9 cr2mo mea mo masani Cr2 cold roll uʻamea e masani lava i le alamanuia faʻaaogaina i le gaosiga o le malulu taʻavale faʻatasi 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 le 9 cr2mo auala togafitiga vevela, faʻamoemoe o le spheroidizing annealing: 1 790 ~ 810 faʻamafanafanaina, isothermal, 650 ~ 670, 500 mai ea cooling;2 tineia: vevela vevela = 880 ~ 900, quenching cooling: e tusa ai ma forgings eseese ma manaoga eseese, cooling ala 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.

3 Mata'utia tulaga vevela (tulaga tau):Ac1 =740 C Ar1 =700 C Accm:850 C 4 Fa'amatalaga Fa'amalulu masani mo avanoa malulu oomi820 10) C 3 ~ 4h, faatasi ai ma le fua faatatau mālūlū o.15 C / h, faatasi ai ma le ogaumu maalili lemu i le 650 C, 5 malulu oomi avanoa mai le ogaumu malulu i spindle-spindled faamaluluina specifications820 10) C 3 ~ 4h, (720 10) C 6 ~ 8h, ona faʻafefeteina ai lea o le ogaumu i le 600 C, Faʻamatalaga mo le faʻavasegaina: normalizing vevela 900 ~ 920 C, maaa 302-388HBW 7 Batch isothermal spheroidizing ~ Annealing :790 810 C 2 ~ 3h, fa'alili ogaumu, 7O0-720 C 3 ~ 4h, maaa 217HBW, Pearlitic tissue vasega 2-5, Faʻamatalaga mo le tineia ma le faʻafefeteina o 8 faʻamaʻiina o mata carbide vasega 2 1. Quenching vevela 830-850 C, maaa 62-65 HRC, vevela vevela 130- 150 C, malo 62-65 HRC 2. Quenching vevela 840-860 C, maaa 61-63 HRC, vevela vevela 150-170 C, maaa 60-62HRC.
