What is Q235B steel?
Q235B steel plate is a versatile, low-carbon steel, widely recognized within the national standard GB/T 700-2006 "Carbon Structural Steel." Its reputation as one of China's most ubiquitous steel products is due to its cost-effectiveness and adaptability for numerous applications that don't demand exceptional performance.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B: Both are carbon steels. The distinction, as per the national standard GB700-88, is primarily in their carbon content. Q235A features a carbon range of 0.14-0.22%, which impacts its mechanical properties and suitability for various applications.
Typically, steel mills imprint identification details on plates before dispatching them. These markings allow users to discern whether a material is Q235A, Q235B, or another type. With a design pressure not exceeding 1.6MPa and operable temperatures ranging from 0 to 350ºC, the steel plate's thickness is at least 20mm.
The Application of Q235B Steel
Q235B steel is indispensable in civil engineering, providing the backbone for industrial and residential structural frameworks, power transmission towers, equipment components, offshore platforms, oil and gas infrastructure, automotive bridges, and more. Its reliability and versatility make it a preferred choice for diverse construction needs.
