What is Q235B steel?
Q235B steel plate is a type of low carbon steel that is defined by the national standard GB/T 700-2006 "Carbon Structural Steel." Widely recognized as one of the most prevalent steel products in China, Q235B is valued for its cost-effectiveness and versatility. This steel is ideal for manufacturing a wide range of products that do not necessitate high-performance attributes, making it a staple in numerous industries.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B steels lies in their carbon content, as outlined in the national standard GB700-88, which categorizes both as carbon steels. Specifically, Q235A steel features a carbon content ranging from 0.14-0.22%. This difference in composition plays a crucial role in the selection process based on mechanical requirements and application suitability.
Under typical conditions, steel mills label finished profiles on their identification plates prior to factory departure. Users can determine whether the material is Q235A, Q235B, or another type by examining the identification plate. The design specifications indicate pressure P≤1.6MPa, operating temperatures from 0 to 350ºC, and steel plate thickness of at least 20mm.
The Application of Q235B Steel
Q235B steel grade is highly sought after for its robust application in civil engineering projects. Esteemed for its structural integrity, Q235B is instrumental in fabricating steel structures for both industrial and residential buildings, components of power transmission towers, and elements of complex equipment. It is also a preferred choice for offshore constructions, oil and gas platforms, automotive bridges, and various other structural frameworks.
