Iwhakauru:
I roto i te ao hanga maitai, e rua ngā momo e tū motuhake ana – ko te S275JR me te S355JR. E rua ngā momo e whai pānga ana ki te paerewa EN10025-2, ā, e whakamahia whānuitia ana i roto i ngā momo ahumahi. Ahakoa he rite te ahua o ō rāua ingoa, he āhuatanga motuhake ō ēnei momo e wehewehe ana i a rāua. I roto i tēnei tuhinga, ka rukuhia e mātou ō rāua rerekētanga me ō rāua āhua rite, me te tirotiro i te hanganga matū, ngā āhuatanga miihini, me ngā āhua hua.
Ngā rerekētanga o te hanganga matū:
Tuatahi, me aro tātou ki ngā rerekētanga o te hanganga matū. Ko te S275JR he maitai waro, ko te S355JR ia he maitai koranu iti. Kei roto i ō rātou huānga taketake tēnei rerekētanga. Kei roto i te maitai waro te rino me te waro, me te iti ake o ētahi atu huānga. I tētahi atu taha, ko ngā maitai koranu iti, pērā i te S355JR, kei roto ngā huānga koranu tāpiri pērā i te manganese, te silicon, me te phosphorus, e whakarei ake ana i ō rātou āhuatanga.
Te whanonga ā-mīhini:
Mō ngā āhuatanga ā-pūkaha, he rerekētanga nui ngā āhuatanga o te S275JR me te S355JR. Ko te kaha whakaputa iti rawa o te S275JR he 275MPa, ko te S355JR ia he 355MPa. Nā tēnei rerekētanga kaha ka pai te S355JR mō ngā tono hanganga e hiahia ana kia kaha ake hei tu atu i ngā kawenga taumaha. Heoi, me mōhio ko te kaha kume o te S355JR he iti iho i te S275JR.
Āhua hua:
Mai i te tirohanga o te āhua o te hua, he rite te S275JR ki te S355JR. E whakamahia ana ngā momo e rua i roto i te hanga i ngā hua papatahi me ngā hua roa pērā i ngā pereti maitai me ngā paipa maitai. He maha ngā whakamahinga o ēnei hua i roto i ngā ahumahi mai i te hanga ki te mīhini. Hei tāpiri, ka taea te tukatuka anō i ngā hua haurua-oti i hangaia mai i te maitai kounga teitei kore-whakarewa kua hurihia weratia hei momo hua kua oti.
Paerewa EN10025-2:
Hei whakarato i tētahi horopaki whānui ake, me matapaki tātou i te paerewa EN10025-2 e pā ana ki te S275JR me te S355JR. E whakamārama ana tēnei Paerewa Pākehā i ngā tikanga tuku hangarau mō ngā hua papatahi me ngā hua roa, tae atu ki ngā pereti me ngā ngongo. Kei roto hoki ngā hua haurua-oti ka tukatukahia anō. Mā tēnei paerewa ka whakarite kia rite te kounga puta noa i ngā momo me ngā kounga rerekē o te maitai kore-koranu kua hurihia wera.
Ngā āhuatanga ōrite o S275JR me S355JR:
Ahakoa ō rāua rerekētanga, he rite tonu ētahi āhuatanga o te S275JR me te S355JR. E tutuki ana ngā taumata e rua i ngā paerewa EN10025-2, e whakaatu ana i tō rāua piripono ki ngā tikanga whakahaere kounga tino pakari. Hei tāpiri, he whānuitia ā rāua whakamahinga i roto i ngā momo ahumahi nā ō rāua āhuatanga pai, tae atu ki te pai o te whakarewa me te tukatuka. Hei tāpiri, he whiringa rongonui ngā taumata e rua mō te maitai hanganga, ā, ka taea e rāua te tuku i ō rāua ake painga i runga i ngā whakaritenga motuhake.
