What is Q235B Steel?
Q235B steel plate is a versatile low carbon steel, renowned for its affordability and ubiquity in China. As defined by the national standard GB/T 700-2006 'Carbon Structural Steel', Q235B is a staple product without the demands for high performance, making it ideal for a myriad of applications.
The Difference Between Q235A and Q235B
The distinction between Q235A and Q235B lies primarily in their carbon content. According to the national standard GB700-88, both are carbon steels, yet Q235A contains a carbon content range of 0.14-0.22%, a key differentiator that influences their specific applications and performance levels.
Typically, finished steel profiles are marked on identification plates before leaving the factory, allowing users to determine if the material is Q235A, Q235B, or another type. These plates indicate important specifications: Design pressure up to 1.6MPa, operational temperatures ranging from 0 to 350ºC, and a steel plate thickness of at least 20mm.
The Application of Q235B Steel
Q235B steel is a pivotal component in civil engineering projects due to its adaptability and strength. It's extensively used in the creation of steel structures for industrial and residential buildings, components for power transmission towers, and vital elements in equipment construction. It also plays a crucial role in offshore structures, oil and gas platforms, automobile bridges, and a multitude of other structural applications.
