What is Q235B steel?
Q235B steel plate epitomizes a low carbon steel variant in China's renowned GB/T 700-2006 national standard, "Carbon Structural Steel." Known for its wide availability, this versatile material is a staple in the market, offering an economical choice for a plethora of non-high-performance applications.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B steel lies within their carbon composition, both being quintessential carbon steels. According to the GB700-88 standard, Q235A's carbon content ranges from 0.14-0.22%, highlighting a primary difference in material properties.
Typically, steel mills imprint identification plates on finished profiles before dispatch. This allows users to verify whether the material is Q235A, Q235B, or another type. Key specifications include a design pressure P≤1.6MPa, operational temperature 0~350ºC, and a plate thickness of at least 20mm.
The Application of Q235B Steel
Q235B steel grade is integral in executing civil engineering marvels. Its robustness is leveraged in the construction of industrial and residential edifices, power transmission towers, components of sophisticated equipment, offshore structures, oil and gas platforms, automobile bridges, and a diverse array of structural applications.
