GB / T1591 Q390E Tsawg Alloy Hlau Phajmuaj lub zog tsawg tensile lub zog ntawm 490 mpa kom muaj lub zog ntawm kev rho tawm lub zog ntawm cov kua txiv.
Khoom nta
I. Muaj kev ruaj khov ntawm cov khoom siv me txhua yam
Sib npaug ntawm lub zog thiab tawv
Q390E muaj ib qho txiaj ntsig lub zog ntawm ntau dua lossis sib npaug nrog 390MPA thiab lub tensile lub zog xws li ntawm 520-680MPA. Los ntawm kev ntxiv cov qauv microalloy xws li NB, V, thiab TI mus rau 0.20%), nws ua tiav qhov sib npaug ntawm lub zog siab thiab lub zog zoo. Hauv kev kawm tshwj xeeb, "E" E "kev cuam tshuam loj dua lossis muaj kev sib luag ntawm cov qib qis dua lossis muaj kev pheej hmoo ntawm brittle begiture ntawm cov mob txias.
Tsawg Tshaj Tawm Kev Ua Tau Zoo Li Cas
Dhau ntawm cov txheej txheem dov nruj (piv txwv li, tswj kev dov thiab cua txias) thiab lub zog} {{2} {{2}
