What is Q235B steel?
Q235B steel plate is a renowned type of low carbon steel, explicitly defined by the national standard GB/T 700-2006 'Carbon Structural Steel'. Q235B stands as one of China's most prevalent steel products, celebrated for its affordability and versatility, making it suitable for a wide range of applications where high performance is not a critical requirement.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B involves their classification as carbon steels. According to the national standard GB700-88, the distinction lies primarily in their carbon content. Q235A consists of carbon within the range of 0.14-0.22%;
Typically, steel mills label finished profiles on identification plates before dispatch. These plates enable users to discern whether the material is Q235A, Q235B, or another variant. The design pressure is P≤1.6MPa, suitable for temperatures ranging from 0~350ºC, with a steel plate thickness of no less than 20mm.
The Application of Q235B Steel
Q235B steel is extensively utilized in civil engineering solutions. It serves as a primary material for constructing industrial and residential facilities, power transmission tower components, equipment elements, offshore structures, oil and gas platforms, automobile bridges, and various other robust structures.
