What is Q235B steel?
Q235B steel plate is a type of low carbon steel, which is meticulously defined under the national standard GB/T 700-2006 for 'Carbon Structural Steel.' This steel variant stands as one of China's most prevalent steel products, offering exceptional affordability. Its cost-effectiveness makes it an ideal choice for a wide array of applications that do not demand top-tier performance attributes.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B: Both are categorized under carbon steels according to the national standard GB700-88. The primary distinction lies in their carbon content. Q235A possesses a carbon content ranging from 0.14-0.22%, setting it apart from Q235B in terms of mechanical properties and applications.
In typical scenarios, manufacturers identify completed profiles with detailed markings on identification plates prior to factory dispatch. This enables users to discern whether the material is Q235A, Q235B, or another variant. Design parameters include pressure P≤1.6MPa, operational temperature between 0~350ºC, and a steel plate thickness of no less than 20mm.
The Application of Q235B Steel
The versatile Q235B steel grade finds extensive application in civil engineering solutions. It forms the backbone of steel structures in both industrial and residential constructions, facilitates components of power transmission towers, and is integral to equipment elements, offshore infrastructures, oil and gas platforms, automotive bridges, among various other structural implementations.
