Ko te pae rino waro he pae rino roa, papatahi, tapawhā rite, e hangaia ana mā te huri wera, mā te kume makariri rānei. He nui ake tōna whānui i tōna matotoru, e wehewehe ana i a ia mai i ngā pae tapawhā, porowhita rānei. Ko te kupu "rino waro" e tohu ana ko tōna huānga matua he waro, he iti noa iho ngā huānga kē atu pērā i te konupūmā, te silicon, me te whanariki kei roto. Ko te nui o te waro (mai i te 0.05% ki te neke atu i te 1.0%) ka pā tika ki te pakeke, te kaha, te ngāwari, me te kaha whakarewa o te pae rino.
Ko te hurihuri matao he hurihuri e mahia ana i raro i te pāmahana whakakōkī anō. I te nuinga o te wā ka mahia i te pāmahana rūma, ahakoa i ētahi wā ka whakamahanahia te maitai kia iti ake te uaua o te tukatuka, engari he iti iho te pāmahana i te pāmahana hurihuri wera.
Ko te hurihuri makariri te tikanga e mahia ana i runga i te maitai hurihuri wera. Whai muri i ngā maimoatanga mata pēnei i te whakapūkara, ka whāngaihia te maitai hurihuri wera ki roto i te mira hurihuri makariri hei hurihuri tonu. I te wā hurihuri makariri, ka whakaitihia te matotoru o te maitai, ā, ka whakapaitia tōna tika o ngā āhuatanga me te kounga o te mata mā te mahi pēhi o ngā roera i te pāmahana rūma. Nā te mea ka mahia te hurihuri makariri i ngā pāmahana iti iho, ka kitea te whakapakeketanga mahi o te maitai, me te hiahia kia whakamahanahia waenga me ētahi atu maimoatanga hei whakahoki mai i tōna kirihou. Whai muri i te whakapakeketanga mahi, ka nui ake te kaha o te maitai hurihuri makariri, engari ka iti haere tōna kirihou me tōna pakari. Ka tukuna e te maitai hurihuri makariri he kounga mata teitei ake me te tika o ngā āhuatanga, kia pai ai mō ngā tono e hiahia ana ki te kounga mata teitei me te tika o ngā āhuatanga.
Ko te hurihuri wera he tukanga hurihuri e mahia ana i runga ake i te pāmahana whakahou-whakakiriata. Ko te nuinga o ngā pae papatahi maitai waro ka hangaia mā te hurihuri wera. Ko te pāmahana whakamahana i te nuinga o te wā kei te 1100℃ ki te 1250℃, ā, i taua wā ka noho te maitai i roto i te āhua whakangawari pāmahana teitei, ka ngāwari te whakapohehe kirihou. He ohanga ēnei, e wātea ana i roto i te whānuitanga o ngā rahi, mai i te 1/8 inihi ki te 4 inihi te matotoru me te 12 inihi te whānui.
Tuatahi, ka whakamahanahia te pereki maitai ki te pāmahana teitei, kātahi ka hurihia kia maha ngā wā i roto i tētahi raupapa o ngā rōra, ka whakaiti haere i te matotoru o te maitai me te whakarerekē i tōna āhua me ngā rahi. I te wā e hurihia ana te maitai wera, ka huri te hanganga iti o te maitai; ka hurihia te hanganga whakarewa taketake hei hanganga hurihia wera-aronga mā te hurihuri me te whakamatao. Ko te mata o te maitai hurihia wera he taratara ake, ā, tera pea he putunga pēnei i te unahi waikura rino. He iti ake te kaha o te maitai hurihia wera engari he pai ake te kirihou me te pakari. Nā te mea ka wera te maitai i te pāmahana teitei me te whakamatao tere i te wā e hurihia ana te maitai, ka hua ake he hanganga iti ōrite ake, ā, he iti ake te ahotea o roto.
Ko ngā āhuatanga ā-pūkaha o ngā pae papatahi maitai waro e whakawhirinaki ana ki te nui o te waro me te tukanga tukatuka wera. Ko te kaha kume o ngā pae papatahi maitai waro-iti noa (AISI 1018, ASTM A36) he tata ki te 400–550 MPa te kaha kume, tata ki te 250–350 MPa te kaha hua, ā, ko te roa i te whati he 20–25%. He ngohengohe, he ngāwari te whakarewa, ā, he ngāwari ki te whakarewa, ki te mīhini rānei. I muri i te whakataurite, ka taea e te maitai waro-waenga (AISI 1045 te whakatutuki i te kaha kume o te 570–700 MPa, engari ka heke tōna kaha whakarewa. Ka taea e te maitai waro-nui (AISI 1095) te neke atu i te 800 MPa te kaha kume, engari ka pakarukaru mēnā kāore i tukatukahia ki te wera.
Haunga te waro, he iti noa iho ngā mahi a ētahi atu huānga. Ka whakanui ake te konupora (tae atu ki te 1.65%) i te kaha, ā, ka tangohia ngā waikura mai i te maitai. Ka puritia kia iti te nui o te whākawa me te whanariki (kei raro iho i te 0.05%) hei ārai i te pakarukaru makariri me te pakaru wera. Ka tukuna ētahi maitai papatahi ki te tukanga whakapūkara me te hinu hei tango i te unahi hurihuri me te whakarato i te tiaki waikura rangitahi.
Ko tētahi o ngā wāhi matua e whakamahia ana mō te maitai waro papatahi ko te umanga hanga. He maha ngā wā ka whakamahia ēnei maitai papatahi hei wāhanga hanganga i roto i ngā whare, i ngā piriti, me ētahi atu kaupapa hanganga. Nā tō rātou kaha me tō rātou pakari ka pai mō te tautoko i ngā kawenga taumaha me te whakarato i te pumau mō ngā momo hanganga. Hei tāpiri, he maha ngā wā ka whakamahia te maitai waro papatahi hei hanga anga, tautoko, me ngā whāriki; nā tōna āhua papatahi ka taea te whakauru ki ngā momo hoahoa. Nā te maha o ngā whakamahinga o ngā hua maitai papatahi ka pai ake ai rātou mō ngā miihini me ngā kaihoahoa.
Haunga te umanga hanga, he whānuitia hoki ngā whakamahinga o te rino waro papatahi i roto i ngā umanga motuka me ngā mīhini. He mea whakamahi noa ēnei i roto i te hanga o ngā wāhanga motuka, pērā i te chassis, te toki, me ngā pūnaha whakatārewatanga. Nā te ōwehenga kaha-ki-taumaha teitei o te rino waro papatahi ka taea e ngā kaihanga te hanga i ngā wāhanga mama engari pakari, ā, ka whakapai ake i te mahi a te waka me te whai huatanga o te wahie. Hei tāpiri, i roto i te umanga mīhini, ka whakamahia ngā hua rino papatahi hei hanga taputapu me ngā taputapu, ā, he mea nui te roa me te ātete ki te kakahu mō te mahi roa.
Ko te whiriwhiri i te pae papatahi maitai waro tika me taurite i ētahi āhuatanga: ngā āhuatanga miihini e hiahiatia ana (kaha, ngāwari, pakeke), te tika o ngā āhuatanga, te mutunga o te mata, ngā taiao waikura, ngā tikanga tukatuka (whakapiri, mīhini, piko), me ngā here tahua. Mō te nuinga o ngā tono hanganga whānui, ko te pae papatahi maitai waro-iti ASTM A36 te huinga pai rawa atu e pā ana ki te wātea, te ngāwari ki te mīhini, me te utu. Mō ngā rakau tino tika, mō ngā ara ārahi taputapu mīhini rānei, he pai ake te whiriwhiri i te maitai 1018, 1045 rānei e tōia ana i te makariri. Mō ngā wāhanga kua pakaru rawa pērā i ngā waru, me whakamahi pea i te maitai waro-nui, i te pae papatahi rānei kua whakamahanatia.
