What is Q235B steel?
Q235B steel plate is a type of low carbon steel that is defined by the national standard GB/T 700-2006 "Carbon Structural Steel." Renowned for its cost-effectiveness, Q235B is one of the most widely used steel products in China, perfectly suitable for a range of applications that do not demand high performance.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B steels lies predominantly in their carbon content, as specified in the national standard GB700-88. Q235A steel contains 0.14-0.22% carbon, offering unique characteristics compared to its counterpart.
Typically, steel mills label the finished profiles on identification plates before dispatch. Users can determine whether the material is Q235A, Q235B, or another type based on this identification. Suitable for design pressures up to 1.6MPa, operational temperatures from 0 to 350ºC, and steel plate thicknesses of at least 20mm.
The Application of Q235B Steel
Q235B steel grade is extensively employed in civil engineering projects. It is the material of choice for crafting steel structures used in the construction of both industrial and residential buildings, components of power transmission towers, and various elements of equipment. Additionally, Q235B is integral to offshore structures, oil and gas platforms, automobile bridges, and more.
