What is Q235B steel?
Q235B steel plate represents a versatile and economical choice in the realm of low carbon steels. Defined clearly by the national standard GB/T 700-2006 'Carbon Structural Steel', Q235B stands out as a widely utilized steel product in China. Due to its affordability, it is ideal for a broad spectrum of products that do not demand exceptionally high performance.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B: Both are types of carbon steels. According to the national standard GB700-88, Q235A and Q235B are primarily distinguished by their carbon content. The carbon content for Q235A ranges between 0.14% and 0.22%, offering unique material properties.
Ordinarily, steel mills ensure that the finished profiles are marked on identification plates before dispatch. Users can ascertain if the material is Q235A, Q235B, or another type from the identification plate. These materials are suitable for applications with design pressure P≤1.6MPa and operational temperatures from 0 to 350ºC, with steel plate thickness starting from 20mm.
The Application of Q235B Steel
Steel grade Q235B is extensively employed for various civil engineering and construction solutions. It is the material of choice for creating robust steel structures in both industrial and residential settings. Additionally, it finds application in power transmission towers, equipment components, offshore structures, oil and gas platforms, as well as automobile bridges, among other constructions.
