What is Q235B steel?
Q235B steel plate is a remarkable type of low carbon steel, prominently defined in the national standard GB/T 700-2006, known as 'Carbon Structural Steel.' Widely recognized as one of China's most prevalent steel products, Q235B is highly economical and suitable for a vast range of applications that do not demand superior performance levels.
The difference between Q235A and Q235B.
Delving into the distinction between Q235A and Q235B: both are carbon steels as specified in the national standard GB700-88. The key differentiator lies in carbon content; Q235A features a carbon content ranging from 0.14% to 0.22%, offering unique material characteristics.
In typical scenarios, steel mills imprint the finished profiles with identification marks before dispatching them from the factory. These identification plates enable users to ascertain whether the material is Q235A, Q235B, or any other type. With design pressure conditions of P≤1.6MPa, operational temperature ranges of 0~350ºC, and a steel plate thickness of >=20mm, these specifications ensure optimal usage.
The Application of Q235B Steel
Renowned for its versatility, steel grade Q235B is extensively employed in civil engineering as a vital component for steel structures. From constructing industrial and residential facilities to forming parts of power transmission towers, this grade is instrumental in building offshore structures, oil and gas platforms, automobile bridges, and other significant infrastructure projects.
