What is Q235B steel?
Q235B steel plate epitomizes a versatile and budget-friendly low carbon steel. Defined precisely by the national standard GB/T 700-2006 'Carbon Structural Steel', Q235B stands as one of the most ubiquitous steel products within China's vast market. Its affordability makes it an ideal choice for a wide range of products that do not demand high-performance attributes, thus serving myriad needs with economic efficiency.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies in their classification as carbon steels per the national standard GB700-88. The primary difference is found in the carbon content: Q235A boasts a carbon content ranging from 0.14% to 0.22%.
In standard practice, steel mills inscribe the identification plates of finished profiles before dispatch. These plates allow users to discern whether the material is Q235A, Q235B, or another variant. Design pressure is maintained at P≤1.6MPa; operational temperatures span from 0 to 350ºC, and the steel plate thickness is no less than 20mm.
The Application of Q235B Steel
Steel grade Q235B is extensively employed in civil engineering projects. Its utility in crafting robust steel structures makes it indispensable for constructing industrial and residential complexes, power transmission towers, equipment components, offshore installations, oil and gas platforms, and even automobile bridges, showcasing its adaptability and strength across various structural applications.
