Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between SA572 Grade 42 structural steel strip, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.
