What is Q235B steel?
Q235B steel plate, renowned for its low carbon composition, is defined under the national standard GB/T 700-2006 for 'Carbon Structural Steel'. This steel type stands as one of the most prevalent in China, due to its affordability and versatility in applications where high performance is not a critical factor.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B steels lies primarily in their carbon content, as specified in the national standard GB700-88. While both are categorized as carbon steels, Q235A contains carbon in the range of 0.14-0.22%, which affects its overall properties and applications.
Ordinarily, steel mills label the finished profiles on identification plates prior to dispatch, allowing users to easily determine whether the material is Q235A, Q235B, or another designation. These materials support a design pressure up to 1.6MPa, operate within a temperature range of 0~350ºC, and are available in thicknesses of 20mm or more.
The Application of Q235B Steel
Q235B steel is a cornerstone in civil engineering, forming the backbone of steel structures for industrial and residential facilities. Its robust composition makes it ideal for power transmission towers, essential elements in equipment, offshore structures, oil and gas platforms, automobile bridges, and a multitude of other structural applications.
