What is Q235B steel?
Q235B steel plate is a distinguished type of low carbon steel, proudly defined by the national standard GB/T 700-2006 'Carbon Structural Steel'. Renowned across China, Q235B is not only economical but also versatile, making it ideal for a multitude of applications that do not demand superior performance.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies chiefly in their carbon content, as specified in the national standard GB700-88. Q235A comes with a carbon content range of 0.14-0.22%, marking a key difference from Q235B.
Typically, steel mills affix identification plates on finished profiles prior to dispatch, enabling users to discern whether the material is Q235A, Q235B, or another grade. These plates also provide insights on the design pressure, up to ≤1.6MPa, operational temperature range of 0~350ºC, and a minimum steel plate thickness of 20mm.
The Application of Q235B Steel
Q235B steel is foundational in civil engineering projects. It is the material of choice for constructing both industrial and residential infrastructures, forming integral parts of power transmission towers, equipment components, offshore structures, oil and gas platforms, automotive bridges, and various other structural applications.
