He aha te rerekētanga i waenganui i te Q235 me te SS400?

Ko te Q235 me te SS400 he maitai hanganga waro e whakamahia whānuitia ana, e kiia ana he rite tonu te mahi, engari i ahu mai i ngā paerewa ā-motu rerekē, ā, he iti noa ngā rerekētanga o te hanganga matū me ngā āhuatanga miihini. Ko te Q235 e tautuhia ana i raro i te paerewa GB/T 700 o Haina, ko te SS400 ia kei raro i te paerewa JIS G3101 o Hapani. Ahakoa ō rāua takenga mai rerekē, he maha tonu te whakamahinga i roto i ngā tono hanganga rite pērā i ngā piriti, ngā whare, me ngā wāhanga mīhini.

I runga i te āhua matū, he rino waro-iti te Q235 me te SS400, he mea hanga te nuinga ki te rino me te iti o te waro, te konupūmā, te whākōkī, me te whanariki. Ko te nui rawa o te waro o te Q235 he 0.22%, ā, he tino kaha ngā herenga mō ētahi atu huānga kia pai ake ai te whakarewa me te ngāwari. He rite te hanganga o te SS400 engari he paku ngāwari ake ētahi huānga i runga i te tukanga hanga. He iti noa iho ēnei rerekētanga, engari i roto i ētahi tono—ina koa ko ngā mea e whai ana i ngā whakaritenga whakarewa tika, i te tiwhikete rauemi ā-ao rānei—tērā pea he mea nui.

I roto i te hangarau, i tapaina te Q235 i muri i tōna kaha tuku o te 235 MPa, ko te SS400 ia he kaha tuku rite o te 245 MPa. He rite tonu te awhe o ō rāua kaha kume, i waenga i te 375 ki te 500 MPa. Nō reira, ka taea e ngā maitai e rua te mahi pai i roto i ngā tono hanganga, ā, he maha ngā wā ka whakamahia ngātahitia ina whakaaetia e ngā paerewa ā-rohe. Heoi, he mea nui kia mōhiotia me whakaaetia tonutia ngā whakakapinga rauemi e ngā miihini hanganga, e ngā mana hoahoa rānei, inā koa i roto i ngā kaupapa kua whakaritea, i ngā kaupapa haumaru rānei.

Mō te whakamahinga, ko te Q235 te mea e kitea whānuitia ana i te mākete o Haina, ā, he maha ngā wā ka whiriwhiria mō te hanga me te hanga whānui he iti te utu. Ko te SS400, he paerewa Hapanihi, e whakamahia whānuitia ana i Hapani me ētahi atu wāhi o Āhia. Ina uru atu ki te hokohoko o te ao, ko te kōwhiringa i waenga i te Q235 me te SS400 ka whakawhirinaki pea ki te wātea o te mekameka tuku, ngā whakaritenga tiwhikete, me ngā manakohanga a te kiritaki. Hei whakamutunga, ahakoa he rite tonu te Q235 me te SS400 i roto i ngā āhuatanga maha, mā te mōhio ki ō rāua rerekētanga ngawari ka pai ake te whakatau i te kōwhiringa rauemi.
