Mapepala a nyundo a zipangizo zophwanyira crusher pansi pa kuzungulira kwachangu, motero amakhala ndi mphamvu ya zipangizo. Zipangizo zomwe ziyenera kuphwanyidwa ndi zolimba kwambiri monga chitsulo ndi miyala, kotero mapepala a nyundo amafunika kukhala olimba mokwanira. Malinga ndi deta yofunikira yaukadaulo, pokhapokha ngati kuuma ndi mphamvu ya zinthuzo kufika pa HRC>45 ndi α>20 J/cm² motsatana, ndi pomwe zofunikira pakugwira ntchito pansi pa mikhalidwe yogwirira ntchito yomwe ili pamwambapa zingakwaniritsidwe.
Kutengera ndi makhalidwe ogwirira ntchito ndi zofunikira za mbale za nyundo, zipangizo zomwe zimagwiritsidwa ntchito kwambiri ndi chitsulo cha manganese chochuluka ndi chitsulo chocheperako chomwe sichingawonongeke ndi aloyi. Chitsulo cha manganese chochuluka chimakhala ndi kukana bwino kuvulala komanso kulimba kwambiri. Pambuyo pozimitsa + kutentha pang'ono, chitsulo chocheperako chomwe sichingawonongeke ndi aloyi chimapanga kapangidwe ka martensite kolimba komanso kolimba, komwe kumawongolera kuuma kwa aloyi pomwe kumasunga kulimba bwino. Zipangizo zonsezi zimatha kukwaniritsa zofunikira zogwirira ntchito za mbale za nyundo.
