SS400He pereti maitai hanganga waro paerewa Hapanihi tēnei e rite ana ki te JIS G3101. E rite ana ki te Q235B i roto i te paerewa ā-motu o Haina, me te kaha kume o te 400 MPa. Nā te nui o te waro, he pai te taurite o ngā āhuatanga whānui, e tutuki ai te taurite pai i waenga i te kaha, te ngāwari, me te kaha whakarewa, koia te momo e whakamahia whānuitia ana.
Ngā rerekētanga i waenga iQ235b Ss400:
Ngā Paerewa Rerekē:
Q235BE whai ana te "Q" i te Paerewa ā-Motu o Haina (GB/T700-2006). Ko te "Q" te tohu o te kaha hua, ko te '235' te tohu o te kaha hua iti rawa o te 235 MPa, ā, ko te "B" te tohu o te kounga. E whai ana te SS400 i te Paerewa Ahumahi Hapanihi (JIS G3101), ko te "SS" te tohu o te maitai hanganga, ā, ko te "400" te tohu o te kaha kume neke atu i te 400 MPa. I roto i ngā tauira pereti maitai 16mm, he 10 MPa teitei ake te kaha hua o te SS400 i te Q235A. Ko te kaha kume me te roa e nui ake ana i te Q235A.
Ngā Āhuatanga Mahi:
I roto i ngā mahi whaihua, he rite tonu te mahi a ngā momo e rua, ā, he maha ngā wā ka hokona, ka tukatukahia hoki hei maitai waro noa, engari kāore i te tino kitea ngā rerekētanga. Heoi, mai i te tirohanga whakamāramatanga paerewa, ka aro nui a Q235B ki te kaha tuku, ko SS400 ia ka aro nui ki te kaha kume. Mō ngā kaupapa he whakaritenga taipitopito mō ngā āhuatanga miihini o te maitai, me hangai te kōwhiringa ki ngā hiahia motuhake.
He whāiti ake te whānuitanga o te whakamahinga o ngā pereti maitai Q235A i te SS400. He rite tonu te SS400 ki te Q235 o Haina (he rite ki te whakamahinga o te Q235A). Heoi, he rerekē ngā tohu motuhake: e tohu ana te Q235 i ngā rohe ihirangi mō ngā huānga pēnei i te C, Si, Mn, S, me te P, ko te SS400 ia e hiahia ana kia iti iho i te 0.050 te S me te P. Ko te kaha whakaputa o te Q235 e neke atu ana i te 235 MPa, ko te SS400 ia e eke ana ki te 245 MPa. Ko te SS400 (te maitai mō te hanganga whānui) e tohu ana i te maitai hanganga whānui me te kaha kume e neke atu ana i te 400 MPa. Ko te Q235 e tohu ana i te maitai hanganga waro noa me te kaha whakaputa e neke atu ana i te 235 MPa.
Ngā Whakamahinga o te SS400: He mea hanga noa te SS400 hei rakau waea, hei pae porowhita, hei pae tapawhā, hei pae papatahi, hei pae koki, hei kurupae-I, hei wāhanga awaawa, hei maitai anga matapihi, me ētahi atu āhua hanganga, tae atu ki ngā pereti matotoru-waenga. He whānuitia te whakamahinga i roto i ngā piriti, kaipuke, waka, whare, me ngā hanganga hangarau. He pai hei pae whakapakari, hei hanga rānei i ngā tuanui wheketere, i ngā pourewa tuku hiko-tiketike, i ngā piriti, i ngā waka, i ngā kohua, i ngā ipu, i ngā kaipuke, me ētahi atu. He whānuitia hoki te whakamahinga mō ngā wāhanga miihini me ngā whakaritenga mahi iti ake te kaha. Ka taea hoki te whakamahi i ngā maitai Reanga C me D mō ētahi whakamahinga motuhake.
