Understanding Q235B Steel
Q235B steel plate: A quintessential example of low carbon steel, distinctly defined by the national standard GB/T 700-2006, 'Carbon Structural Steel.' As one of China's most prevalent steel products, it offers a cost-effective solution for a wide range of basic applications, where high performance isn't a necessity.
Distinguishing Between Q235A and Q235B
Exploring the Differences between Q235A and Q235B: These carbon steels, as classified in the national standard GB700-88, differ primarily in carbon content. Q235A boasts a carbon content range of 0.14-0.22%, defining its unique characteristics.
Typically, prior to dispatch from the factory, steel mills inscribe identification plates on finished profiles, allowing users to determine whether the steel is Q235A, Q235B, or another type. These materials are crafted to withstand design pressures of P≤1.6MPa and function at temperatures between 0 to 350ºC, with a minimum steel plate thickness of 20mm.
Versatile Applications of Q235B Steel
The Q235B steel grade is a cornerstone for civil engineering feats. Ideal for constructing industrial and residential frameworks, Q235B is utilized in crafting robust steel structures for power transmission towers, industrial apparatus, offshore platforms, oil and gas infrastructure, automobile bridges, and much more, illustrating its diverse utility.
