O le aoga autu o le vailaʻau vailaʻau o Q450NQR1 uamea o loʻo faia i le carbon steel masani ma o loʻo i ai ni vaega laiti o kopa, nickel, ma isi elemene faʻafefe. O loʻo i ai uiga o le malosi uʻamea, ductility, faia, faʻapipiʻi, ofuina teteʻe, vevela maualuga, vaivai ma isi; O le tetee o le tau e 2 ~ 8 taimi o le uamea masani masani, ma o le faʻaogaina o le faʻapipiʻiina o le 1.5 ~ 10 taimi o le uamea masani masani, lea e mafai ona faʻaaogaina mo faʻamaʻi manifinifi, paʻu pe faʻafaigofie. O le uʻamea o loʻo i ai uiga o le anti-rust, corrosion resistance, umi le ola, thinning ma le faʻaitiitia o le faʻaaogaina, faʻasaoina o galuega ma le faʻaolaina o le malosi, lea e aoga i tagata gaosi oloa ma tagata faʻaoga.
O uiga autu o Q450NQR1 meafaitino e faasino i le uʻamea faʻapipiʻi maualalo faʻatasi ma le puipuiga o le anti-rust layer ma le atmospheric corrosion resistance, lea e mafai ona faʻaaogaina e gaosia ai fausaga uʻamea e pei o taavale, alalaupapa, olo, ma pusa. Pe a faatusatusa i le carbon steel, weathering steel e sili atu le tetee i le corrosion i le siosiomaga. Pe a faatusatusa i uʻamea uʻamea, weathering uʻamea e na o se vaega itiiti o alloying elemene, e pei o phosphorus, kopa, chromium, nickel, molybdenum, niobium, vanadium, titanium, ma isi. sila, lea e oʻo atu i le 100%. Sefulu pasene, o lona uiga e maualalo le tau.
