Unveiling the Essentials: What is Q235B Steel?
Q235B steel plate represents a versatile and economical choice in the realm of low carbon steels. As clearly defined by the national standard GB/T 700-2006, 'Carbon Structural Steel', Q235B stands as a cornerstone in the Chinese steel market. It offers exceptional cost-effectiveness, making it ideal for applications where superior performance is not a critical requirement.
Delving Into Differences: Q235A vs. Q235B
The distinction between Q235A and Q235B carbon steels is fundamental yet significant. According to the national standard GB700-88, these differences primarily hinge on the carbon content. Specifically, Q235A encompasses a carbon content range of 0.14-0.22%, setting it apart in material characteristics.
Typically, before leaving the factory, steel mills affix identification plates to finished profiles, allowing users to determine whether the material is Q235A, Q235B, or another variant. These identifications ensure the specifications: Design pressure P≤1.6MPa; operational temperature range 0~350ºC; and steel plate thickness of at least 20mm.
Exploring the Applications of Q235B Steel
Q235B steel grade plays a pivotal role in civil engineering, forming the backbone of many structural solutions. Its robust properties are harnessed in the construction of both industrial and residential buildings. Additionally, it is instrumental in fabricating components for power transmission towers, various equipment, offshore structures, oil and gas platforms, automotive bridges, and more.
