What is Q235B steel?
Q235B steel plate is a type of low carbon steel that is well-defined under the national standard GB/T 700-2006 "Carbon Structural Steel." As one of the most prevalent steel products in China, Q235B is prized for its cost-effectiveness, making it an optimal choice for numerous applications where high performance is not a critical requirement. Its versatility and affordability make it a staple in the industry.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B carbon steels is primarily based on their carbon content as outlined in the national standard GB700-88. Q235A steel features a carbon content ranging from 0.14% to 0.22%, setting it apart from its Q235B counterpart.
Typically, before dispatch from the factory, steel mills affix identification plates to the finished profiles. These plates enable users to determine whether the material is Q235A, Q235B, or another variant. The design parameters include a maximum pressure of P≤1.6MPa and a usage temperature ranging from 0~350ºC, with a steel plate thickness of at least 20mm.
The Application of Q235B Steel
Q235B steel is highly valued in civil engineering for its adaptability. It is the material of choice for constructing robust steel structures in both industrial and residential projects. Its applications extend to power transmission towers, equipment components, offshore platforms, oil and gas platforms, and automobile bridges, underlining its importance in infrastructure development.
