Musiyano pakati peQ460NC simbi ndiro uye Q460C, ukobvu kuita kweQ460NC simbi ndiro inodarika makumi masere.
Musiyano uripo pakati peQ460NC simbi ndiro neQ460C ndewekuti ukobvu hweQ460NC simbi ndiro inodarika makumi masere, uye iyo yakajairwa inotenderedza ndiro Q460NC simbi ndiro isimbi yakaderera-yepamusoro-simba.Iyo Q mugiredhi reQ460NC inomiririra kusimba kwegoho resimbi.Mavara makuru;460 inomirira 460 MPa, mega ine gumi kusvika kune yechitanhatu simba, uye Pa ndiyo yekumanikidza unit Pascal;Q460 inoreva kuti deformation yepurasitiki ichaitika chete kana simba remagetsi resimbi rasvika 460 MPa, kureva kuti, kana simba rekunze rasunungurwa, Simbi inogona kuchengetedza chimiro chesimba uye haigoni kudzokera kune chimiro chayo chepakutanga, iyo yakasimba kudarika. simbiwo zvayo.N inomirira normalizing kana normalizing rolling, C—quality giredhi ndiC (magiredhi akakamurwa kuita C, D, E).
Kuendesa mamiriro eQ460NC simbi ndiro: normalizing, normalizing rolling
