What is Q235B Steel?
Q235B steel plate is a versatile low carbon steel that is clearly defined under the national standard GB/T 700-2006 'Carbon Structural Steel'. Renowned as one of China's most prevalent steel products, Q235B stands out for its affordability and adaptability. Its cost-effectiveness makes it ideal for applications where high performance is not a primary requirement, offering a reliable and efficient solution for various industries.
The Difference Between Q235A and Q235B.
The difference between Q235A and Q235B is primarily based on their carbon content, as classified under the national standard GB700-88. Q235A features a carbon content ranging from 0.14-0.22%, distinguishing it from Q235B within the carbon steel category.
Typically, steel mills label finished profiles with identification plates before they leave the factory. Users can determine if the material is Q235A, Q235B, or other types of steel by examining these plates. Designed for pressures up to 1.6MPa, and usable in temperatures from 0 to 350ºC, the steel plate maintains a thickness of at least 20mm to ensure durability and performance.
The Application of Q235B Steel
The steel grade Q235B is extensively employed in civil engineering projects. Its application spans the construction of industrial and residential facilities, components for power transmission towers, equipment elements, offshore structures, oil and gas platforms, automobile bridges, and numerous other structural uses, making it a cornerstone in modern infrastructure development.
