What is Q235B steel?
Q235B steel plate is a remarkable example of low carbon steel, celebrated for its versatile applications. As per the esteemed national standard GB/T 700-2006, 'Carbon Structural Steel,' this material is precisely defined and stands as one of China's most widely used steel products. Its affordability makes Q235B an ideal choice for manufacturing a wide array of products where extremely high performance is not a critical requirement. With its reliable qualities and economical advantage, Q235B steel is the backbone of numerous industrial applications.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies in the subtle variations of carbon content within these carbon steels. Under the national standard GB700-88, this differentiation is pivotal. Specifically, Q235A is characterized by a carbon content ranging from 0.14% to 0.22%, which marks the primary variance between these steel grades. This nuanced difference in composition further enhances the application potentials of each type in diverse scenarios.
Generally, before steel profiles depart from the factory, they are marked with identification plates by steel mills. This practice allows users to discern whether the material is Q235A, Q235B, or other specified types. The design pressure is optimally set at P≤1.6MPa, with the steel effectively performing within a temperature range of 0 to 350ºC. Notably, a steel plate thickness of at least 20mm ensures the material's durability and strength for demanding applications.
The Application of Q235B Steel
Q235B steel grade stands as a stalwart in the realm of civil engineering, playing a pivotal role in constructing a myriad of structures. Renowned for its robustness, Q235B steel is frequently employed in fabricating industrial and residential buildings, integral parts of power transmission towers, critical equipment components, offshore infrastructures, oil and gas platforms, as well as automobile bridges. Its widespread usage underscores its reliability and indispensable nature in modern construction and engineering.
