(1)Njira yosungunula zitsulo
Chitsulo cha GB 5310 20MnG chidzasungunuka ndi ng'anjo yamagetsi kuphatikiza kuyeretsa ng'anjo, chosinthira okosijeni kuphatikiza kuyeretsa ng'anjo kapena njira ya electroslag remelting.
(2) Njira zopangira ndi zofunikira pazosowa za chubu
Chubu chopanda kanthu chimatha kupangidwa ndikuponyedwa mosalekeza, kuponyera kufa kapena kugudubuza kotentha (kufota).
(3) Kupanga njira yachitsulo chubu
Machubu achitsulo a GB 5310 20MnG adzapangidwa ndi kugudubuza kotentha (kutulutsa, kukulitsa) kapena kujambula kozizira (kugudubuza).
