What is Q235B steel?
Q235B steel plate is a type of low carbon steel renowned for its versatility and affordability. Defined by the national standard GB/T 700-2006 'Carbon Structural Steel', Q235B stands as one of China's most ubiquitous steel products. Its cost-effectiveness makes it ideal for a wide range of applications where the demand for high performance is not critical.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies in their carbon content, although both are carbon steels. According to the national standard GB700-88, Q235A features a carbon content of 0.14-0.22%, which differentiates it from Q235B. This variance in carbon content affects the material properties and suitability for specific applications.
Typically, steel mills label the finished profiles on identification plates before dispatch. Users can determine whether the material is Q235A, Q235B, or other types from these plates. It is essential for applications where design pressure is P≤1.6MPa, operational temperatures range from 0~350ºC, and where steel plate thickness must be at least 20mm.
The Application of Q235B Steel
Q235B steel grade is extensively utilized in civil engineering projects. Due to its robust and flexible nature, it's the go-to choice for constructing industrial and residential buildings, components of power transmission towers, equipment parts, offshore structures, oil and gas platforms, automobile bridges, and various other structural applications.
