Steel Rolling 27 (2010) 18-19.  C. Oberbillig, M. Huang, O. Bouaziz, K. Zhu, An approach to define the effective lath size controlling yield strength of bainite, J. Materials Science & Engineering, A. Structural Experimental cyclic behavior and constitutive modeling of Nov 20, 2018 · High strength structural steels exhibit appreciable strength but insufficient deformability. The yield-to-tensile ratios for Q550D, Q690D and Q890D are more than 0.90, while the elongations range from 12% to 20%, indicating that these three structural steels are prohibited according to current Chinese seismic code.
When the Q550D steel sheet is required to have a thickness direction property, a symbol representing the thickness direction (Z direction) performance level is added to the predetermined grade, for example, Q550D-Z15. Q550D steel is mainly used in important (low temperature) high-strength structural parts, engineering machinery, mining and other steel structures.
