What Exactly is Q235B Steel?
Q235B steel plate is a quintessential example of low carbon steel with a well-defined specification under the national standard GB/T 700-2006, known as "Carbon Structural Steel." Renowned across China as one of the most prevalent steel products, Q235B offers affordability and versatility. It is particularly suitable for applications that don't demand high performance, making it a practical choice for a vast array of projects.
Exploring the Distinctions between Q235A and Q235B
Unveiling the differences between Q235A and Q235B: Both are carbon steels delineated by the national standard GB700-88, with their primary distinction lying in their carbon content. Specifically, Q235A features a carbon content range of 0.14-0.22%. This subtle variance in composition can influence material choice depending on specific project requirements.
Typically, steel mills ensure that the finished profiles are marked on identification plates before their departure from the factory. These plates serve as a reliable method for users to discern the material type—be it Q235A, Q235B, or others. With a design pressure capability of P≤1.6MPa, operational temperature ranging from 0 to 350ºC, and a requisite steel plate thickness of at least 20mm, Q235B steel is engineered for robust performance.
Versatile Applications of Q235B Steel
The Q235B steel grade is celebrated for its extensive application in civil engineering endeavors. It is integral in crafting steel structures for both industrial and residential construction projects. This steel is essential for components of power transmission towers, various equipment elements, offshore structures, oil and gas platforms, automobile bridges, and a multitude of other architectural and infrastructural ventures.
