What is Q235B steel?
Q235B steel plate is a versatile and economical low carbon steel, renowned for its prominent role in the national standard GB/T 700-2006 'Carbon Structural Steel.' As one of the most prevalent steel products in China, its affordability and reliability make it ideal for a myriad of applications, especially those that do not necessitate high-performance attributes.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B: Both are quintessential carbon steels. According to the national standard GB700-88, the primary distinction lies in their carbon content. Q235A features a carbon range of 0.14-0.22%;
Typically, steel mills ensure precision by marking the completed profiles on identification plates before dispatch. Users can ascertain whether the material is Q235A, Q235B, or another by simply checking the identification plate. Ideal for design pressure P≤1.6MPa, operational temperature span 0~350ºC, and steel plate thickness of no less than 20mm.
The Application of Q235B Steel
Steel grade Q235B is critically important for various civil engineering endeavors. It serves as the backbone for constructing industrial and residential infrastructures, components of power transmission towers, and elements of sophisticated equipment. Q235B steel also supports the framework of offshore structures, oil and gas platforms, and automobile bridges, among other architectural and industrial structures.
