OD: 20-660mm WT: 2.3-100mm L: 5.8M, 6M, 11.8M, 12M ranei tetahi atu roa kua tohua.

Taupānga: Hangaia, Hangarau Whānui, ringa warou, Ngaherehere, He rereke nga Porotakaro, Nga Roera Kaikawe, Nga Waahi Hollow, Nga Waahi Hollow me nga waahanga, Nati, Mowhiti, aha atu

Te whakamahi i te putorino tuitui 42CrMo: ko te maitai motuhake e whakamahia ana mo nga piriti ko "42CrMo", ko te maitai motuhake mo nga whitiki motuka ko "42CrMo", me te maitai motuhake mo nga oko pehanga ko "42CrMo".Ko tenei momo rino ka whakapai ake i nga ahuatanga miihini o te maitai ma te whakatikatika i te waro (c) ihirangi.Na reira, kia rite ki te ihirangi waro, ka taea te wehea tenei momo maitai ki: iti waro maitai - te ihirangi waro ko te tikanga iti iho i te 0.25%, pērā i te 10 me te 20 maitai;Wao waro waro - te tikanga kei waenganui i te 0.25 me te 0.60% te ihirangi waro, penei i te 35 me te 45 te maitai;Te waro maitai teitei — te nuinga o te waro he nui ake i te 0.60%.Ko tenei momo maitai kaore i te whakamahia hei hanga paipa maitai.

Taupānga Angamaheni
He pai mo te hanga i nga miihini kirihou nui me te reo-rahi e hiahia ana kia kaha me te uaua.
