Mukana mukuru wekuumbwa kwemakemikari eQ450NQR1 simbi ndeyekuti inogadzirwa neyakajairwa kabhoni simbi uye ine zvidiki zvemhangura, nickel, uye zvimwe zvinodzivirira corrosion. Iyo ine hunhu hwesimbi simba, ductility, kuumba, welding, kupfeka kuramba, tembiricha yepamusoro, kuneta uye zvichingodaro; Kupokana kwemamiriro ekunze ndeye 2 ~ 8 nguva yeyakajairwa kabhoni simbi, uye kuita kwekupotera kuri 1.5 ~ 10 nguva yeyakajairwa kabhoni simbi, iyo inogona kushandiswa kune yakatetepa, isina kana yakapfava machira. Simbi ine hunhu hwekurwisa ngura, kusimba kwemarara, hupenyu hurefu, kuonda uye kuderedzwa kwekushandisa, kuchengetedza basa uye kuchengetedza simba, izvo zvinobatsira kune vanogadzira zvikamu nevashandisi.
Hunhu hukuru hweQ450NQR1 zvinhu zvinoreva simbi yakaderera-alloy simbi ine inodzivirira anti-ngura layer uye mumhepo inodzivirira kubva kune corrosion, iyo inogona kushandiswa kugadzira zvivakwa zvesimbi senge mota, mabhiriji, shongwe, uye midziyo. Kuenzaniswa nekabhoni simbi, weathering simbi ine nani corrosion resistance mumhepo. Kuenzaniswa nesimbi isina tsvina, weathering simbi ine zvishoma chete alloying zvinhu, akadai phosphorus, mhangura, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. Huwandu huzhinji hwealloying zvinhu zvikamu zvishoma kubva muzana, zvakasiyana zvisina tsvina. simbi, iyo inosvika 100%. Gumi muzana, saka mutengo wakaderera.
