What is Q235B steel?
Q235B steel plate is a remarkably versatile type of low carbon steel, renowned for its inclusion in the national standard GB/T 700-2006, "Carbon Structural Steel," where it's defined with precision and clarity. Widely recognized as one of China's quintessential steel products, Q235B stands out for its economical viability. It is predominantly utilized for a myriad of applications not demanding extraordinary performance, making it a staple in the steel industry.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies in their classification as carbon steels. According to the national standard GB700-88, the primary variance is attributed to the carbon content in the steel. Q235A encompasses a carbon content range of 0.14-0.22%, whereas Q235B is subjected to different specifications and applications, offering varied properties tailored to specific needs.
Typically, before leaving the factory, steel mills ensure that finished profiles are prominently marked on identification plates. These markings allow users to discern whether the material is Q235A, Q235B, or other variations. The design parameters include a pressure P≤1.6MPa, an operational temperature between 0~350ºC, and a steel plate thickness of at least 20mm, providing users with guidance on appropriate applications.
The Application of Q235B Steel
Q235B steel grade is integral in delivering solutions for civil engineering projects. Renowned for its robustness, Q235B is employed in crafting steel structures for various applications, including the construction of both industrial and residential buildings, components of power transmission towers, and essential parts of equipment. It is also instrumental in offshore platforms, oil and gas platforms, automobile bridges, and a broad spectrum of other structural entities, underscoring its versatility and widespread use.
