What is Q235B steel?
Q235B steel plate, renowned for its low carbon composition, is described by the national standard GB/T 700-2006 'Carbon Structural Steel'. This ubiquitous material is one of China's most prevalent steel products, celebrated for its affordability and versatility, making it ideal for numerous applications that do not demand exceptional performance.
The difference between Q235A and Q235B.
In the realm of carbon steels, Q235A and Q235B stand apart primarily due to their distinct carbon content. According to the national standard GB700-88, Q235A features a carbon content ranging from 0.14% to 0.22%.
Typically, steel mills diligently inscribe finished profiles on identification plates prior to dispatch. These markings empower users to discern whether the material is Q235A, Q235B, or alternatively earmarked. Designed for pressure P≤1.6MPa; operable within temperatures of 0~350ºC, with steel plate thickness meeting or exceeding 20mm.
The Application of Q235B Steel
The Q235B steel grade is a cornerstone in civil engineering, proving its mettle in crafting steel structures for both industrial and residential edifices. Its applications extend to power transmission tower parts, integral equipment elements, offshore structures, oil and gas platforms, automobile bridges, and a plethora of other structural ventures.
