Q550E Cov Qauv Hlau
Q550qE yog qib siab choj phaj uas ua raws li GB/T16270-2009 tus qauv. Q stands rau yield zog. Tus nqi zog tawm los ntawm 500 yog: 550MPa. q stands rau choj steel phaj thiab E stands rau qib zoo. Nws kuj sawv cev rau qhov sib txawv ntawm qhov kub thiab txias, E sawv cev rau -40 degree cuam tshuam. Muaj peb theem zoo: Q550qC, Q550qD, thiab Q550qE.
