What is Q235B steel?
Q235B steel plate is a widely recognized low carbon steel, defined comprehensively by the national standard GB/T 700-2006 'Carbon Structural Steel.' Renowned for its affordability, Q235B stands as one of the most prevalent steel products in China. Its versatility makes it suitable for a myriad of applications that do not demand high-performance specifications.
The difference between Q235A and Q235B.
Exploring the distinctions between Q235A and Q235B: Both are categorized under carbon steels, as outlined in the national standard GB700-88. The primary differentiation lies in the carbon content. Q235A features a carbon composition ranging from 0.14-0.22%, providing a subtle yet significant variance compared to Q235B.
Typically, steel mills imprint identification plates with key details before the products leave the factory. Users can determine whether the material is Q235A, Q235B, or another specification by referring to these plates. Design pressure is P≤1.6MPa; usage temperature varies from 0~350ºC; and steel plate thickness is maintained at >=20mm.
The Application of Q235B Steel
Q235B steel grade is integral to a wide array of civil engineering projects. It is frequently utilized in fabricating steel structures for both industrial and residential construction. Its application extends to components of power transmission towers, equipment elements, offshore platforms, oil and gas rigs, automotive bridges, and numerous other structural endeavors.
