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 e pā ana ki te 9 cr2mo tikanga maimoatanga wera, tumanako ki te kia o spheroidizing annealing: 1 790 ~ 810 whakawera, isothermal, 650 ~ 670, 500 i te rangi mātao;2 tinei: pāmahana whakawera = 880 ~ 900, 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 hinu.
Panui: Ko nga whao he maitai Cr2 cold roll.
