He maha ngā āhua me ngā paerewa e hangaia ana ngā tīwiri ahumahi. He tino kaha te kaha o ngā koranu rino ki te whakatārewa i ngā ahotea tino teitei i raro i te mana o te maimoatanga wera, ā, nā reira i whiriwhiria ai tēnei koranu i te wā e hangaia ana ngā pūtu rino e whakamahia ana i roto i ngā hanganga ahumahi. He teitei te ihirangi waro o ngā rino Ferroalloy, ā, he nui ake ngā āhuatanga i te rino parakore, he tino ngohengohe. Heoi anō, hei tāpiri atu ki te waro, kei roto i ngā koranu rino ngā matū whakau pēnei i te manganese, te silicon, te whanariki, te phosphorus, ā, i ētahi wā ko te vanadium (ka tāpirihia te vanadium ki ngā matū rino e hiahia ana ki te ngāwari).
I roto i te umanga hanga, he nui te whakamahinga o ngā pūtu me ngā nati hanganga i roto i te hanga whare pupuri, piriti, tāke me ngā tipu hiko. Inaa, ko te whakamahinga o ngā pūtu me ngā nati hanganga ka mahia i roto i ngā wā kotahi mā te whakarewa i ngā konganuku, arā, ko ngā pūtu hanganga, ko te whakarewa pewa rānei mā te whakamahi i ngā irahiko, i runga i te hiahia kia honoa te pereti maitai me te kurupae. He painga me he ngoikoretanga o ia tikanga hononga, ka tirohia e tātou i raro nei.
Ko ngā tīwiri hanganga e whakamahia ana i roto i ngā hononga kurupae whare he mea hanga ki te maitai kounga teitei, ko te nuinga he maitai kounga 10.9. Ko te tikanga o te kounga 10.9 ko te kaha kume o te tīwiri hanganga he tata ki te 1040 N/mm2, ā, ka taea e ia te tu atu ki te 90% o te ahotea katoa e pā ana ki te tinana tīwiri i roto i te rohe pīngore me te kore e huri āhua tuturu. Ki te whakatauritea ki te rino 4.8, te rino 5.6, te maitai maroke 8.8, he kaha kume ake ngā tīwiri hanganga, ā, he uaua ake te tukatuka wera i roto i te hanga.
He rerekē i ngā pūtu me ngā nati hexagonal paerewa, ka hangaia ngā pūtu me ngā nati hexagonal paerewa kia rite ki te paerewa DIN931 hei haurua taputapu, kia rite ki te paerewa DIN933 hei taputapu katoa, ā, he māmā ngā tīwiri hexagonal, e hangaia ana kia rite ki te paerewa DIN6914. He nui ake te kikokiko me te teitei o ngā nati hononga i runga i ngā tīwiri hanganga i ngā nati hex paerewa i hangaia ki te DIN934, e whakaatu ana i te ātete ahotea teitei ake, i hangaia ki te DIN6915. Ko ngā tīwiri o tēnei hanganga he tohu 10HV, ā, he pango matte te nuinga o te wā he phosphating pango hei whakapai ake i te ātete waikura taiao, he konukōre wera wera rānei, he hiriwa matte chrome hohonu rānei, he mea whakarewa te āhua o ēnei e rua. Ka whakamahia ēnei ki te konutea, ā, he pai te ātete taiao.
