9 cr2mo mea mo masani Cr2 cold roll uʻamea e masani lava i le alamanuia faʻaaogaina i le gaosiga o le malulu taʻavale ma le roller of cold die ma punch etc forging ae toʻatele e fai mai e le iloa e uiga i le 9 cr2mo togafitiga vevela, o lea e masani lava. e talanoa e uiga i 9 cr2mo auala vevela togafitiga, faamoemoe o le spheroidizing annealing: 1 790 ~ 810 faamafanafanaina, isothermal, 650 ~ 670, 500 mai ea cooling;2 tineia: vevela vevela = 880 ~ 900, tinei cooling: e tusa ai ma forgings eseese ma manaoga eseese, cooling medium e pei o le vai PAG tineia suauʻu suauʻu e mafai ona faʻaaogaina.
Fa'aaliga: O fa'ailoga e masani ai Cr2 cold roll sila.
