Rail teknik jwe yon wòl enpòtan nan gwo-sistèm teknik ak enstalasyon pò yo, paske materyèl li yo detèmine rezistans nan mete, kapasite chaj, ak lavi sèvis nan tren an. Dapre estanda Chinwa aYB/T 5055-2014 pou ray teknik, materyèl ki pi souvan itilize yo seU71Mn, U75V, ak U78CrV. Sa yo se gwo -aye alyaj ki sibi tretman chalè espesyal pou kenbe tèt ak gwo-frekans ak chaj enpak.
- U71Mn trense klas ki pi lajman itilize, ki gen 0.65-0.76% kabòn ak 0.70-1.40% Manganèz, ak yon fòs rupture ki pi gran pase oswa egal a 880 MPa. Li ofri solidite balanse ak rezistans fatig, sa ki fè li ideyal pou trepye jeneral ak aplikasyon pou chaj mwayen-.
- U75V trengen ladan vanadyòm (0.04-0.12%), ki rafine estrikti grenn lan, ogmante dite ak rezistans enpak ak yon fòs rupture ki pi gran pase oswa egal a 980 MPa. Li souvan itilize pou trepye anlè ak operasyon lou-pò.
- U78CrV trense opsyon ki pi wo -pèfòmans, ki gen chromium (0.30–0.50%) ak vanadyòm (0.04–0.12%) ak yon fòs rupture ki pi gran pase oswa egal a 1080 MPa. Li bay rezistans siperyè mete ak kontwòl deformation, ideyal pou plant metaliji, chantye bato, ak sistèm teknik pò.
