What is Q235B steel?
Q235B steel plate is a versatile and widely utilized low carbon steel known for its excellent affordability and adaptability across numerous applications. According to the national standard GB/T 700-2006 'Carbon Structural Steel', Q235B stands out as one of China's most prevalent steel products. It is an economical choice that serves well in applications where extreme performance is not a primary requirement.
The difference between Q235A and Q235B.
In exploring the differences between Q235A and Q235B, we find both are categorized as carbon steels. According to the national standard GB700-88, the primary distinction lies in the carbon content. Q235A features a carbon content ranging from 0.14% to 0.22%, setting it apart from Q235B.
Typically, manufacturers label finished steel profiles on identification plates before dispatch from the factory. This allows users to easily discern whether the material is Q235A, Q235B, or another grade. The design pressure is P≤1.6MPa, suitable for use temperatures ranging from 0 to 350ºC, with a minimum steel plate thickness of 20mm.
The Application of Q235B Steel
Q235B steel is a cornerstone in civil engineering, finding its way into a myriad of structural applications. It is a preferred material in constructing both industrial and residential buildings, contributing to the framework of power transmission towers, equipment components, offshore structures, oil and gas platforms, as well as automobile bridges, amongst other infrastructure projects.
