What is Q235B steel?
Q235B steel plate is a type of low carbon steel with a well-defined specification under the national standard GB/T 700-2006 'Carbon Structural Steel.' As one of China's most prevalent steel products, Q235B is both affordable and versatile, ideal for applications not demanding high performance.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies in their carbon content, as both are categorized as carbon steels under the national standard GB700-88. Specifically, Q235A's carbon content ranges from 0.14% to 0.22%;
Typically, steel mills mark finished profiles on identification plates before dispatch. Users can discern whether the material is Q235A, Q235B, or another variant by checking these plates. With design pressure capped at P≤1.6MPa and operational temperatures ranging from 0~350ºC, the steel plate's thickness is maintained at >=20mm.
The Application of Q235B Steel
Q235B steel is extensively employed in civil engineering projects. Its robust structure supports industrial and residential construction, components of power transmission towers, equipment elements, offshore structures, oil and gas platforms, automobile bridges, and numerous other structural applications.
