1) Chitsulo cha giya cha 42CrMo chili ndi mphamvu zambiri, kulimba kwambiri, kulimba bwino, kusintha pang'ono panthawi yozimitsa, mphamvu zambiri zoyenda komanso mphamvu yolimba pa kutentha kwambiri.

Amagwiritsidwa ntchito popanga ma forging omwe amafunikira mphamvu zambiri komanso zigawo zazikulu zozimitsidwa komanso zofewa kuposa chitsulo cha 35CrMo, monga: magiya akuluakulu ogwirira ntchito ya locomotive, magiya otumizira ma supercharger, magiya a zombo zopanikizika, ma axles akumbuyo, ndodo zolumikizira zodzaza kwambiri ndi masipure. Angagwiritsidwenso ntchito polumikiza mapaipi obowola mafuta ndi zida zosodza zosakwana 2000m; ndipo angagwiritsidwe ntchito popanga makina opindika, ndi zina zotero.

2) Chitsulo cha giya cha 20CrMnTiH ndi chitsulo chopangidwa ndi carburizing chomwe chimagwira ntchito bwino, chimalimba kwambiri, chimalimba komanso chimatha kusweka pamwamba komanso chimalimba kwambiri chikatha kusweka ndi kuzimitsidwa, chimalimba kwambiri kutentha, chimatha kusweka pang'ono, ndipo chimatha kusweka chikatha kusinthidwa.

Amagwiritsidwa ntchito popanga zigawo zofunika ndi gawo lopingasa <30mm lomwe limapirira kuthamanga kwambiri, katundu wapakati kapena wolemera, kugwedezeka ndi kukangana; monga: magiya, magiya ozungulira, mitu yopingasa ya giya, ndi zina zotero. Ndi chitsulo cholowa m'malo mwa 18CrMnTi, chomwe chimagwiritsidwa ntchito kwambiri ngati zigawo zopindika. Chimagwiritsidwa ntchito m'mafakitale a magalimoto ndi mathirakitala okhala ndi gawo lochepera 30mm; ndi gawo lofunika kwambiri lopindika lomwe limanyamula katundu wothamanga kwambiri, wapakati kapena wolemera ndipo limakhudzidwa ndi kukangana;
