai hanganga noa e toru ngā wāhanga: ko te wāhanga tuatahi e tohu ana i te rauemi, pērā i: S (Rino) te tikanga o te maitai, F (Ferrum) te tikanga o te rino. Ko te wāhanga tuarua o ngā āhua, momo, whakamahinga rerekē, pērā i P (pereti) te pereti, T (ngongo), K (kogu) te taputapu. Ko te wāhanga tuatoru o ngā āhuatanga o te ripanga o te tau, ko te nuinga o te kaha kume iti rawa. Pērā i: ss400 - ko te tuatahi s te maitai (Steel), ko te tuarua s te "hanganga" (Structureee), 400 mō te kaha raina raro o te 400Mpa maitai hanganga noa. I roto i ēnei: sphc ---- tuatahi Ssteel Steel whakarāpopototanga, P mō te pereti Pate whakarāpopototanga, H mō te whakarāpopototanga wera Weat, whakarāpopototanga arumoni, ko te katoa e tohu ana ko te whānui wera-hurihuri me te rino rīpene.
Ko te SPHD----- e tohu ana i te pepa maitai me te rīpene kua hurihia kia wera hei tā.
Ko te SPHE------ e tohu ana i ngā pepa me ngā rīpene maitai kua hurihia kia wera hei kukume hōhonu.
Ko te SPCC------ e tohu ana i te pepa me te rīpene maitai waro hurihuri matao mō te whakamahinga whānui, he rite ki te tohu Haina Q195-215A. Ko te reta tuatoru C he whakarāpopototanga mō te Matao, e hiahiatia ana hei whakarite i te whakamātautau kume i te mutunga o te tohu me te T mō te SPCCT.
Ko te SPCD------ e tohu ana i te maitai waro hurihuri matao me te rīpene maitai mō te wero, he rite ki te maitai hanganga waro kounga teitei o Haina 08AL (13237).
Ko te SPCE------ e tohu ana i te pepa maitai waro hurihuri matao me te rīpene mō te kume hohonu, he rite ki te maitai wero o Haina 08AL (5213). Hei whakarite kia kore e mahi, tāpirihia te N ki te SPCEN i te mutunga o te taumata.
He tohu mō te pepa maitai waro hurihuri matao me te rīpene, he āhua whakamahana mō A, he āhua whakamahana paerewa mō S, 1/8 mārō mō te 8, 1/4 mārō mō te 4, 1/2 mārō mō te 2.
Waehere whakaoti mata: kāore he kanapa mō te D, ā, kāore he kanapa mō te B. Pērā i te SPCCT-SD, ko te pepa waro hurihuri matao kua whakamahanahia, kāore he kanapa mō te whakamahinga whānui. Kātahi ka tohu te SPCCT-SB i te pepa waro hurihuri matao kua whakamahanahia, kua oti te whakakī kanapa, me ngā āhuatanga miihini kua whakamanahia.
