What is Q235B steel?
Q235B steel plate, an exceptional low carbon steel, stands out as a vital component under the national standard GB/T 700-2006 'Carbon Structural Steel.' As one of the most prevalent steel products in China, Q235B offers an economical solution for a multitude of applications that do not demand high-performance specifications.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies primarily in their carbon content, as categorized under the national standard GB700-88. Both being carbon steels, Q235A features a carbon content ranging from 0.14% to 0.22%, offering varying degrees of strength and flexibility to cater to diverse application needs.
In standard practice, steel mills affix identification plates to finished profiles prior to factory release. These plates enable users to identify whether the material is Q235A, Q235B, or an alternative grade. Notably, the design parameters include a pressure tolerance of P≤1.6MPa, operational temperatures between 0~350ºC, and a minimum steel plate thickness of 20mm.
The Application of Q235B Steel
Q235B steel is integral in realizing civil engineering projects. This steel grade is instrumental in constructing industrial and residential infrastructures, components of power transmission towers, essential parts of equipment, offshore platforms, oil and gas facilities, as well as automobile and pedestrian bridges, showcasing its versatile application in various structural scenarios.
