Inzuzo ephambili yokubunjwa kweekhemikhali ze-Q450NQR1 yentsimbi kukuba yenziwe ngentsimbi yekhabhoni eqhelekileyo kwaye iqulethe ixabiso elincinci lobhedu, i-nickel, kunye nezinye izinto ezichasene ne-corrosion. Ineempawu zamandla ensimbi, i-ductility, ukubunjwa, i-welding, ukumelana nokugqoka, ukushisa okuphezulu, ukukhathala njalo njalo; Ukuxhatshazwa kwemozulu ngama-2 ~ 8 amaxesha e-carbon steel eqhelekileyo, kunye nokusebenza kokugqoka ku-1.5 ~ 10 amaxesha e-carbon steel eqhelekileyo, enokuthi isetyenziswe kwiingubo ezincinci, ezingenanto okanye ezilula. Intsimbi ineempawu zokuchasana ne-rust, ukumelana nokugqwala, ubomi obude, ukunciphisa kunye nokunciphisa ukusetyenziswa, ukugcinwa kwabasebenzi kunye nokugcinwa kwamandla, okunenzuzo kubakhiqizi becandelo kunye nabasebenzisi.
Iimpawu eziphambili zezinto ze-Q450NQR1 zibhekiselele kwintsimbi ephantsi ye-alloy yesakhiwo kunye ne-anti-rust layer ekhuselayo kunye nokumelana ne-atmospheric corrosion, engasetyenziselwa ukuvelisa izakhiwo zentsimbi ezifana neenqwelo, iibhulorho, iinqaba kunye nezikhongozeli. Xa kuthelekiswa nentsimbi ye-carbon, i-weathering steel inokumelana nokugqwala okungcono kwi-atmosfera. Xa kuthelekiswa nensimbi engenasici, i-weathering steel inomlinganiselo omncinci wezinto ezixutywayo, ezifana ne-phosphorus, ubhedu, i-chromium, i-nickel, i-molybdenum, i-niobium, i-vanadium, i-titanium, njl njl. intsimbi, efikelela kwi-100%. Ipesenti ezilishumi, ngoko ixabiso liphantsi.
