Q235B be used for welding, bolt connection, riveting structure. as Buildings, Bridges, ships, vehicles structure, manufacturing a variety of tools and cutters, mould and measuring tool, etc.Q235B mild steel round bar and flat sections can be cut to your required sizes.
Relatively speaking, the mechanical properties of Q235B steel plate are far superior to those of Q235A steel plate. In the national standard GB700-88, the materials of Q235A steel plate and Q235B steel plate are mainly divided into the carbon content of steel. Q235A steel plate material has not been tested by impact. Q235B steel plate material is normal temperature impact test, V-shaped notch.
