(1)Nzira yekunyungudutsa simbi
GB 5310 20MnG simbi ichanyungudutswa nechoto chemagetsi pamwe nekunatsa muchoto, okisijeni inoshandura pamwe nekunatsa muchoto kana electroslag remelting nzira.
(2) Nzira dzekugadzira uye zvinodiwa kune chubhu blanks
Iyo chubhu isina chinhu inogona kugadzirwa nekuramba ichikandira, kufa kukandira kana kupisa kukungurukira (forging).
(3)Kugadzira nzira yesimbi chubhu
GB 5310 20MnG Simbi machubhu anozogadzirwa nekupisa kutenderedza (extrusion, kuwedzera) kana kutonhora kudhirowa (kukunguruka).
