9 nga rauemi cr2mo mo te maitai Cr2 matao roera angamaheni kei roto i te ahumahi e whakamahia ana i roto i te hanga o te matao hurihuri me te roera o te roera o te mate matao me te kuia me etahi atu mea hanga engari he maha nga mea kaore e mohio mo te 9 cr2mo tikanga maimoatanga wera, na konei ko te nuinga. ki te korero mo te 9 cr2mo tikanga maimoatanga wera, tumanako ki te kia o spheroidizing annealing: 1 790 ~ 810 whakawera, waiariki, 650 ~ 670, 500 mai i te whakamahana hau;2 tinei: te wera whakamahana = 880~900, te whakamahana whakamahana: kia rite ki nga rereke rereke me nga whakaritenga rereke, ka taea te whakamahi i te reo whakamahana penei i te wai PAG tinei hinu wai.
Panui: Ko nga whao he maitai Cr2 cold roll.
