(Mehemea he rite, nui ake ranei te horahanga i te 0.75 in.2 (500 mm2), katahi ka whakamahia te uara 0.75 in.2 (500 mm2). U = te kaha tensile kua tohua, psi (MPa). |
Whakaritenga Whakamatau
Hei taapiri atu ki te whakarite i te hanganga matū me nga taonga miihini, ka mahia nga whakamatautau hydrostatic takitahi, ka mahia nga whakamatautau mura me te papatahi. . I tua atu, kei reira etahi whakaritenga mo te microstructure, te rahi o te witi, me te paparanga decarburization o te paipa maitai oti.
