What is the difference between Q235A steel and Q235B steel? First, The carbon content of Q235A steel is 0.22%, higher than that of Q235B steel, which is 0.20%. The sulfur content of Q235A steel is 0.050%, higher than that of Q235B steel, which is 0.045%. Second, S890QL equivalent steel, Q235 material belongs to carbon structural steel. The English letters A and B at the back have different meanings. They are impact temperature requirements. Q235A steel is not subject to impact, while Q235B steel is subject to 20 ℃ room temperature impact.
