What is Q235B steel?
Q235B steel plate is an economical, low carbon steel that is prominently defined in the national standard GB/T 700-2006 'Carbon Structural Steel.' As one of China's most ubiquitous steel types, Q235B is celebrated for its affordability and versatility. It effortlessly accommodates a wide array of applications where high performance is not imperative.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies within their classification as carbon steels. According to the national standard GB700-88, the primary difference is their varying carbon content. Q235A features a carbon content range of 0.14-0.22%. Such variations contribute to different mechanical properties and usability.
In typical scenarios, steel mills meticulously label finished profiles on identification plates before dispatch. These plates enable users to discern the material type, be it Q235A, Q235B, or others. With design pressures capped at P≤1.6MPa and operational temperatures ranging from 0 to 350ºC, the steel's thickness starts at 20mm, ensuring robust and reliable performance.
The Application of Q235B Steel
Steel grade Q235B is extensively employed in civil engineering projects due to its robust properties. From industrial complexes and residential facilities to power transmission towers and offshore platforms, Q235B is pivotal in the construction of oil and gas infrastructures, automobile bridges, and myriad other structures, offering unmatched reliability and strength.
