Ubwino waukulu wa mankhwala a Q450NQR1 zitsulo ndikuti amapangidwa ndi chitsulo wamba wa kaboni ndipo amakhala ndi mkuwa, faifi tambala, ndi zinthu zina zolimbana ndi dzimbiri. Iwo ali ndi makhalidwe a chitsulo mphamvu, ductility, kupanga, kuwotcherera, kuvala kukana, kutentha, kutopa ndi zina zotero; Kukana kwa nyengo ndi 2 ~ 8 nthawi ya chitsulo cha carbon wamba, ndipo ntchito yophimba ndi 1.5 ~ 10 nthawi ya carbon steel wamba, yomwe ingagwiritsidwe ntchito popaka zopyapyala, zopanda kanthu kapena zophweka. Chitsulocho chimakhala ndi zotsutsana ndi dzimbiri, kukana kwa dzimbiri, moyo wautali, kupatulira ndi kuchepetsa kugwiritsira ntchito, kupulumutsa ntchito ndi kupulumutsa mphamvu, zomwe zimapindulitsa kwa opanga zigawo ndi ogwiritsa ntchito.
Makhalidwe akuluakulu a zinthu za Q450NQR1 amatanthawuza chitsulo chochepa cha alloy structural chitsulo chokhala ndi chitetezo chotsutsana ndi dzimbiri komanso kukana kwa mlengalenga, zomwe zingagwiritsidwe ntchito popanga zitsulo monga magalimoto, milatho, nsanja, ndi zotengera. Poyerekeza ndi carbon steel, weathering chitsulo ali bwino dzimbiri kukana mu mlengalenga. Poyerekeza ndi chitsulo chosapanga dzimbiri, chitsulo chozizira chimakhala ndi zinthu zochepa chabe, monga phosphorous, mkuwa, chromium, faifi tambala, molybdenum, niobium, vanadium, titaniyamu, ndi zina zotero. chitsulo, chomwe chimafika 100%. Khumi peresenti, kotero mtengo ndi wochepa.
