What is Q235B steel?
Q235B steel plate is a low carbon steel variety defined by the national standard GB/T 700-2006 "Carbon Structural Steel." Revered for its affordability, Q235B stands as one of the most prevalent steel products across China. Its economical nature makes it an ideal choice for applications where high performance is not a critical requirement.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B: Both belong to the carbon steel family. According to the national standard GB700-88, the primary distinction lies in their carbon content. Q235A's carbon content ranges between 0.14-0.22%.
Typically, steel mills label finished profiles on identification plates before dispatch. These plates help users ascertain whether the material is Q235A, Q235B, or another variant. For Q235B, the design pressure is P≤1.6MPa; it is suitable for use at temperatures ranging from 0 to 350ºC, with a steel plate thickness of >=20mm.
The Application of Q235B Steel
The Q235B steel grade plays a pivotal role in a variety of civil engineering applications. It is instrumental in fabricating steel structures for industrial and residential buildings, power transmission tower components, equipment parts, offshore structures, oil and gas platforms, automobile bridges, and numerous other structural applications.
