Whakatakotoranga whakaputa:

Te diameter o waho o te paipa maitai 20-426

Steel putorino taiepa matotoru o 20-426

Hua whakataki:

Ko te kaupapa o te paipa maitai 42crmo: ko te maitai motuhake mo te piriti ko "42crmo", ko te maitai motuhake mo te whitiki motuka ko "42CRmo", ko te maitai motuhake mo te ipu pehanga ko "42Crmo".Ko tenei ahua o te maitai ko te whakawhirinaki ki te whakarereketanga o te waro (C) ihirangi ki te whakapai ake i nga taonga miihini o te maitai, na reira, i runga i te ihirangi waro o te teitei me te iti, ka taea te wehewehe i tenei momo maitai ki: iti waro maitai - waro Ko te ihirangi he iti iho i te 0.25%, penei i te 10, 20 te maitai, me etahi atu;Wao waro maitai – te nuinga o te waro kei waenga i te 0.25 ~ 0.60%, penei i te 35, 45 te maitai, me etahi atu. Te waro maitai teitei – te nui o te waro i te 0.60%.Ko te tikanga karekau taua maitai e whakamahia hei hanga paipa maitai.
