What is Q235B steel?
Q235B steel plate is a highly versatile and widely used form of low carbon steel. As defined by the prestigious national standard GB/T 700-2006 "Carbon Structural Steel," Q235B has earned its place as one of the most prevalent steel products in China. Its affordability and adaptability make it ideal for a multitude of applications where high performance is not a strict requirement.
The difference between Q235A and Q235B.
Exploring the difference between Q235A and Q235B reveals that both are esteemed carbon steels. According to the national standard GB700-88, the distinguishing factor primarily lies in their carbon content. Specifically, Q235A exhibits a carbon content range of 0.14-0.22%, setting it apart in composition.
In standard practice, steel mills meticulously mark the finished profiles with identification plates before shipment. This allows the user to ascertain whether the material in question is Q235A, Q235B, or another type. The design parameters include a pressure limitation of P≤1.6MPa, a usage temperature ranging from 0 to 350ºC, and a steel plate thickness of at least 20mm.
The Application of Q235B Steel
Steel grade Q235B is indispensable in the realm of civil engineering, fulfilling a critical role in the construction of both industrial and residential infrastructure. From erecting steel structures and fabricating parts for power transmission towers to building elements of equipment and offshore structures, Q235B is at the core. It also contributes to the creation of oil and gas platforms, automobile bridges, and a wide array of other structural marvels.
