What is Q235B steel?
Q235B steel plate is a highly versatile type of low carbon steel. Defined clearly under the national standard GB/T 700-2006 'Carbon Structural Steel', Q235B sits among the most prevalent steel products in China. This economic option is favored for applications that do not demand high performance, making it both cost-effective and widely usable.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies primarily in their carbon content, both classified as carbon steels under the GB700-88 standard. Specifically, Q235A features a carbon range of 0.14-0.22%, which defines its material properties in comparison to Q235B.
Typically, steel mills imprint the identification plates of finished profiles with relevant details before they dispatch them from the factory. Users can verify whether the material is Q235A, Q235B, or another type on these plates. It supports design pressures of P≤1.6MPa and a usage temperature from 0~350ºC, with a steel plate thickness of at least 20mm.
The Application of Q235B Steel
Widely embraced for its versatility, steel grade Q235B is instrumental in civil engineering projects. It is the backbone of steel structures used in the construction of both industrial and residential buildings, power transmission towers, and various equipment components. Its applications extend to offshore structures, oil and gas platforms, automobile bridges, and beyond.
