What is Q235B steel?
Q235B steel plate is a renowned low carbon steel, defined by the prestigious national standard GB/T 700-2006 'Carbon Structural Steel.' Celebrated as one of China's most common steel products, Q235B is prized for its affordability and versatility. Ideal for products that do not demand high performance, it offers a practical solution for diverse applications.
The difference between Q235A and Q235B.
The intricate distinction between Q235A and Q235B carbon steels lies in their carbon content as per the esteemed national standard GB700-88. Q235A material boasts a carbon content ranging from 0.14% to 0.22%, defining its unique properties.
Typically, steel mills meticulously mark the finished profiles on identification plates before departure from the factory. Users can conveniently assess whether the material is Q235A, Q235B, or other, using the identification plate. Designed for a maximum pressure of P≤1.6MPa, with a temperature range of 0~350ºC and a steel plate thickness of 20mm or more.
The Application of Q235B Steel
The robust Q235B steel grade is extensively utilized to bring to life innovative civil engineering solutions. Its versatility shines in the construction of industrial and residential structures, power transmission towers, and critical elements of machinery. Additionally, it is foundational in offshore structures, oil and gas platforms, automobile bridges, and an array of other pivotal structures.
