What is Q235B steel?
Q235B steel plate is a versatile and highly economical low carbon steel. As outlined in the national standard GB/T 700-2006 'Carbon Structural Steel', this steel serves as a cornerstone in China's industrial sector. Known for its affordability and broad applicability, Q235B is ideal for products that demand reliability without requiring extreme performance capabilities.
The difference between Q235A and Q235B.
When comparing Q235A and Q235B, both are classified as carbon steels. The national standard GB700-88 differentiates them primarily by their carbon content. Q235A typically features a carbon content ranging from 0.14% to 0.22%, giving it distinct characteristics.
In typical scenarios, steel mills will label the completed profiles on identification plates prior to shipment. Users can verify if the material is Q235A, Q235B, or another type by checking these plates. Design specifications include a pressure limit of P≤1.6MPa, usage temperatures from 0 to 350ºC, and a minimum steel plate thickness of 20mm.
The Application of Q235B Steel
Q235B steel is extensively utilized in the realm of civil engineering. Its robust properties make it an excellent choice for constructing industrial and residential buildings, components for power transmission towers, and various equipment elements. Additionally, it supports offshore structures, oil and gas platforms, automobile bridges, and many other engineering marvels.
