Qalabka Q450NQR1 waa birta dibadda iyo birta cimilada loo isticmaalo weelasha, shoolada warshadda korontada iyo mashaariicda tareenada, sida birta loogu talagalay sawirada bannaanka ee waaweyn. Birta cimiladu (yacni, birta hawada u adkaysanaysa daxalka) waa taxane bir alwaax ah oo hooseeya oo u dhexeeya birta caadiga ah iyo birta aan la taaban karin, kuwaas oo aan qaali ahayn tayadooduna wanaagsan tahay. Ka dib marka la isku daro habka cusub, tignoolajiyada cusub iyo habka cusub ee birta casriga ah, horumar waara iyo hal-abuurnimo ayaa la gaari karaa oo iska leh adduunka.

Faa'iidada ugu weyn ee ka kooban kiimikada birta Q450NQR1 waa in ay ka samaysan tahay birta kaarboonka ee caadiga ah oo ay ku jirto xaddi yar oo naxaas ah, nikkel, iyo walxo kale oo u adkaysta daxalka. Waxay leedahay sifooyinka xoogga birta, ductility, samaynta, alxanka, xirashada caabbinta, heerkulka sare, daalka iyo wixii la mid ah; Iska caabbinta cimiladu waa 2 ~ 8 jeer ka badan birta kaarboonka ee caadiga ah, waxqabadka daahankuna waa 1.5 ~ 10 jeer ka mid ah birta kaarboonka caadiga ah, kaas oo loo isticmaali karo dahaar khafiif ah, qaawan ama la fududeeyay. Birtu waxay leedahay sifooyin liddi ku ah miridhku, iska caabinta daxalka, nolosha dheer, khafiifinta iyo dhimista isticmaalka, badbaadinta shaqada iyo badbaadinta tamarta, taas oo faa'iido u leh soosaarayaasha qaybaha iyo isticmaaleyaasha.

Astaamaha ugu muhiimsan ee walxaha Q450NQR1 waxay tixraacaan birta qaab dhismeedka hoose ee alloy leh lakabka ka hortagga miridhku ka hortagga iyo iska caabinta daxalka atmospheric, kaas oo loo isticmaali karo in lagu soo saaro qaab dhismeedka birta sida baabuurta, buundooyinka, munaaradaha, iyo weelasha. Marka la barbardhigo birta kaarboonka, birta cimiladu waxay leedahay iska caabbinta daxalka ee jawiga. Marka la barbardhigo birta aan fiicnayn, birta cimiladu waxay leedahay oo kaliya qadar yar oo ah walxo alloying, sida fosfooraska, copper, chromium, nikkel, molybdenum, niobium, vanadium, titanium, iwm. birta, taas oo gaadhaysa 100%. Boqolkiiba toban, markaa qiimuhu waa yar yahay.
