What is Q235B steel?
Q235B steel plate is a versatile, low carbon steel widely recognized in China for its superior cost-effectiveness. According to the national standard GB/T 700-2006 'Carbon Structural Steel', Q235B stands out as a prominent steel product with remarkable affordability. It is extensively employed in applications where high-end performance is not a primary requirement.
The difference between Q235A and Q235B.
Q235A and Q235B are categorized under carbon steels as per the national standard GB700-88. The principal difference lies in the carbon content between these materials. Specifically, Q235A is characterized by a carbon content range of 0.14-0.22%, distinguishing it from its counterpart, Q235B.
Typically, steel mills inscribe the identification details of finished steel profiles on plates prior to dispatch. These identification plates enable users to discern whether the material is Q235A, Q235B, or another classification. Design pressure is specified at P≤1.6MPa, with a usable temperature range from 0 to 350ºC, and a minimum steel plate thickness of 20mm.
The Application of Q235B Steel
Q235B steel grade is an integral component in the realm of civil engineering, facilitating the construction of both industrial and residential infrastructures. This steel grade is essential in forming robust steel structures, pivotal for building power transmission towers, various equipment components, offshore structures, oil and gas platforms, vehicle bridges, and a myriad of other key constructions.
